1. Introduction to Chess Openings - Essentials Training Course: Hi there. This is Manuel and in this course you're gonna learn everything you need to know about chess openings. This course is for beginners. So all you need to know to do it is to clearly understand the chess rules. In this course, we'll study well-known opening ideas that include development and castling. But we'll also see more advanced concepts such as when to exchange or not exchange pieces. Prophylaxis, castling by hand, choosing the right side to castle and gambits. There are practical activities that you can download and additional tools for you, including a checklist of everything that we'll learn and games to keep after doing the course. By the end of the course, you're going to get much better opening positions. You're gonna know what to play, even against those moves that you don't know. You're gonna dominate opening sacrifices. And last but not least, you're gonna know how to break principles. So I see you inside the course. 2. Before You Start This Chess Openings - Essentials Training Course: Hi there. So I'm going to talk about three things here in this video. The first is that to do the course, you don't need anything special. You don't need any fancy so far or anything else. Just needs to access the video and to help you. In some videos, I have loaded instructions. For instance, whenever you have an activity, you don't need to pause the video to analyze the position. You can simply go to Resources and download the instructions. After you download the instructions, you can analyze the position on a PDF file without having to stop the video or to posit. Second, and this is more of a general advice. I suggest that you pause the video or you watch it again whenever you feel that you didn't understand the ideas very well. Some topics you might already know them or you might have heard about them. You might understand them easily, but others might be a bit harder to understand. My suggestion is not to go quickly because in the end is going to be harder to understand other ideas. And last I'm going to talk about jazz notation. If understand jazz notation, then you can get started with the course. If not, I'm going to briefly explain it. So basically the board has 64 squares and it's divided into eight ranks and eight fives. So the board that I will show will have the rungs and phi's labeled. So this is going to help you, if you're not familiar with just mutation and whatever you need to name a square, for instance, select this one. You will just take a look at the rank and file. And here is an exercise that I suggest to do. Just grab any GPS, for instance, night and put it on a random square. In this case it's y1, and move it to any other random square. For instance, let's say the square D5. And here test trying to find a way to get there. Name the squares on the way to that square. So the Nikon, for instance, from here to here, to here. So that will be from C2 to E3, E5. But it can also take a different road. For instance, it might go from E1 to G2 to E3, 25, probably this a little bit, and you get familiar with jazz notation. Finally, in the end, I'll give a few games and it's very easy to read. So on top we have the name of the players, the tournament, and the place on which it was played. And then you have the jazz notation. And finally you have the result. 10 means that white wins, or one means that black 1.5 means, that is draw. About the jazz notation. N stands for night, B stands for bishop, Q stands for Queen, K stands for King, and R stands for rook. If you only have a square root, that's upon that months. For instance, E4 means that the pond goes to F4 and F3 means that the night go to have three. Again, this is just a matter of practice and is quite simple to understand. So time to get started. 3. Why Chess Openings Matter, Even for World Champions : So why do we need to care about the opening? The first reason is that a game of chess normally contains three stages, which are the opening, the middle game, and the ending. So the opening or the first movers of the game where you develop your pieces. Like the position that we have in front. So from now onwards, white or black will try to develop their pieces. The middle game is a more advanced stage where you have exchanged a few pieces and now you start thinking about other plants, suggests attacking. And the ending is position lawyer, some business have been exchanged. Normally we don't have queens on the board, although we might have them. But the bottom line is that to reach a middle game or an ending, you need to go through an opening. In all of your games. You can win a game of chess quickly, and then there will be any middle Guevara ending or you might lose if your opponent plays the opening too well. And then you won't have any middle game or N. So all of your games will have an opening, but not all of your games will have a middle game or an ending. The second reason is that when you play a game, you will know what to do on the first move. You have control of the position that you will have. So in this position, if you play as white, you will decide whether you play wherever you move the spawn on a four, or whether you move a night. Whereas in a middle game or an ending, it's virtually impossible to predict what position you will have. Also, if you play a game as black, you might prefer for your opponent move. So in this position, white has a certain number of moves which are limited. And you can be bird, you replace black. We're gonna dig deeper into these concepts, the stages of the game, what to play as black or as wide on the first move. But for now, I just wanted to give you two reasons which I think are already enough for you to understand that openings are important. And I wanted it to warm up with you guys. And for that, I brought to opposition played between Lyra Christensen and Anatolia Kirchhoff in 1993 in my hands in the Netherlands. And in this position, carpet. Who is black? For those of you who do not know Carpet, he's a former world champion. He played the move Knight to H5 here. So I wanted to ask you, what do you think about this move? Don't worry for now what getting started. So there's no right or wrong answers here, but I just wanted to ask you. Think about this move. And here, white move the bishop. The bishop is currently being attacked by the night. So that's why White. Who is Christensen move division of 23. And here Kirchhoff plate the bishop 2D6. And my second question is, do you think this is a good robot move? And what would you play here as white? And we're gonna give you a small hint here. These two pieces are a bit loose, so there's an opportunity for white to attack them. So please take the position r. Let me know what you think about it. 4. Outro - Why Chess Openings Matter, Even for World Champions : All right, so you found these questions hard. Don't worry, we're here to learn. By the end of the course, you will have the answers for these questions and much more. But for now I'll start with the movie night wage five, which was the first question. So I can tell you that the move nine to H5 breaks to essential principles. So the movie is at least very risky. The first principle is the principle of activity. We can see that the night on h5 is less active than it was on F6, where it was attacking and controlling key central squares. And also the movement C2H5 breaks another principle, which is the principle of development. So here we can see that black has the Queen, the bishop, and the two rooks on the first rank. So it would make more sense to activate the species before moving a piece for a second time. And the second question was, what do you think about the moon Bishop 2D6? While the more Bishop to A6 is bad. And it was influenced by the previous both nitrate five. Because here, white can attack both pieces with the move winter to. This is actually the most basic tactic, which is the double attack. And here there is no way for black to defend the two pieces at once. For instance, if black plays Windows is seven, then y will just take the night. And if blood place among G6 defending the night, then why do we test rubbed the bishop? In fact, after the move Quinto D1 carpet resigned. So we can see that even for world champions, the opening is very important. So in the next section, we're going to study the most important tests principles to avoid making these mistakes. 5. Intro - What’s the Opening and the Most Important Idea in Chess: Hi everyone. It is weight that we now understand about the importance of the opening stage in your games. So now it's time to make sure that we're on the same page about what the opening will be for us during the rest of the game. Also, I will teach you the most remote idea about chess that will help you not only improve the Roman play, but we're just so happy for the rest of the game. So I'll see you on the chessboard. 6. Opening stage vs Opening theory: Alright, so the opening of the first moves of our game, normally around 15 to 20 moves. We're going to talk about this later. And it is the stage where most of your beliefs have been developed. Also, it is the position where you have brought your kinda safety. By developing, I mean, to get your business more active, I'm going to go through a position. Here. It's a game, and we see that white develops the night, and black develops also the night. And then the bishops. Then we see that black develops the Queen. And we're black castles. What keeps on develops so both sides develop their pieces. So we get to a point where after Black develop the bishop, the bishop is on a better position here than it was before. We see that wide has developed all of the knights and the bishops, they moved from the original square. And also the Queen now is occupied an open file. Also this rook has moved. This rock is more active. So we see that compared to the beginning. What has more active basis? We could say the same about black. We see that the bishops are more developed. So are the nights, the queen and the rocks. At least this one moved. So it's a bit better than before. And also both white and black have moved the kings. And the atleast seemed to be better on the current position. We can see that on a first look that they are hard to attack. So we could say that in this position, we are reaching the end of the opening and the BGN enough middle name. Here's an important point. There is a gray zone between the opening and the middle game, so don't worry about it. But for us throughout this course, the open new will be the point where we stopped developing our business and we start thinking about other planets. We're not going to care about the exact number of moves because these will change a lot between one game or the other. In some games, species can be exchanged quickly. Whereas now as you might have a lot of pieces till move 20 or 25. Now I want to also briefly speak about opening theory for those of you who might have heard this term. So simply bought open in theory is just the study of tests in this case, openings. And this has a long history. Writing books about chess goes back to the 15th century, where a chess player from Spain called Lucena published his first book. So as you might imagine, in 500 years or more, or we had loss of theory. Now we have videos and we have a lot of literature. So here I want to go through a position and then I will tell you some things about it. So we're not going to analyze it now. I just want to show you how at both white and black develop their pieces. But in this case we'll see a slight difference in the sense that both whites and blood start exchanging more pieces more quickly. So we see that by move 15. Here, there are less and less species. So normally even disposition, you might consider it as a middle game probably because you have almost no minor pieces. Again, remember that we said that there's no clear line between opening and middle game. So he after 17 movies, we have a position where you have no queens. And some days when we have few pieces and no queens, we might call this an ending, which is the third stage of a game. But again, this is an example, but just to illustrate, this position has been played more than 20 times. One of them was played in the World Championship match between Vladimir chronic and Viswanathan Anand. So as you can see, a lot of jazz has been studied. In any case, don't be scared because in a given position in opening, you have a lot of possible moves. This is not a forced game, so you can play many different moves. We go back to the initial position. So here, white actually has 20 possible moves. Remember that the bond can be moved to the first of the second square on the first move. And also white can move the night, tonight. And any of the bonds. So white has 20 moves. Black can reply what? 20 moves. So we already have on the first move, 400 possible moves. And that's what makes chess so rich. Having said that, we are going to study opening principles and we're going to see that not all moves are equally good. But by learning the principles, we're going to be able to find good moves in a position. Sometimes you have several good moves or possible moves. So this way, we will avoid memorizing millions of variations, which is pretty much impossible to do. So to recap, there's no absolute definitions about what such as opening and a middle game. But generally speaking, it would be the stage where you develop most of your pieces. You still keep most of your pieces on the board. And these normally happens within the first 1000 lives. 7. The Most Important Idea in Chess: So have you ever thought about what's the most important near and Jess, what really drives the game of chess? It's simple activity. And what's activity? It's the squares control by all of your pieces. If we take a look at this position, we see that white has an extra Quinn and the Queen is controlling a lot of squares. We might even count the number of squares controlled by the queen. And also the king is going to draw in eight squares. Now if we take a look at LAC skin, king is just controlling three squares. So even if we remove the queen from the board, we see that white's king is more active than black skin. Here's another position quite has an extra rook. White's king is also more active. And in fact, in this position it is checkmate. Checkmate in. It's also about having more activity. So we're going to also use this concept to understand the main goal of chess, which is true checkmate. Now if you go back to Estonian position, we see that now here we have the same number of pieces on each side. On the b's are located on the same squares. So we see that both sides have equal activity. But let's imagine that we move what species two rungs forward. Here we see that white is controlling many more squares. So in this position, we don't need to analyze further. But wider ready has a large advantage, probably even a winning advantage. So now let's go to a more realistic position. Let's say that I play E4, luck plays night to F6, our blade, night to S3. And then let's say that black plays these move, which doesn't look good. And after the war, Bishop to S4. Again, I can see that white controls many more squares on the board. So wide already has an advantage. Moving the business backwards normally is not a good strategy. And here we're going to understand it. Why? Also when it comes to the value of the pieces, we know that a queen is stronger than a rook in most cases. Also that a rock is stronger than a bishop. We can see it here in a very simple example. The row controls 14 squares and blacks Bishop controls only seven. So in the next sections we'll learn a lot of principles. But by using this concept of activity will understand them much more easily. But before that, I see you in the next video to organs and positions. 8. Activity - The Most Important Idea in Chess: Okay, so for this activity, I will ask you to check the position only from the perspective of activity. So in the first position, it is Y to play. And I will ask you to tell me what do you think about the move a bishop takes B8. Is it a good or a bad move? And here we have the second position. It is not an opening bar. As we discussed, this principle of activity is pretty much universal. So we can use it for a middle game. In this position, it is black to play, but regardless of what is white or black to play, I would like to ask you, what do you think about the position? Is white better or is black better? 9. Activity Solution: Alright, so in this position we see that whites Bishop is actually the most active piece. And we can see that the night on B8 is very passive. It might get active a little bit later, come into F6, for example, and then go into the center. But for now it's a very passive piece. So exchange in the bishop night is a really bad move. Let me clarify a few things. We know that normally bishops on nights are almost equal in value. But here the bishop is active than IT IS naught, so it is not a wise decision to exchange it. And also let me clarify that taken the nineties naught del losing move at all. But fundamentally, it's a very bad move. So you may take the night law would take with the rook and the game will continue. But you will already make life easier for Black. And these might be the first step in the wrong direction. And in the second position we see that lux night is decentralized. It is controlling eight squares. Whereas whites bishop. It is not very passive, but it's kind of attack in at night. And even if later on White takes the night than law will put upon there, or a rook. And we see that like is dominated more base on the board. Actually in this position, black laid the industry move A4 again to gain more space. And in the end, like Warner game, we'll talk a lot about the central later on. But for now I just want to draw a parallel between chairs and other games like soccer or war with dominated in the center is aki. And here we see that blacks night is definitely one of his best pieces. Okay, so I just want to recap everything that we've learned so far, which is quite a lot. So for us, the opening is going to be the first movers of the game, which normally there would be between the first 20 moves were all pieces are developed. We also spoke briefly about opening theory, which is nothing more than the study of the opening stage. And finally, we learned the most important idea in chess, which is activity. 10. Intro - Development: Hi again. So now it's time to think about how to get our pieces to become more active and answer for that is development. But in order to develop our business will need to study them. We need to know where they become more active, on which squares they are good and on which quasi or not good. Also, in a game of chess, we have an opponent wants to stop our plans. And also we want to make the plants harder. That's why in a way, development is the art of managing to get your pieces in the most active squares and tried to stop our opponent from carrying out his plan. So I'll see you in the next video to get started. 11. Where Are The Pieces More Active?: Now it's time to talk about the activity of the PCs. So we'll start with the nights in the position we can see three nights and we can see that the night in the corner, lux night, can jump to two squares, F7 and G6. If we compare this night to deny Don D5, we can see that these night can jump to eight squares. So that already shows us that nights on the corner are not very well placed. And the closer they get to the center, the barrow, DR. this other white knight already gone, jumped to eight squares. Normally it can be as good as the night, 0.05. but all other things being equal these night on the five has a slight preference for the simple point. That is night on D5 can access any point of the Board more easily than this night on F3. So the closer to the center, the better for the night. Now if we talk about the pons, we gonna see that normally ponds, they control two squares. For instance, this bone on the four controls E5 and C5. But the a and H bonds, they only control one square. So we can already say that a and H bonds normally they are worse in value because they control less squares. And similarly, all other things being equal, central ponds are better. And if they are advanced and they are well supported, they are also better. So in this position, this point on D4 is very good because it controls E5, which is a central square on associate five, which is very close to the sender. The bono need to controls to squares, but it is not controlling a central squares. Now if we take a look at bishops, we can see that there's not a huge difference whether they are centralized or not. For instance, the blood visual 25 controls 13 squares. But even the worst job in disposition, which is the bishop on H1, controls seven squares. So while it is better to have the bishop centralized, even a bishop on the corner can still be active. And when rooks, we have this funny situation, whether you place the root on the sender or on the corner, both of them will control the same number of squares, which is 14 in this case. On regarding acquainted, since we can see it as a mixture of a rock and a bishop. And we said that centralized bishops control a bit more squares than a queen on the centre, we control more squares, but a queen on the corner can still be active. Finally, kings on the corner also less active. And we'd like night on age and eight bones. But in the opening normally does very risky to get your king active. So we will not analyze the activity of the king as an asset because normally activating your king in the opening woman to get checkmated. So when it comes to knights and also ponds the closer to the center, the matter. And this makes a huge difference. Whereas for Bishop's rooks and queens, it is better, but still those species can be active on the corner. In fact, all these pieces are long-range pieces. So for the chessboard was larger, we'll still controlled more squares. Where as a night's reports, they were still control. They say number of squares. 12. Practical Considerations: Hi again, and we get back to the real world. In the real world, we need to consider that our pieces or our opponent species they can block or PCs and limit their activity. And also that our opponent will try to stop our plans. The queen is the strongest base after the Qin, which has infinite value. So would make sense to try to develop it quickly in the opening. In the starting position, the queen only controls five squares because it is dropped by its own pieces. So trying to get it out would make a lot of sense. So for that we could play a move like y4. And after Black replies with a similar buf, we could play a move like Quinto h5, which looks very attractive because it deducts three points. And also the Queen now controls minimum squares. But here only one bond is undefended. So black would simply play night to C6, which is a great move because it develops a night defense upon and there's no easy way for white to continue attacking. Let's say that we play a moonlit night to C3, developing a night which makes sense, then black place above last night to F6. And this move again develops and attacks the Quinn. Since the queen is weaker than the night, liquid will have to move. An amazingly here they're relatively best move is to go back and meet your mistake. Because if we insist on keeping the queen active, we could pick up old like window edge four. But again here black would play pickup to E7, which is another great move because it develops slight bill, develops the bishop, it improves the bishop a little bit and also attacks the queen indirectly. So sooner or later, well, we'll have to move the Quinn. Another idea would be to play a move like Quinto G5. Normally it would stop Black from the relevant inhibition because the bond is under attack. But again here black can attack the queen, and then the queen again, we'll have to move. So here if we go back, then like can continue developing the PCs. I'm over like beach up to before is great because it develops the bishop and it has this threat of taken the night and then taken upon. So as we can see, developing the queen, even though it's the strongest space, is normally not a very good strategy in the opening. Now we go to the second strongest piece, which is rook, their work on each one and say we start with this rook. It is again trumped by its own pieces. So if wanted to develop, it will play a move like H4. But here, even a movie like d5 will stop the rook from developing. Because if a playbook to 83 then takes, and we know that the bishop is weaker than a rook. So this is a good deal and would exchange for black. But if we go back also here, like Bombay movie, like e5, instead of the five, both homozygotes, because we can even allow white to develop the rook. Because after rook two, 83, we can play the five again, attacking the rook and has to move. This is the main point, since it is a very strong piece. It has to move when it's attacked by bishops are knights or ponds. So here again, the relatively best move is to go back, to admit their mistake and go back. Because if we play a move like group to have three, then we might even consider taking the bond. This looks like a free bottle. And if you played the mook to E3, this looks attractive because we took upon, but again, like conceivably defend. And these Ruby's not well-placed here because black can attack it sooner or later would have move like D4. Also if a play night to F6, then sooner or later nitrogen-14 might be an idea. And last but not least is rook is really annoying. White development here the Pantone tool cannot move. So if we wanted to develop the bishop on this diagonal, it is not possible. So this rock is not well based at all there. So now we need to check bishops and nights. So bishops anomaly if we can develop them, that's great, but sometimes not well, moves can be bad. So in this position, it is black to play. And if a player moves like Bishop to C6, we would say, OK, this looks like a great move because now the bishop improved the precision. Now which is attack in on this diagonal, kind of looking at whites king, so does look like a great move. But here again, we need to consider that we have an opponent. So here you can pay us a move like D4, and he will gain tempo. He will attack our pieces. This is the main idea of developing pieces. By gaining timber, I mean that you develop on your tackled this int dimes. Normally this is a great strategy. So here, since black has to move the visual because the pawn is weaker than the bishop. So here, if that plays a move like Bishop to be six, again, we can develop another piece. So five is not a good move. Instead, here, like night to C6 would make no sense to develop a knight or a move like D5, contour attacking the sender. Or we might even consider development the bishop 27, although here it's not very active. But I, at least here it cannot be attacked. And when it comes to unite, similar idea. If we can improve the night, that's great. But if we improve the night, but we allow our opponent to attack us, then that's normally not a good idea. So in this position, it is Y to play. And a movie night to D4 would normally look good because we bring the night closer to the center. But here the night is not stable because it can be attacked easily. Hear black can play actually many, many moves. One of them is S5. Again, attacking and improving upon little bit, it's more active. They're also like could attack with Upon 25. And also we can even ignore these movement because it doesn't have any threat to, we could even play a move like Bishop to G7. Remember that the bishop on the corner or close to a corner is not necessarily bad. In fact, here the bishop is great because it's indirectly controlling these long diagonal. And actually here we will have a threat. So let's say that what plays him over like Bishop to S4 than black and simply take upon. And we see that the bishop there is not passive at all. So we sacrifice a night, but we got it back. So remember that queens and rooks are the strongest species, but they are very hard to develop in the opening because we have weaker pieces like pawns. Bishops are knights that can attack them. And remember that concepts are not absolute. Before improving a piece, we need to double-check if our opponent can attack us or not. 13. Which Pieces Should You Move First?: Welcome again. So we now know that developing queens and rooks is not a good strategy. So now we have to decide what pieces will develop first. Since we spoke that also developing the king or activating the king is where risky, that leaves us with ponds, nights and bishops. So we spoke dot nights. They have to go towards the center and ponds the closer to the center of the better. That's why a move like y4 and disposition is very logical because it activates the bishop. And although we won't develop the Quinn early, it still leaves some squares for the queen to develop later in the game. Another logical move here is to play a move like d4. Because we improved upon, we put it on the sender and we activate the bishop and will leave more squares for the queen to develop. So if we play again e4 than, let's say the black replies with Y5. Here we have a position we're developing the night is ever logical move because we play the night towards the center. And we also attack upon, in fact, in this position, this is the most common move, nine to F3. Here we said that developing the queen is not good, but we could think about developing the bishop, for example, to C4. But the bishop is already controlling some squares on F1. So Bishop does y4 is a good move, but neither three is a more natural move because we improve the night and the bishop still has some activity. So when disposition, The point is attacked. The most natural things to defend it. And here black has several options, belief and upon. One is night to T6, the other one is D6. We could also consider a move like Bishop 26. But if we follow the same principle, developing the night is more logical because we approach it towards the center and the bishop is already a little bit active there. So the movie night to C6 is more natural than the move D6, because the move D6 only defense E5. But it doesn't improve this spawn greatly. So let me clarify again. Over the CX is perfectly playable, but the move nitrosyl Cx is more common is this position because it is more logical. Here we have another position. It is black to play. So here the most logical move is night to F6. Because you develop a night towards the center, you're already prepared to Castle. Whereas another move like D6 is possible here because you open line for the bishop, but I would say that night to F6 is slightly preferable. Here we have a similar position. I like to work with similar positions to illustrate ideas. Here it is blood to play and hear, like has lots of moves. But again, the most natural move is night to F6. So let's check some alternatives here. Black could play E6. They move E6. It gives sum squares for the bishop, maybe for the Queen. But remember that developing the queen early is not a good idea. Maybe also for the night, but also it closes the diagonal for the bishop. So the movie is possible, but it's less logical than the move now to S6. Another possibility is to play night to C6 because we want to develop night. But I would say that the move Knight to F6 is slightly preferable because not only develops, but it also attacks. So here it is Y2 play. And again, the logical move is to develop a night and defend. Whereas here white also has many ways to defend the pond, for instance, with the bishop or with a pawn. And again, these moves are preferably playable, but they're a bit less logical than the move nitrate C3. If we get back to the initial position and say that a player moonlit night to s3. Then here black, play a movie like D5, which is quite interesting because we are limiting the action of the night. So to conclude, you should develop minor pieces, which are knights and Bishop first and bonds if they go towards the center. Also, when you come to minor pieces, normally it is slightly better to activate nights first because bishops on their initial positions might already be active, like we see in this case, this bishop associate already has some activity where this night on G1, for example, is very passive, just controlling two squares and far away from the center. 14. When should you Exchange pieces in chess?: The two most important idea that you will consider when exchanging pieces in the opening are first and foremost, the material balance. So you should simply ask yourself, if you are exchanging a weaker piece for astronomer piece. If we go back to the position that whichever we wanted to develop the rook. And after blood place d5 will play this bad move. Then we'll definitely exchange a beta for a rook because we know that normally are obese stronger than mashup. So if they exchange is material is good for us, will do it. So that's quite simple and straight forward. Here we have another position which is black to play. And despondency five is attacked. Remember that we said that central ponds normally are the strongest. So in this case, it would make a lot of sense to his changed this S5 bone for these Poland before. In this Ella position, despondency five again is being attacked. So we could exchange it. But in this case, if we exchange the opponency five, white will also get the pawn on the c file to default. So in this case, this exchange is equivalent. In fact here, white also gains a square for the night. So this exchange is not necessarily good for black. Let me clarify that this is a perfectly plausible move, but here we might consider other options. For instance, above like E6, which defends the pawn. And here, if y takes a dubious move, because here black will take the pond and he will exchange. I've got central porn for a weaker bond. And also black will develop obese. So taken on C5 would be a very bad move for white. So if we remember what we'll discuss about which bases which are developed first than here, the most logical move would be to play night to F3. Because we develop a night towards the center and all central ponds had been developed. And we have analyzed this position in the previous lesson. And we concluded that the movement into F six is the most logical move. Here we didn't analyze the idea of exchanging species, let say will change at night. And then we exchange bishops. So materially everything remains to equal. But here these exchanges are not advisable for black because in the end, white just improved his queen. And here the Queen actually is quite active. And also it is not so easy to attack the queen because there was no night on CCS. So when exchange in first, double-check if the material balance is better for you or not. And secondly, if the material balance remains the same, ask yourself, if exchange in pieces improve your pieces or your opponent species. 15. Prophylaxis in the Opening: Welcome again. And now electorate to talk about a very interesting idea. So we spoken that development is the key idea in the opening. But there's another tool which is called prophylaxis, which basically means to prevent your opponent from Cari. Now to plan, in this case, we're talking about development. So either we can develop our PCs or we can prevent our opponent from developing PCs or from improving pieces. Let's take a look at some examples. In the first position, it is Y to play. And white could play a natural move like D4 to plan to develop the night later on, or the bishop to burrow squares. This is perfectly possible, but in this case, blood can also get active plane, the move Bishop to d4. So here the bishop is putting pressure on the night, which is support in the center. So with that in mind, before playing the move, before we can play the movie h3. These might look like a passive move. We spoke that the eight and a pawns are the weakest. But in this case, we want to prevent black from blame bishop, did you form. Let me also tell you that prophylactic moves have upgrade psychological value because when we prevent our opponent from Korea to plan, we might frustrate him a lot. So this is a very interesting weapon. After H_3, we can plan to play the four later on and have more control on the center. Sometimes we need to see our opponents plans way in advance. In this position again, it is Y to play and black is planning to develop the pieces. And for example, this bishop and C8 doesn't seem to have a little future. But after moonlight night to be six, it will attack the bishop and then the bishop would develop. So remember that night to be six will come with tempo. It will attack the bishop. So the bishop on C8 can develop very quickly. That's why they move. H3 is very interesting, and again, continued after it takes, before, it takes E4 night to B6, wordplay Bishop to V3. And here black doesn't have the mortgage up to D4. Although black can develop the bishop to a five here, it doesn't seem to be doing a lot of harm on whites position. So the game continued on. Kasparov won the game afterwards. Here we have another position. So in this position above like 83 doesn't make much sense because here the mortgage up to D4 might be interesting, but it's not a big threat since black already has some control on the floor. So here in this position, what might develop pieces? Definitely, we could play a mobile I wish to have for it is perfectly playable. But here we also have uninteresting idea, which is to prevent plugs, mains idea. Here, blood might want to play a movie like B5, and later on might attack the night, putting some pressure on this bond. So here above like a form is a prophylactic move and he's a very interesting one. Let me also tell you that these prophylactic moves, although they might look passive, they are useful moves. It is a very important point because we're not going to waste time doing a move that doesn't help us. Let's imagine that we have this position. It is what to play. And as we discussed here, would make a lot of sense to develop nights or bishops. We already developed the night and F3. So here a move like A3, preventing a move like Bishop to be Forum would be actually very bad because bishop to before is not a threat. Here. Instead, if you play a move like Bishop to S4, then if blood place Bishop to before, then we can play many movies. One of them is to continue developing. We might castle or we might attack the bishop with a mobile like C3. If Black wants to play a move like Bishop to C5, which is not very good, probably will actually Retreat 27 here. But again, this move Bishop to before doesn't make sense. But if Laplace or move like Bishop to S5, then we mapped them before. Remember bringing points to the center if we can do it is great. Attacking, also attacking the bishop. Bishop to b four is not a threat at all. So remember prophylactic mobiles are moves that prevent our opponent from developing. Um, they're very useful moves. 16. When Can You Sacrifice Material for Development?: Hi there. So we already know how important to develop. So not surprisingly, sometimes development is both material. So that means that we can give material to get more development. Or our opponent might try given material, sacrificing material in order to get more pieces developed. This is definitely a more advanced topic, and for now I will start with a rule of thumb, which I think is very useful when it comes to sacrifice the material, which is that having three more pieces developed is normally worth upon. Again, this is not an absolute rule, but it is very helpful for us to evaluate whether the sacrifice is good or not or dangerous for us. Start with a position that will recheck, to illustrate this idea, will discuss the developing the queen early is not a good idea. And when we play them of like window H5, then black would defend with nato C6, which develops a night. And if a played a movie like night to S3. And then after night ref six there, we said that the best was to go back to admit the mistake. And we spoke that if we play queen, which for then like would attack, would develop an indirectly attack with the move Bishop to E7. Also we discussed that play them over like window G5 instead of conduits for was not good because black might attack the queen with H6. But here we might even consider a move like Bishop to S5. So again, we develop a piece. And even if we gave upon and if y takes it, then black we developed the rook. So here it's quite interesting to mention that like developed the rook to an open file and it is very active. Also drew, cannot be attacked easily. We can see that black has a lot of pieces developed. Also, the queen is not well placed there because it can be attacked easily. Here this black to play and any movies, good for luck here. Actually even black has a very strong move, which is taken upon because it takes then the overnight to D4 when, when the Queen. But even if luck doesn't have any move and in a red move, he has a lot more development. So he has very good conversation for the pond. So this position is extremely dangerous for right. Now we're going to analyze a more theoretical position. After the move E4. Then black plays C5, which is called the Sicilian defense. I'm gonna give some names throughout this lecture, but don't worry too much about the names. We are here to understand how to think the positions r1 to memorize names. So here are the moves, FIFA, the Sicilian defense are normally white develops the night here, which is a very logical move as we discussed, developing night is great. But here white might try to play the move D4. And here, taking the bond makes sense because it doesn't well pawn. And here instead of taking with the quinn, Because if we deal with the Queen and like would develop a piece, would tempo, tagging the Quinn. Here, white might dry the move S3, which is a pawn sacrifice. So the main point of the sacrifice is that if light takes the bone, then white develops, takes upon, and develops a night. And as you can see, why it already has a lot of open lines. So white, white faces will develop very quickly. For instance, if black tries to develop the night, then why develops the night? Here ready? Black has some problems to develop. If a player moves like my draft six, then we need to consider this move because we don't have squares for the pieces. So here if Laplace above like D6, then why develops very quickly? This line is not forced, but I want to show you how wide develops very quickly. So they say luck plays a move like nato F6. Then when do we do? Two is seven and rock the one. We see that wide already developed a lot of pieces. And here in fact is already threatened to play a move like e5 because this rock is looking at the queen. So here white has a lot of compensation. And also disposition becomes very hard to play for Black. So if we go back to the position, to the sacrifice, which is called the moral gambit. By the way, a gamete is an opening in which white or black sacrifices material. And here, white tries this gambit. This is the gambit because white is offering upon black is not forced to take here. Because dig in here, we're helping develop the pieces. I'm going to flip the board so that now we can focus on luck side. So here, if we take, then, as we said, why do we develop pieces? Instead, we can draw alternatives, which is to not take the material and focus on our development if we analyze the position from black side. So here we might consider a move like nine to F6, which is developing move and we attack upon. So this seems like a very good idea. And after a move like you five, they will play nitrogen F5. And we play the game without gaining material but developing more pieces. So this is a very interesting way to continue playing the position. Also here I want to mention another interesting move, which is maybe a bit more complicated, but the movies D3. So this move is given back upon. And we don't want to give the squares for the pieces. For instance, we don't want to leave the square for the night, and we don't want to open too many lines. So after white takes it upon back, then we can simply continue developing and then the game will continue. So here I would advise you if you're playing disposition as black, probability is better to give back the material unless you are very well prepared on this line and you want to accept the material. But remember here, development is more important than material. Here we have another position. And here again, I want to illustrate the importance of development that sometimes we get even sacrifice more than upon even a full piece. It is black to play. And we see that luck is upon Up PAD wide already has to be developed and why it is developing very quickly. That will castle will try to open lines. We see that this King is still not developed. So here, black should normally consider developing pieces like the bishop to G7 or the knitr C6. Actually disposition is a bit complicated because developing the night is not so easy because you play a more than NIH to F6, then we might consider moves like e5. But actually here, even if black price to pay a move like G4, this moves attacks at night, but again, lag is not developing. So here white might even consider a move like canceling instead of or in the night. The point is that after taking the night, then why do we capture with a queen? Here we develop the Quinn, but the queen cannot be attacked this list. So the queen is actually very well taste. We can see some ideas like taking this bond and then put in a lot of pressure on F7. So this position is not one by wider block. All I want to say here is that this position is extremely risky for black because although black is a piece up, black is very underdeveloped. And also his king, my zombie, came under attack. So remember that development is so important that it can be both material. And whenever we face sacrifices, we need to seriously analyze the position and consider given material back. 17. Activity - Development: Alright, so let's now do an activity. And in this first position that we have in front here, it is wide to play. And I would like to ask you, what do you think about the move? D takes E5. So here we will be exchanging the Poland before fall upon on your five. In the second position, wide, just played the move a3. So I would like to ask you, what do you think about the move a5 by black? And in this third position, let's imagine that white starts the game with a four, which as we saw, is not the most common or most logical move to start E4 or the four archaeological novels. And here blood complain many moves. For example, D5, 9-12 seeks to develop is a move. But let's imagine that blood sacrifices upon with the move E5. And after taking place they move D6. And let's imagine that wide takes upon on D6. And here we will deal with the bishop. So here while it has an extra proton, and I would like to ask you, how would you evaluate this position? 18. Solution - Development: So in the first position here, taken on E5 is not the most critical move because here we will be exchanging Apollyon D4 four upon D6. The Poland before is a bit better placed than the boron D6. So after taking only five, like one day with a bone or blood can also deal with the night. Because in this case, we will be bringing a night towards the center. These night cannot be easily attacked. White can exchange in ice here. And after taking only five, we actually get a symmetrical position. Here one might dry exchange in Queens, but after Exchange in Queens, we get a very equal position here. For example, black can bring, they came to the seven, avoid tries to attack the king by bringing a rope to the one, for example. And they came there on the seven is going to be very safe. So after Dignity Five, asset black can also deal with the bone. So here black has more than one option, and here is why continuous developing. Here black can also bring the bishop to S5. So now that black 2C with the point on the Sikhs now, black can even improve. The bishops of the bishop on S5 is a bit more active, not only seven. And these position is a bit more complicated than taking with the night because here, if one wants to be aggressive, why control plane him overnight to G5? But here black and defend the Pantone F7. And here black is developed in the night, although the night on H6 is not very well-placed, white is wasting time by playing them overnight to G5. So this position is complicated, but can be playable for black. So taking n5 is possible, but probably not the most critical move. Here. Developing the bishop to S4, for example, is the most natural way to continue because the bishop RC4 is very active. It's looking at F7 or blame the move nitrate C3 to develop the Night is also a more natural move. In the second position here, playing the movie A5 is a good move, can be played because the movie twice to stop before by white. So here white play the movie A3 and plants to play B4 and B5 are dug in the night. And then even to undertake this very important born on a five. So the move A5 is a logical prophylactic move that can be played. On the other hand, as we discussed in general, one to develop pieces before bonds if again, so White's plan is a bit slow. White wants to play the movie A3 and reform. It is not about plan, but it is a slow plan. So here black can even ignore that idea by cancelling. And after, before. Here black actually has an inverse Nadya widgets to play anymore because of the V6. And if white guys don't get upon after 934 here, taking only five would be very bad because black would have the job to be three. And the only square for the queen is E1. And after night to C2, we would win a lot of material here instead of B5. And getting the born here y can be any other movie Group to be one. And now here, like undefined upon after a movie like F6. And this is a very common position on which black is doing fine. So here in this position, playing them away, five can be played, but also casting or Blaine, Any other developing move is also fine for black. And in the last position, playing them all for, as I said, is not a very typical movie because it breaks developing principles and also moving the F born might expose wise king. Does y here in this position, black can play many moves like the five S5 night to F6 and have a good position. But black can also play an aggressive sacrifice after the movie five. By the way, why does not forced to date the bone? Why don't blame over like d3, which actually will be interested in because after taking on a four, we will develop a bishop, modify these greedy and takes it upon. So here, black sacrifice upon. But as we see, black has already developed. A bishop. Bishop is already quite active. Also the Queen might develop, so black gave a bond, but black here has a lot of compensation for the bond because black will develop a reactively white has to be careful already because if white plays any natural developing more of like nitrosyl three here, after the move Quinto H4, we see how moving the spawn exposed wise king. And after D3, which is the only moving the position here, we just Dagan g3 here. Instead of taking the mook, we can even take this bond and give a checkmate. So he had the best way to stop these idea of quinn rage for is to develop naturally. So night where three is the best move here in this position by black has a lot of compensation for the bond. 19. Well Done!: Hi again, and I wanted to congratulate you. You made a huge progress on jess openings. In this section, we studied the main goal of the opening, which is development. And for that we studied how to develop the PCs, which basis we should develop. So now we have a very solid foundation to move forward. Not only that, also in this section, I'll introduce very broad topics which are exchanges, prophylaxis, and sacrificing material. These topics not only impact the opening, they can impact the middle game, the ending, and they are very, very important. So I'm very happy that you are now aware of these topics. So now it's time to move forward and to keep on learning more key opening ideas. So I'll see you in the next video. 20. Intro - Castling in Chess: Hi again. So now it's time to analyze canceling, cancelling. I wanted to analyze his separately from development because strictly speaking, it is not a developing move, at least for the king. Also will analyze the difference between clustering short and gasoline long, and will answer the question whether one is better than the other. Last but not least, some dance, our opponent might give us a check or my take a pawn and we have to take with the king. So in the end, we might not be able to castle. So in this case, we need to think about what to do with the king, to improve the position of the king, and how to find good squares. So I'll see you on the chessboard to check this. 21. What Are the Benefits of Castling?: Okay, great. So first I want to go through the very basics of gasoline. So as we know in a position we can castle short or castle lung. To Castle short decaying moves to squares to the right side and took us long. The king moves to square to the left side. It is also an easy way to remember how to Castle. Just move your king to squares to the left or to the right. Now I wanted to note a few interesting things. When we castle short, we have two squares between the king and the rook. And that means that these two pieces, which are the bishop and the night, they need to live. Whereas when we consult coincide, we have three squares. So the Queen has to live, the bishop and the night. So in a way it is harder or it takes more time, more Tempe, as we're saying, tests to gas along. Thus why in most of the games, when someone castles, he or she will castle short. And the reason is that it is easier to Castle short because you need to move less species. Now we also wanted to analyze cancelling from the point of view of activity. Since we spoke that activities essential. I also want to see is this benefits astronaut activity wise. So when we castle either short or long, normally we improve the precision of the rook. Would discuss about rooks that they can be active in the corner bar in the opening. Rooks are very passive on the age and a files. And the reason is that normally we have ponds there, either opponent H2O, NH3 or a2. And since we start moving the central ponds first because we spoke that central ponds are very upgrade to move the opening. There's a higher chance that these bonds are traded. So that would leave us with open files or semi-open, what we call open or semi-open files for the rooks. Therefore, rooks can become more active as they go closer to the center. That's why when we consider short, we get our rook a bit more active because the rook gets closer to the center, it gets to the file. Also, the file is more likely to be opened and the.h file. So we improve the rook. And when we castle along the Rockies array, normally very well-placed because it is a central file. So Kosslyn gets a rooks more active. On the other hand, when it comes to the king, what we consider short or long, we bring the King closer to the corner. So in this case the King becomes a bit less active. But as we will see, the main goal of cancelling is to bring safety to the king because it can become easily check Omegas. On the other hand, in the ending, which is another stage that will not study in this course. It is normally very good to activate again. So here, in a sense, we are worsening the King's position for the ending, but we're definitely in Bruner for the opening. So we can conclude that cancelling improves the rooks in most cases and normally brings safety to the king. So now I want to illustrate this idea of King safety with a few positions. And for that I chose games from former world champion Mihai, it'll, who was known for his ferocious antagonists style. So in this position he's playing against an amateur. And here he played tallies wide and he replayed the move C5. So the MVC five is great because we attack a night. Also these Bishop now might become dropped after Mosaic a3 or before. And since black has to move in the night, here he move night 637. Now we have this great move, 96, and the night cannot be taken by the bishop. So these forces like to move. So black cannot castle because the king is injected. And after King to E7, we see that there is some traffic jam with black spaces. You know, they're not correlated at all. This night looks very passive. This rooks, they look hard to develop. So whitespace, you know, is so good that here it'll play the amazing night tasty four, which seems to leave the queen undefended. But the point is that if we take the Quinn than rook takes FC7 is checkmate. Thus why blood played the movement. I take the five maybe to bring an escape route for the king. But Tal insisted with the amazing movie quintiles div, or the point is that if we take the queen, then rope takes FC7 is another beautiful checkmate. On here, black tried another move, another desperate move, much uptakes E5. And here followed another strong move, which is rook takes FC7. Check. And the point is that if we take, either would take the night than quintic C6 is checkmate. Or if we take the rook than quintic C6 and Quinn F7, F7 is checkmate. So here black skin is so badly place that y can find these amazing moves easily. Here we have another position by the great towel. And here tell again, wants to attack. He was a very aggressive player. And here black played the move to D7. And it is actually quite dubious move because once I want attacks as one of the main weapons is structurally counterattack. So here blood should have played a move like Bishop to E7. To have some replies after Mozart Quinn to F3, we could have, we could take this night or think of moves like rock to a fade. But you know, we need to be active here when we defend, normally is a great strategy. But after Bishop to D7, white took the night. And after blood took upon, then White played the following forcing moves. Quinto H5. And here black played him with G6. There's no king is seven because quintile have seventies checkmate. So this is forced. And after G6, what made the move? We're going to have three. And there is no way to defend against Quinto F7. For instance, if black plays a movie like Queenie seven, then we can take on S5 and afterward tactics and z5. We have this force in sequence. When F7, jack, king and queen F6 attacks both the king and the rook. So why do wins a lot of material. So cancelling is very important, normally improves the position of the rooks and also brings the kings to safety. And later on, we might study some cases we're casting is not good, but in most cases, it's a great strategy. 22. Should You Castle Short or Castle Long?: All right. So we spoke about the manifests of cosine short and the manifests of Castilian long. But now we need to consider that in some cases, we can castle on the long side or the short side. And we need to decide which one of them is better. So we'll start with our position. Here it is Y2 play. And hear white can easily gases short by playing them off like Bishop to V2 or to move the bishop somewhere else. And then castle, let's say after black plays B job to G7, then when castle short. And we have a game, perfectly playable game. But instead here, what can play the movement of 2p3? And after a move like Bishop to G7, then one can play F3. Defending the spawn, reinforcing the bond because upon history defended. And after cancelling Quinn D2 and after him over like nitrosyl S6. Here, wildcard developed the bishop. We spoke that developing minor piece is great and so does black. And here, white can play the movie long castle. But also what can play the movie short castle. So these might look like a very difficult choice because both of them are perfectly playable. So which one to use? So the first question that we need to ask always is, is making going to be safe on the side, I'm canceling. So here if Lucas along, then we see that the king looks fairly safe because the king is surrounded by a lot of pieces. Unblock doesn't seem to have a lot of pieces attacking again. So maybe this night about this visual is far away. Maybe they ruled will join, but still the king. Perfectly safe here. Now how about we GSL short. Short then does my king looks safe here? On the answer could also be that yes, it looks a fear. The Queen my gun to defend the rule base shop. And also I don't see a lot of black pieces are DAG. And again, so again, this is the main question that I'm going to ask. And in this case, the King looks safe when we castle short Antoine who gas along. Therefore, both movies are perfectly playable. And here comes the second question, which is more of a matter of style. If I castle long in this case, here we have what we call opposite side, Gosling because black skin, castle short and wide King castles long. So both sides will try to attack each other normally by pushing ponds or attacking with basis. So in this case, when I talk about pons here, what can push, pause easily? And since the king is not on the king's side, they King is not going to be weak. Whereas in a position like this, if y starts pushing the pons, the King may end up being very weak. So normally cosine on an opposite side to the opponents King will lead to a more aggressive play. So if white is more of a quiet player, then gasoline short seems like a more reasonable option. Here we have pretty similar situation. So here, White Castle, shorter GAS alone. And again, we see that if white causes lung, then he's king also looks very safe because there are many business around the king. And in this case, we might think of an attack portion ponds or exchanging pieces. But also it looks perfectly logical to Castle short. Then this is more of a middle game topic, which is not the topic of the course, but here, it might look a bit harder to find a plan for wide in this position. So maybe gasoline is more natural. But both moves are perfectly playable. If we take into account that the king is saved on the king's side or on the Queen side. Now in this position it is blood to play. And black can castle short, or blood kin castle lung. So in this case, at least for now, I don't see an immediate danger for black. Maybe white can try pushing ponds here, like D4, D5. As we said, normally, this will weaken white's king, but also invited Tag Block species. So this is double-edge. It is received for white, might be dangerous for black, but it is a game. Whereas in this case cancelling long, we see that we have a different situation because they coincide ponds are more advanced here. And these bonds can be attacked easily. Although in this case, black has pieces defending the king. Here the ponds may become under attacked directly with a move like a four. And actually hear black already has a lot of problems because if we move this bond than this bond will fall, would check. And if not, then white will take here and open this line for the rook and black skin will become under attack. So remember, first and foremost, safety of the king is the most important point. So if you are going to cancel short on your king is safe, then that's good. If you've got a long and your guinea safe, that's also good. And secondly, if you can play both of them, then you will decide based on a matter of style, whether you want to play more aggressive chess, a 100 to a dagger upon directly, or whether you want to play a long-term and more quiet game. 23. What is castling by hand?: Welcome again, and now we'll talk about gasoline by hand. What's cosine of my hand is just, just jargon for reaching a similar Castilian position. But by moving your king and Luke separately, also called artificial Gosling. But in any case, what we need to understand is that sometimes when we can castle, we still want to improve the position of the king. Let me give you an example in the following position, it is Y to play unless imagine that the white texts upon on F7. So normally this is a very bad move because we know that upon is much weaker than a bishop. So here we can take the bishop with a king. And like has material to London. So normally black is much better winning, but the king is not going to be able to Castle. Also here the King My become under attack or maybe checked easily, let's say after moves likes night, we have three and nitrogen five. If the Queen goes to it to, it can give a check on this diagonal. All in all, they King is not very well placed there. That's why black could think of ideas similar to gasoline, which is to develop the bishop and then bring the rook to their file, which now is a semi-open file. So the rope is going to be very active here. And then possibly bring the King to the eight and then to age eight, where checking the king is going to be much harder. So here black would be Kosslyn by hand. In this example, blackish easily women. But let's check some more realistic examples. Here it is y to play what has a strong center. But black is trying to counter attack descender BY has very active pieces so far, more developed pieces. So the position is not easy at all. For isn't Blackman. Ids like FCX and G5. And white needs to develop PCs. Here it is y to move. So the king is under check. If you played it not well movies like me jump to the two or nine to the 2x. Then black would simply take the point on the four here, like tasty four wins upon for block. So this is not a good idea. That's why, why play the move kingdom OF two. Now here the king is also not very well-placed, but as we said, white has some advantage in the form of space advantage. So here, black immediately play the aggressive move G5. So I really like this example because white really has to find a safe haven for the king. So here, White played him OB1, OB2, OB3, which is a great move because developing normalised Great. Instead, if we take the bond with the night is not a good idea because again, the four will fall. And if we deal with a pawn, then black has the very strong night 85. And black got a central porn for a G bonds. So this seems like a very good exchange for black. The point is that after taking only five, would take only five again. And this point is pinned because the point is looking at the King. Software, b2, b3, black played the move F6. And here Y developed again, which is great. So here we have the position would have six, which obey three. Then black to connect four. And after some exchanges, blood plate, they're very active, rookie fade. So this is an open file there, OK, here is looking at the king. So this is a very good move. That's why white continue developing. And after the bishop to E7, which is looking at the bone, what defended, So what is making a lot of defensive moves. But here the Pantone sixties attacked. So it is now Blackstone to defend. So we see that sometimes a Dunkin, if we don't achieve our goals, could end up backfiring. So here black has to defend this bone and played the move Knight d to be eight, which is very passive. And here, White played a move, relocate to a F1, which is the square of the rook occupies one white castle shorts. And after night to A6, what continued with K2 Jiddu also, can G1 was possible and will reach a very similar custom position. So when we speak about gasoline by hand, we'll reach very similar gasoline positions. And in the end, after we shipped to D7 and nitrogen five, rook G8. Then can we say that finally, wise king came from F2 to G2 to M one. It would have been better probably to do it at once counseling, but Black didn't allow that. But on the other hand, black waster Tempe force in y to do that. So in the end, quite got a very reasonable position and actually won the game. Here we have another position, it is Y to play. And we see that these two bishops are attacking each other. And what kind of castle? Because if we cancelled, then we lose a bishop. Also if we take, then black will take. And at that night. So these exchange, remember that exchanges, we wanna make them if we improve our business. And here these night on D5 is white space. And if we have to treat it, then this is not a good deal. So that's why white play, they're very creative and interesting. Move king to F1. Because now the king will come to the king site, but they're still defends the bishop. So here again, we waste time, waste Tempe, as we call it in chess. But on the other hand, we keep our business active and we're laughter A5, Kinsey do. Then in the end, continued playing rugby F1. And also what here achieved a reasonable position and also won the game. So remember, if gasoline is not possible, we need to think how to make our king safer. And if that means going into the corner that we can replicate our gasoline setup to improve our position. 24. Activity - Castling: Hi again. So let's practice a few positions. In this first position, here it is Y2 play. So let me ask you, what do you think about the move A3, which was played in the game? And in the second question, I want to go through some movies and then ask you, what do you think about the resulting position? So let's imagine that here I blade the move E4. Black can reply with the move E5, which is a common idea. After night to F3, we develop a night. Black can develop a night and defend. And here white has many ideas like Bishop 25, but let's say that we play them overnight to S3. And here that also has many moves like night to F6. But let's imagine that here. Black Bayesian move Bishop to C5, which is an annual developing more looking at this Pantone F2. And here white also has many options. For instance, developing the bishop to Z04 is very natural, but a possible move is the seemingly weird night take S5. And the point is that after the gurney five, where we'll pay them of d4 and get the piece back because we have a double a DAG, for example, after Bishop B6 and then deg N5. Take N5 here. Why do not the piece back? And we have a fairly equal position. However, here before take N5, black and dry them, move. Bishop takes F2. And here White takes the bishop because like gave I check are now after dignified here, y can dry them, move the 4x, which is interesting because we just improve the bone and attack denied. And let say that after a move like nitrogen six here, I would like to ask you, how would you continue here as wide, so white count castle. So we need to think about a way to develop RPCs in another way. 25. Solution - Castling: So in the first position, blame the move a3 is risky at best. So we know that we want to develop or to improve our business and respond how the a and H bonds normally they can be moved if they prevent an important idea. Otherwise, we would like to develop PCs or either move central ponds forest. So here what has to be actually quite careful because black is planning to give a check, planning maybe to take this polygon D5, but also a more like Bishop to a five might be an idea to then give a check on C2, attacking the king and the rook. For example, here are not dwell move like wind to B3, defending upon here, blackboard. Continue with chapter five. It's already getting complicated for White Knight two, c2 is a big threat. Here. D3 was an interesting idea, trying to stop this tape on d3 and then trying to Castle, for example, Blaine, I do we do on I do F3 and tried to Castle short here black. So Dr. Bishop to a five. And here y can dry Bishop n4. And their position is very complicated because you're like am blady move Windows seven, pinning the bishop. And here y would have to defend. But for example, he after the move Bishop 2D6, planning to win the peace. Here, y can dry a move like A3, counterattack and denied. And we get a very complicated position, but much better than in the game. Because after the move a3 here, black did not take the poll on the five, which would be a good move. Unblock would have a very good position. But here black continue with the movement i to the three. And why don't we able to castle here, came to F1 is the most natural move. The king on E2 is really endanger there. And here black continue with them obituary seven. And although black sacrifice upon here, black has a lot of conversation because black has more development. And also wise king is really not doing very well there. Why speeches are not coordinated? The speedup on C1 cannot develop easily so far. And in fact here black. I probably won the game in just a few moves. The game continued Quinto V3, and here black sacrificed and another bond. And here white dried G4 with the idea that if black dx, then we'd take the night. But after C4, like kept on sacrificing bonds in order to open the position. And a DAG white skin here after Queen takes B7, B8. Here we see how black sacrifice a lot of bonds, is attacking the queen each time. So we see again how developing the queen is very dangerous. And after query for each of the seven, Winn-Dixie four. So here black sacrifice actually four points. But after the move, wind rage for we blend to give hijack made here, why gave a check? But in this case, like a neon blade, they move kinda the aid because black will bring another piece to the attack. And after quandary, three-year-old create, in fact, he already wide resigned because root two E one is coming under VC way to defend that, For example, after nitrate do Bishop dignity for we just attack the queen and the night. I'm like we'll gain a lot of material. Now in the second position, we have these weird position on which wide cannot castle. So here white has many options. Some of them are good, some of them are not very good. Here I like the more visual to S4, which develops an essential login at F7. And next we can play the movie group to have one bringing the rope to an open file. And later on if needed, kinda g1. So here White cannot castle. But on the other hand, what has better development? These two bishops are really very active. So here white has even a better position in my view because whites problem with the king does not compensate for the lack of development and also having more species. And also here, what has these two central ponds? So here white has a better position. Other alternatives here, bishop Guido might be another idea. In order to bring the bishop to a three to block a check. And we see that this check is just one move, one active move for black. But now y can start dragging the Queen. For example, E5, if it's allowed, or even night D5 and McQueen normally will have to retreat because we will be attacking G7. So here in this position, developing the bishop in order to bring the rook and then the king to d1. So here we will be gasoline by hand. It's an interesting idea why it has other possible moves are moved that I wouldn't like a lot here is G3, although in a way, when I bring the King to the dual, here, black and try and move like H5 and tried to open lines against white skin. So this is not necessarily a bad move, but it's probably a riskier move. And again, I prefer to move a bishop or an ite instead of Upon. That's why the more D3 if it's not forced, I don't think that is the best moving their position. So if I go back to this position, when I spoke about the moment I take s5 here, I believe that is in fact better to take with the night. And after the four played these position which is more quiet, but it is fairly equal. Instead of plane here the move Bishop takes F2, which even though prevents White from canceling. What we'll get. A lot of other benefits, such as the centre or very active basis. 26. Summary of Castling: So it is wet. I will never understand about the importance of Gosling. We know that normally canceling greatly improves the safety of our King and also improves the activity of our rooks. Now we know exactly what to do whenever we can guess a long or a short. And also, we need to know how to deal with the situations in which we cannot castle, but we still need to find a safe haven for our king. So I'm waiting for you on the next section to keep on learning new opening ideas. 27. Intro - the Center in Chess: Hi, you probably heard that the center is very important. So in these sections would analyze the reasons for that. Also will introduce a very broad topic, which is the classification of the openings. And we see that this is very related to the sender. And finally, we see that sometimes our opponent or us we can give upon to gain control of the center. So the center is so important that we can even give material for that. So we'll study these, what we call gametes, the sacrifices, and we see how to play against them. So back of the chessboard. 28. Importance of the Center in Chess: Hi there. So why is this under so in bond plus follow and to highlight the sender here, which consists of the squares D4, D4, D5, and E5. So I'll start with a very simple idea. So how about we play the movie night? We have three here. And let's say that our opponent replies with nitric F6. And here went to improve the night by placing it on a central square. Here, since we don't have control of the center, then our portal would seem available, T6, and the night would be attacked. And here we already have a problem because if you move in the night to see for ten, the night might be attacked sooner or later with movies like B5, D5, or Bishop to S6. So basically the night is not stable there. Or if you play a move like night to D3, then here the night is block in this pond, which normally is good to release the Bishop or the queen. And if we go back then it is blood turned to move. And also these MOOC D6 already improved the activity of the bishop. So all in all, we couldn't control the sender here. Now if we took a somewhat similar position, then here it is y to play. So here we have a nice square on the sender, but also blood has a square on the sender. Here. What my play them of 95 maybe is not a very good move because we need to develop basically all of our other pieces. But sooner or later we might play a move like that because the night there is going to be much more stable than in the previous example. And if we take a look at this position, the center is symmetrical. But here what is putting some pressure on the centre with opponency for also these night might have an I square on E5 and this nightmare have a square nu four, although in this case, white can also take. But here it is like to play. Black might consider developing the night 06. This is not necessarily a bad move. But here we can see the difference that in this position, why does put him brush on the five? Whereas black is not putting pressure on before. The nineties antagonists before, but it is very well protected with the pon, that night and the Quinn. That's why this position, based on the pawn structure, might consider moves like night B27, which at first might not look very logical because it is blocking the bishop. But here, black might consider plane above like B6 and B7. Remember that bishops can be active even when they are far away from the center, because here, the Bishop of m7 might put pressure on the form. So as we can see in this case, ponds influenced the development of the night. Also here we might consider moves like c5 and then plane the night to see six. In this case, replicating whites idea, which is to put pressure on the center. So here, after taking on the four, then the night has more pressure on the form. While also here for sure before doing that, the black can castle. But since we're analyzing these position, I would also like to highlight that in this case, a move like detects E four does not look like a very good idea. Because here what would simply take the Upon. So basically here, black is helping develop. And also we are exchanging a central bond, which are normally the strongest bonds. Four upon, on S4. Having said that, that is not necessarily bad, but we might consider exchanging those bonds probably after a move like Bishop to D3 by white or Beach of T2, e2, where a white would waste a tempo. And then we may consider taken because in that case, we also open these diagonal after Ebola B6 are Bishop to B7. So again, this is just an example, but here we can see that everything is going around the center. So finally, if we go back to the initial position, the say that white plays a move like y4 because we wanted to occupy the center. I'm black plays bad moves like H6. Then we can play a more like d4, because normally occupying the center is the first strategy to control it. And here let's say that plays a move like A6. We already see that white has a significant advantage, again in the form of activity because we received an equation is active, although we don't have to develop it quickly. The bishop is active. This is active. Whereas Black basically can only develop a night even here after moves like night to F6 or night to 66, black has to think about movies like E5 or D5 attacking the nights. So all in all here, white has control of the center and a wide is ready better. So to make it simple, whatever we do on the center will basically define the future of the game. 29. Classification of Chess Openings: Okay, now we know how important in DC Center. And in fact the center also determines the name of the openings. So now we study how the classification of the opening works based on how black or white react on the sender. So in the starting position, White has 20 moves. That is eight possible Podemos, because why it has eight bonds, and those bonds can move one or two squares. And also white has tonight's moves hears, and tonight moves here. That makes a total of 20 moves. But as we'll see, the most logical moves in the opening, in the first move are not so many. So since it's important to have, I grew up on the center than it is normal for y to play a move like y4 or the four on the first move. So we start with the movie e4, which is also called the king spawn. And here black can reply again by trying to grab the sender or trying to control the sender. And the first natural reaction might be to play a move like e5 because we obtained y5. We also tried to control the Center on we prevent or tried to prevent black from blame the move before. So it looks like a very logical move. So in this case, since we have the two palms facing each other, the king spawn. That's why we call this opening that double kings spon opening a. Now, if black plays different from e5, all the other options will be called the asymmetrical king pawn because we don't have a symmetry. And here again, if Doug doesn't play E5, like has a lot of options. But the most popular options are S5. In fact, the move C5 is even more popular than Blaine E5, which is called the Sicilian defense. And here I want to clarify. The defenses are reactions by black. White opens the game. Lack reacts. That's a defense. Under Sicilian defense is in a way very similar to a five because also we went to port pressure on before and after. The Sicilian defense. Like has another option which is to play E6, which is called the French defense, which is an indirect way of plane. And the point is that after a move like default taken control of the center, which makes sense. Their blood plays M of like D5 to counter attack in the Center. For instance, his wife takes on D5, them like myTag with upon and having asymmetrical position. And in similar fashion. The third option is to place C6 and the body's thereafter d4, d5. If I takes, which is not necessary, then black can t With upon. So black has many other options, but these are the three most popular options when it comes to asymmetric allocating one. And here I wanna make a side note. Sometimes want to have this position with e4, e5 dispositional might be called open game. And whenever black replaced differently, for example, pain up over like C5. Then this may be called semi-open game. And I find this classification a bit confusing. So we're not going to use it because an open game is also a position in which you have opened files, rungs, or diagonals. And not necessarily when we play e4, e5, for example, will have an open position or a semi-open position. That all sounds a bit confusing. So that's why I won't use this classification. Instead. Wb that say nibble king pawn. Asymmetrical kickball sounds much easier to understand to me. Now again, if we check the second option, which in a way is also very logical because one drug by the sender. And here again, the first natural reply by black is debatable D5, which is called the double queens pawn opening. Or again, like my dry, something different. So on here, if black doesn't play D5, then black will try do something against the sender. So in this case, the most popular reply is the movie night to F6. These are called the Indian systems. And here, depending on how the game bubbles, like Complaint, many different Indian systems. So if white plays up of like C4 them overnight F6 is a prophylactic moves in a way because it prevents the move e4. So that's why white plays him of C4, trying to put present irregular and ascender. And after a move like E6, if Y developed cyanide for example. And after I'm overlay B6, then we have what we call the Queensland and defense. Or if white develops the other night after M of late night to s3, then black plays a move like visual before it's popular. Other alternatives definitely are possible. Para noun for wizard on the Indian defenses. This is their name. So Indian defense, again, the point is to put pressure on the snide, which is acted on the center. Also the move B6 inequality Indian. The point is to develop the bishop and to put pressure on the sender. So here why this overbearing descender? But black is trying to counter attack on the sender. This is in fact a more modern approach to chess. This is called hyper modern chess. Because in this case we can see that black is allowing white do take control of the centrism cases and trying to conduit jacket instead of E6 here, black conveyor move like G6, also developing the bishop on G7, which we call and ghetto in jazz. And after a movie like night to C3, planning to play for occupying the center. Then like Canada, counter attack on the centre with D5, which is what is called the groom for defense, or black gambler move like Bishop to G7, which is called the king's Indian defense. So just going back a little bit, all this defense is I'm talking about they belong to the Indian systems. So first the opening is defined by the first move. Overplay the move before. It is called the Queen's Spawn Game. And depending on what black replies, then we have another name. And this is kind of an ongoing process because then depending on what Black place, then we may have a defense. But then depending on what white blaze women have another variation. So here we start having a lot of naming some variation. In fact, I believe that there are over 1000 opening names, so would like memorizing that. But on a more serious note, this is not really important. What do we need to understand is what we play and the principals. So if I go back to initial position, then white can play E4 as the first move, the four as the second move. E4 is a bit more popular because in a sense, it activates more pieces, because it activates the queen and the bishop. Whereas the four activates the bishop and the Queen, but a little bit less. So that's why for is more popular. So y4 is the first MOOC, D4, the second move. And then we have other options which are much less popular but still played. The third is a move nine to F3 here, which is called the ready system. Again, this is a prophylactic move in a way we can see with developer night, but we also stop lab from playing the movie E5 or hear white complaining move C4, which is indirectly putting pressure on the sender, which is called the English opening. So if I go back on the initial position, by far, the most core moves are E1, E4, or the move D4. And then the other less common moves are the movie night to have three, which is called the ready system. And then they move C4, which is called the English opening, is another common move. And all the other remaining moves with the replay B3 or g3, or any other move, they are just called Uncommon openings. 30. Gambits to Dominate the Center: Hi there. It is now time to talk about gametes to improve the central domination. One, what's a gamete? A gamete is an opening in which material is sacrificed. When we spoke about development, we spoke about the moral gambit, which is an example of a gamete in which white gives material to get development in exchange. So let me remind you. It was our kings spon, game and then associated on defense. And here comes the move before and after Black takes upon. Then instead of taking back the bond with the Quinn, then here white pays above S3. The point being that if we take, we deal with the night and we start developing pieces much more quickly than black. And there we also spoke about the idea of giving back the material in order to gain back development. In that case, it was play moves like night to F6 or D3. And here we see that we can use a similar principle if we wanted to. So since there are lots of openings, I will focus on the most popular gametes that aim to gain central elimination. And by far the two most popular gametes in this case are the kings gambit and the Queensland mid. And let me give you two general notes. First is that the Kinsey gambit is not normally very sound, but the Queen's gambit is perfectly playable. And secondly is that we would need not one but several courses to explain each of them. So here I will just provide some practical tips on how to play them. So now we go to the kings, the ambit. So we start with e4, so we have our king Spawn Game. And if blood group based with the move Y5 here comes above F4, okay, so the point of these gametes is to gain control of the center. So the idea is that after Black takes here, then white has two central ponds and black has only one. So black is upon up, but quite normally will have more control and ascender. So sooner or later while my play a move like D4 and have a nice central nomination. So the main point here is that the sender is so important that sometimes it is worth upon. And the main idea why they kings gambit is not very sound is at the King, is still open here. For instance, even here I'm over like window edge four is objectively, I would move because here white normally has very few squares for the king. Here king into is a most common reply. But then here y will try to play night F3 attack the queen, and then try to take the bone and keep the sander. So this position, although it is objectively good for black, it is very complicated. And here comes another important note that when we play these positions, our opponent by baby bird, so we need to be very careful. That is why here we might consider alternatives such as a movie like Bishop C5, which develops. So normally development is great. So I like this model. And here, why do we normally also develop and put pressure on the center would have move like night, we have three here. The point is that if y takes on a five, then here Queen H4 is very strong. So we see that this is our problem, a regular problem that Y has with the king. And if a play while King Abdul would lead to checkmate. And if white plays G3, then queen takes y4 is very strong because we give a check and we attack the rook. So this is winning for black. That's why neither three is a logical move. And here we pay them of D6. Again, we tried to keep the center. And again, like cannot take only five because we have the same idea of when h four check. So here white again has many options, but let's analyze the most critical. One of them is c3. And again here I like developing mobile eye nine F6 and after d4 because white wants to occupy the center. And after digging into four, like has many options, but I like Bishop to be six because if white ends up pushing D5, then this diagonal will open. So we're looking at the king there. I'm like has a perfectly good position. For instance, if web-based E5 keeps on trying to be aggressive. But here we are going to have over like 95. And after vision of C4, which developed and attacks and denied, We can take only five, and after taking only five, then we can simply keep on developing. So what I like about these ideas that blacks develops. So black is perfectly fine. Even if white tries to adapt with movies like nitrogen five, then we're going to continue developing. So black is perfectly fine here. If I takes, then we just take. This poem might be a bit weak, but again, we have pressure here. We will play a move. Maybe it would like when D7 and gas along because the king is safe, they're guarded by all of his pieces. And if we go back instead of C3, then if white plays a move like night to s3, then we're going to continue with them offline knitr 66. So lag is so fine that even here we might consider payable that night to F6. Even if we give this bond now 25, then black will get very good development. But if you want to keep it simple than nice, N6 is perfectly fine. And again, we, we did a course or more to lyse their kings gambit. But here I just wanted to tell you that we follow principles. If we develop, then we get a perfectly fine position and we don't need to accept this sacrifice. And we analyze the second gambit, which is actually the most popular gamete of all, which is after d4, d5. White plays the move C4. These more voxel is very logical. And one of the point is that if a player move like night to s3, then y does not put in a lot of pressure on the sender here. Because like my play mosaic C6H6 if needed. So it is much better for white to reach this position would upon on S4 because we have an additional piece putting pressure on D5. So the Queen's gamete is perfectly sound, so and after mood like C4, here, black has many replies and the most popular reply is also not to take the bone and to play the movie E6, which leads to the Quincy gambit declined. Or to play a movie like C6, which is called the slab defense. And also here the main point is that if tactics, which is a perfectly payable move, but not the most popular move, then white will gain the sender sooner or later. When my dry move like nitrogen three. Also before it's possible, we have lots of lines here. And if like continuous developing now, or what is logical then after e3, then this bond will sooner or later fall. Because if we try to keep it at all cost, then that even might become riskier after white contour attacks. Then they say that we want to support upon which C6. Then we'll just take here. And after a movie like B3, then all these structures collapsing. For instance, if black takes upon here, then we'll just take a bond with Jack. On again, this bond will fall and white is developing and getting the sender. So this is not going well for black. Instead here of black can play many other moves like E6, which cosmological to develop the bishop and two castle. So here the game continues and wide will try to claim an advantage with this two points against one. So when allies to most popular gametes to gain central elimination. And these are the kings gambit and the Quincy gambit. Mckinsey gambit is very aggressive, very risky. But the Quincy I'm, it is quite sound, quite solid. And I suggest that if you're not well, the bird just follow the principles that we learned. And normally you would get a good position. But if you're also will be burnt, you can definitely accept these gambits, but always keeping in mind not to be greedy in the opening, not to be too greedy, but when together, I could position rather than a material advantage. 31. Activity - Center: Hi again, unless now practice with a few precisions. So in this first position, let's imagine that we're playing here as black and hear what normally would develop with nitrile F3 or Bishop to S4 In order to Castle later. But let's imagine that here white plays a move, G4, which is quite aggressive because the more plants to play D5 and attack the night. So I would like to ask you here, how would you play in this position? And let me give you a hint. Tried to counter attack in this position. And here in the second position, Black Company many moves. For example, black can take on D5 and then play them of D6. But there's an idea here to play the movie B5, which seems a bit strange because black is task given upon. But one of the ideas is to take on the five after Y takes on B5. Black can take on the five with the bone. But before taking on B5, why can drive taken on E6 first? So here would like to ask you, what would be Blacks main idea if white takes on E6? And let me give you a hint, think about gaining central nomination. 32. Solution - Center: Alright, so in the first position, the G4 by white would really break opening principles. And it wouldn't be a very strong move. But on the other hand, we might feel a bit intimidated if our opponent plays emulate that. And here in fact, even a movie like Bishop to C5 or developing move after G5. The main point is that the night has to retreat because the night kinda go to default. But even here after nitrogen, black can bring the night back to seven. But in any case, wide achieved his ego. Another possible move would be to play the move H6, trying to stop this idea. But since this idea is not very strong, this is not strictly necessary. It is not a bad move, but it is not necessary to play these. Thus why I asked you to try to find any conduit jacket moves. So if you thought about the moves, the five or edge five, well then the movie H5, Actually it is not the strongest because after the move G5, although we can bring the nitrogen four, then here, after a movie like H3 denied, doesn't have any goods cross drew tweet on here possibly like would have to try to sacrifice a night for two bonds, trying to get some attack on wise king. But this is really complicated matters and it is not even clear if black has compensation here for the piece. So this is definitely unnecessary. On the other hand, I really like the move, the five, It is a good move in this particular position. And from a general point of view, this is a very important idea that whenever one side place on one side of the board, it is very natural to try to find kinda play on other side of the war. So in this case, why displayed on the king's side? So black is trying to find can-do play on the sender. So the move of the five already attacks these Pantone for and also these porn on GA4GH. So he after the MOOC D5, black has a perfectly fine position. For example, quite cannot play the more d5, which was the original plan because here lie would take only four. And after digging on the five here, black and either take the spot on the five with the night or even dig this PRNG for normally is better to take central bonds, but in both cases, black has a perfectly good position. So this mode G4 is really not good for white. The second position is quite uninteresting gambit. It is not very popular, definitely not as popular as the queen's gambit, For example. Here we have an Indian defense and the idea is to gain control of the sender. Here after the MOOC B5. First of all, why does not forced to take these bond? In fact, white can play a move like BCM2835, which is quite interesting because if blood takes on S4, then would just pay night to S3 and then E4. And it does actually wide the one who is having control of the sender. So this is a very good alternative to taking on E6. So here we again see the value of development and gaining control of the center even if we give material. Instead here taking only six is perfectly possible. Here. Black, first of all, doesn't wander desc here and s4 because after taking on F7, here, black has trade with the Qing. Unlike cannot castle anymore. And here y already has a great position. For example, here what can play a movie like y4, stopping D5 ideas like an uptake these porn because you have to remove Quinta D5. We give a check and we get a lot of material so we see how black skiing is misplaced There also here dig when the bond would be a bad idea because like an exchange wins first and then take this bottom B5 and hear what it has an extra proton. And I don't see any compensation for black. Instead hear blacks main idea is to deal with the F pawn. And after white takes the spawner, then here labeled they D5. And we see how black has more bonds center and also has a nice central elimination for example, here, it is not easy for a wide to play the movie for. So here black has a decent conversation for the bond, for example, the game my continued G3. And here black would develop the basis. This is not a force line just to show you how both sides would develop. And here lag would have I would position. They drawn my drive to push the bone and gain more space on the centre. And we also see how black has slightly more development. And this bottom B5 is not doing much. So all in all, black has decent conversation here. 33. Outro - the Center in Chess: So let's summarize what we learned in this section. We'll learn about the importance of the center and how the game basically revolves around the center. Now we know the most common openings and the most common gametes to gain control of the center. We spoke about lots of gains, but here I want to remind you that it is not important to memorize names for the sake of fate. What we really want to learn about in this course is how to think, how to develop a system of thinking and learn principles, how to apply them. So you might definitely play a game without knowing the name of the opening. Human play the position. If you apply principles, you might get a great position. So remember, it is much better to know how to think than to memorize. So it is time to move forward to the next section. So I'll see you in the next video. 34. Intro - Breaking Chess Principles: Welcome again. So in this section, we're going to see what happens whenever our opponent plays out from which is completely different to what we learned. So we learned test principles. We know that they are very important. But on the other hand, what makes the game of chess interesting is that sometimes we can break this principles or some desert complete something completely different. So we need to know what to do. In these cases. We need to know how to play. We need to know what you have to do, something specific against that or not. So this is definitely one of the most important sections. So let's get started. 35. Can You Move a Piece Twice in the Opening?: Okay, so we spoke about the importance of development and how the opening stage finishes when we develop all of our pieces. So normally moving a piece twice does not make a lot of sense because we want to first develop the other pieces. So for instance, in this position that we had when we analyzed the importance of the center, I spoke about a movie like night V5. And here the move doesn't make a lot of sense because this night cam easily attacked and help black develop. Also, white has all the other pieces waiting to be developed. So these move here, moving a piece twice doesn't make any sense at all. When I first spoke about the importance of the opening stage, we had disposition played by a former world champion and atomic Rprof. And here carpet flayed him overnight to h5. So here, let me clarify that this is more playable, much more playable. At least here the night adapts another piece. So here we have a piece Moon twice, but at least it's attacking. But on the other hand, I spoke that this move is quite risky because it worsens the position of the night. Because the night closer to the center is much better. And also still we have lots of pieces to develop. So does y, unless we know this position very well, I would suggest to pay other moves here as black. So here black and play a move like DCX makes more sense. If black is scared of some E5 ideas that were attacked, denied, and then just write to develop normally with movies like Bishop to E7 and Castle. Also black might try to develop here the bishop and here, even if white has a move like before, then we're going to try to play Bishop to the four and the five. This is a bit more complicated but still playable. And here again, we develop pieces. So this looks much simpler to me. And here when carpet flayed him overnight, H5, the night is attacking the bishop. So here white. Since black Broca principle here, why it is in a way forced to break the visible. We could defend the bishop. But you know, this looks better than the night here. We could define it with a movie like D3. But that's why here White played him obese U233, which looks great because OK, we brought the principle in a way we're forced to break the principle. But here the bishop still looks quite active, whereas the night is much worse here. So both white and black broker Principle. But in the end, we see that Y stands a bit better because the visual is more active than the night, so the position can continue. But here let me remind you that like made a very bad move with Bishop 2D6 and after Quinn the one, then what one apiece. So instead, it will be more logical to continue developing. When a mobile IP shoved z5, we don't lose apiece and we continue the game. So the overnight to H5 breaks principle. It is not very bad, but it is definitely risky. Here we have another position. It is theoretical position. And here black praise him, move B5, and it is wise to play. So here, black plans to play the MOOC before, which would attack the Tonight's. So that's why here white is pretty much forced to break this open in principle and play a move like night 25. Or why can play Bishop takes a fixed first and then play nitrogen five. So this case is a bit similar like the previous case. We are forced to break the principle because black has a big threat of women apiece. So we break this principle, I would move up is twice. But on the other hand, we see that white has three pieces developed. A law does not, is not very well-developed, then I donate three, but black has to be developed and Y3, so we move up, it's twice, but we are still not behind the development. So in this case, moving a piece twice is perfectly logical. And here we have a position, it is Y to play. This is also a theoretical position. This is called the London System. So just to briefly introduce you to these london system, it is Queen Spawn Game. So why played him of D4? And then white will develop the bishop to a four. So here, move forward to the current position. And here, by the way, the opening stages almost over because white develop all the minor pieces and the rooks are almost connected. So here what could consider moves like developing a queen to connect the rooks. But also in this position, white can move up to H two. This is not the most popular move here. A4 is quite interesting because one of the ideas is to open the file and I'd give it a rook. So we're already activated. Most of the business now has jumped to activate the rooks are the quinn. But the bishop to H2 is also quite logical and interesting. So here we're moving a piece twice, but on the other hand, we're almost out of the opening. So it doesn't break laws of principles. But also here, black, sooner or later we'll plan to counter attack on the center. Because why it has a very strong center. And for that, these Bishop might become under attack. Japan u4 would moves like night to H5 or possibly night to D5 and then support is advance. So that's why here white anticipates. So this is a prophylactic move. So that's why what can play a movie like Bishop to H2. But Assad is not a force move, but it's quite a playable move. So to conclude, is just bad to move a piece twice. So most of the cases is not a good idea. But in some cases, we are forced to do it because our pieces are attacked. So it's not bad at all. And in some cases, quite optional and quite interesting, like in this last case that we check. 36. Making Too Many Pawn Moves in the Opening: Hi again. And now we'll study the idea of making too many pawn moves in the opening. So just to rewind a little bit, we'll discuss the normally wanted develop minor pieces if possible, such as night or bishops. But also that sometimes this is not possible because if we try to put an i on the sender, for example, then the opponent can't get away with a bond. So also that ponds, they can be developed if they go closer to the center, does much better. So anyone that is central or close to the center, let's say they see your f bonds. They sometimes can be moved and that's okay. So for example, check this idea that if a play E4 and our opponent place mosaic H6 and after the four A6, we already have an advantage because moving cerebral ponds is normally good. We may even consider it as a developing more of about other moves. They are not very good if we can move a minor piece. So all other things being equal, development apiece, a minor piece is much better than developing upon. For the simple reason that they are more active phases of the control, more squares than bond. Now I wanna go back to this position, what we discussed about moving a piece twice. So here it was y to play, and white has no move, does night or y can take on F6 and then move the night. But we can see that here, like made a lot of pawn moves. So we'll analyze this position from the beginning. So we got this position when white plate E4, which is their king spawn opening, luck played C5, which is the Sicilian defense. And after night We have three, which is a developing move than like also develops a night. And after d4, whites try to cuddle sender, lacked takes y takes Black develops an ICT. And why develops, right? So, so far everything looks very logical. But now black starts making lots of pawn moves. The first one is the move E5. And this will lead to a variation. So we aren't necessarily on defense. Aberration is part of the silane defense, which is called the special variation. And here, white plays the move Knight to B5, which is logical because we wanted to play 96 tech lab would take then rotate with the quinn. So that's why normally black braces move these x. So here white develops and luck plays a move A6. So these Knight was a bit annoying, so we attack it. Adhere again, will pay me five. So in the last eight moves, blood played, six pawn moves obey. But we see that this point moves, they have Algonquin purpose. So the first one is C5, which makes it harder for white to play. D for. The second move is TIGR and d4. So here we exchange the sea Pawn for the div for points, or normally this is, I will deal a good exchange for black. And then here comes the move e5. They move E5 has advantages and disadvantages. Todd, the first advantage is that we attack an ICT. Also, we put pressure on the center. So this normally is great. On the other hand, we weaken this square D5. So white will try to put a piece there. And after 95, By the way, exchanging is normally not very good because then like intake and now black, that will pay D5 and have good control of the sender. And after 95, D6 is a logical move because we stopped 96. Other ps can be played by D6 is the main move. And after being up to G5, then A6 again, attacks denied. And after B5. So we have a threat and also we limit these night a lot. So this movie is very concrete, has objectives. That's why black can manage to play 6 moves out of eight moves here. Now I want to check another position if played before, we have the Queen's been opening, like replace with D5, which is a common reply. And after S4. We also saw this idea of putting bridge on the sender is gambit. And after C6, which is one of the many options, like can also play E6. Also this MOOC has the purpose because we want to support the center. If Y takes, then we will just take with Upon instead, if we wanted to defend that point with a mobile 99 F6, then why would take and this would be normally I would exchange for wide because why would exchange a C porn for a central bone? And he went after white takes, for example, with the night. Then after e4 we see that we start controlling the sender. Softer C6. Why develops? Then black can also develop an afternoon to s3. Then black can make another point, which is E6 to support the center. So black is going to have a strong constructor there. And after e3 here, normally the most logical moves are to develop either the Bishop or the night, and they be D7. But also a more modern approach to this position is to play A6, which is called the J Bannon covariation in the slab. And this movie six doesn't look, we're logical, but it has several ideas. And one of them is, now we might plan to play on S4, unsupported upon, but also we might even try to play B5 directly to put pressure on this point, because this point actually is putting pressure on white center. So that's why you want to counter attack. Again, A6 is not the common move here, and we see that blood played lots of pawn moves instead of developing. But this is playable. In any case, normally black will continue developing later on and we stop making all this. Pawn moves will start blade moves a bishop to before bishop 2D6 and gasoline. And normally the night will come to this n. So in the last two position that will discuss this pawn moves, they had specific purposes. So making palm moves for the sake of it is not a good idea. Let me illustrate with another example. Let's say we play P45, 9396. Let's say that y develops, unblock starts making random pawn moves like H6 will develop. And A6. Laughter, why castles? White is already having possibly some serious advantage. D4 is coming. Maybe black will have to stop it with Bishop to S5. But if law continues with the strategy of plain pawn moves, then white can either break on the sender or plane at age four and start attacking the Qin, which is in the center. So in this case, Megan bone moves is not a good strategy at all. So making several pawn moves in an opening can be done in very specific openings, but only if these moves have a purpose. But having said that, this is normally an exception and not the rule. So I don't suggest that we do it. E104 opponent does that, then will just follow principles. Developing a nominee will get a great position. 37. When You Should Not Castle: Okay. So when we spoke about Kosslyn, who spoke at the main goal of cancelling is to bring safety to the King. But in some exceptional cases, canceling does not bring safer drinking, but it's even dangerous for the gain. So we should always analyze this specific position and double-check that gasoline is a good idea or not. Let's start with an example. So in this position it is like to play and hear. Blood just goes for canceling with the move measure B7 than white. My belay night were three to develop. And after casting. Then why do I try an interesting move, h4? And the point is that the if block now ones to develop with an overlay nitrosyl SEX OR S5. Then white has a very powerful move, which is above Bishop takes age seven. And then if black takes the obese than 95 is very strong. And if lacked takes the night after age, takes D5, can G8. When H5, we plan to check rate here. And after F5 and we have G6 and the King will not escape when it's seven or queen to age eight is Jack made like has other moves after 95 check. But all of them lead to an advantage for wide, for example, again just six. Then we have H5 sacrificing another piece. And this King is very weak here. And after maybe three, King F5, Queen of three is ten. So regardless of all the variations, we see that the king was under attack here after gasoline. And the main point is that in this position, this bishop is attacking. This night, is getting into the game quickly under Queen as well. Not to mention the rook after Jake energy five. So all of the business are looking directly or indirectly. I became, whereas the king herniate done in much safer as why this position normally Blackboard counter attack on the center, so it has a small space advantage. So here, normally black counterattacks in the center. And after white tries to keep the center, like develops a night. After 92 would take under black again, continuous contradicting the center. And only after we see that like has improved its position, neither three Bishop D6, and only then we can consider gasoline because here we see that this night is defending our age seven. Like has the business more coordinated? By the way, the sacrifice 97 is very typical for in this case, black should not castle or delay gasoline. Here we have a theoretical position. The position is extremely complicated, so we could spend many, many hours unless it, and here it is, black to play. Anomaly would try to gasoline. So let's start analyzing long Castle, which is the legal move. And here we could see that what can immediately started back in or opening lines against the king would be five. So black skin doesn't look safer. There. Now if we try to Castle short by playing Misha P7. And why do I try a five? And after casting, we see that y has lots of bonds login the king. So here we can dry plane and aggressive move like G5 on launch, what we call upon storm. And here the idea is to oboe lines against the king for the rocks or the Queen. And after tries to close the position with h5, then G6 is very strong. The point is that if we take here, then nine takes E6 is very strong. So although the position is very complex, we would say that by process of elimination, it is probably better to keep the king on the sender. So here normally language start login for countably. Here the moment I B6 is very interesting. Looking at the spawn trying to jam to C4, also the c file, not that we didn't gasoline is open for the ROCC. So we can put pressure on C2. And the position is very complex. But here, not gasoline is better. But also there are other cases in which gasoline is more optional. So in this position, it is also black to play and the queens have been exchanged on the nine most have been played. Black skin is safe. Black would castle and makes lot of sense as well. But also blood might consider liking to E7. And the point is that if we keep on exchange in pieces, then this king is going to be more active here because it's disclosed to the centre. Now I wanted to show you this position are normally in this position. What would they like to S3 night to have three develop. But an idea is to play the move h four. In fact, this was played between two very strong players. This is not conventional at all. But one of the ideas is to open the.h file and have an active group on the HFile. And maybe the king will come to F1 or g1 after white move the pieces. Or maybe because long. But here what is not gasoline? This is not necessarily good for white, but it's something different. And after 792, C3, then cancelling, I think is perfectly possible. But here we will make wise plan more logical. So that's why we could try solving different delaying Gosling in order to play against the opponents plan. So here in this position by play the movie D5. And this is a typical idea. When someone plays on one side of the board, we normally can play on the other side of the board. And in the end, black castle, but only 25 moves later, but black still got a perfectly good position. So just to conclude, remember that safety is the main point, not gasping. So in some rare cases, counseling is about unwilling to avoid it. But these are very exceptional cases. In most cases just double-check if there is no direct attack then guzzling integral idea. And in some cases, when there's no danger for the king, cancelling is optional. 38. When You Can Give Away the Center: Great. So we spoke about the many benefits of having a strong center. And just to remind you, we started with this position. If a play E4 and our opponent plays nonsensical moves like age, sex, and after d4, A6, where you get more activity, we're ready, get a better position. But how about if our opponent plays something in between? Let's see, after d4, replay 96 and after E4, DCX, nine of three, E6 night to S3 on night F6. So we're football a wide, we dominate the sender will develop the nights. This makes lots of sense. Unblock, played something similar but gave away the sender. So at least here, black developed the Tonight's. And these pawn moves are central pawn moves. So maybe the bishops can be developed a little bit later. So we, I would say White has an advantage, a slight advantage maybe. But at least this makes more sense, even though black gives a center, lag is developing. That's why there are some openings or some defenses that they are normally called hyper modern defenses in which their center is given, but either decide that gives us enter develops or look for a countably. So we're going to see a few of them. One of them is the periods defense. After e4, the king's been opening, not plausible. D6, so black gives away the center. And after nine F6, we develop an attack before. So this move can be bad at night to C3 to defend. Then instead of playing E6, which is a bit passive, then by the way here blood convey the movie five. So just trying to fight for the center, this is a perfectly logical move. But instead of Y5 here, black can play the movie G6, and we'd get the periods defense. And the idea here, white has many options, but if white decided to develop, then black will play the movies up to G7. So if Tn K2 in the bishop, remember that the bishop can be quite active here. And one of the ideas is to put pressure on the center with the bishop. And later on with movies AX5, nice E6. Sometimes Bishop might come to G4 to exchange the bishop forties night, which is controlling the sander. So all in all black is given the center but is organ for active kind of lay. This is not the most popular option to play against E4, but it's an option and it can be playable. Another idea, in this case we have queens bone opening, and this is an Indian system. It's the kings in the defense. And here, instead of taking on the four which can be played, black can play the movie night to C6. And here the most common replaced by D5. So with them overnight to C6, black is inviting White to occupy more space on the sender. To Genspace advantage, which normally would lead to an advantage and after night V7. So White Houses base advantage on the centre and also white will try and to gain space advantage on the coincide with S5. Then. The bishop by come to E3, the rope to C1, the night to be five. Basically why we try to dominate on their coincide. On the other hand, here, black will try to gain counter play against the center. So this nightmare cam to age five or eight normally or the seven. And after a five legged worldwide counterattack in the sender. Alternatively, like my also tried to play the move F4 and then launch upon storm, what we call upon storm, after G5, H5, D4, and tried to attack white cane. So here we see that white space advantage will gain in space advantage in coincide. But black will have the king side and we'll try to attack there. These are very common defense that Keynesian and events is extremely sharp, so it is quite playable. Another idea to give away the center is the Eliakim defense. So after the movie y4, here we spoke that the most common replies, C5, F5. But the movement I do F6, which is called the Aloha defense, can be played as well. And these invite white to attack the night after E5. And here black normally follows up with night to D5. And after d4, white occupies the center. But we see that black stars counter attack in the center straight away with them of D6. And if white wants to continue attacking the night with S4, then 96-well plate. And if y twice to support the center at any cost after F4, then black normally takes here. And after night to C6. Here the five is not possible because we take the pawn measure B3 and B4, B5. So here I want to show the position. White has space advantage on the sender, has ponds in the center. But on the other hand, like has more development. And also black will start counterattack in descender here with the rook and the queen to put more pressure on the form. May also play E6 and then F6. If I go back a few moves, let me say that C4 is not forced here. White may also follow general principles. Play more quietly. And play 93 Bishop E2, Castle. This option and the option of latency 44. Both are possible. This object is quieter and also after night F6, OK, E5 is the more popular movement, but we may also play a developing move, defending upon with night to C3. Although in this case, black would play D5 to counterattack in the center. So in this case, why would not get this central advantage? So given away the center is not bad if we or our opponent can put pressure on it. Or if we have some other form of underplay. For instance, in the Keynesian Indian whisperer, how black would put pressure on it with a five and maybe a four and gain space advantage on either side of the board, on the king's hat in this case. And last but not least, we should not stay behind the development. This is very important. So we analyzed several openings that give away the sender, not all of them. But I hope that you got the main point. 39. How to Deal With Unconventional Openings?: What shall we do whenever we face and commercial openings or an unconventional opening play? First, I want to remind that the most core moves in the opening, our E4 or default, because we want to occupy this under. But we also spoke that the move of C4, which is called the English opening, is also quite playable. So watch I will be here as black. So if we follow principles, then we have several moves that we can play here. But the most common is to bathe them overnight to F6. And after the moon night to F6. If white tries to again follow principles, what we normally try to occupy the center. So in this position, white would normally play the movie before. And after the move. D4 will reach a familiar position, which is an Indian system. But we'll reach it differently because why played first they move C4 and then the MOOC D4. And here I will introduce a term which is called two transpose. We say that we transpose into an Indian system. So this is very common inches. Sometimes we might reach a similar position, but playing very different movies in the beginning. Instead of the four wide definitely can play other moves like night to S3. Three are the most logical to develop. Or white can place something completely different. In any case, if a player as black, we will also follow principles undeveloped. Also other alternatives. Instead of nine F6, we could play the movie E6. This might look a bit strange, but the point is that if white plays the same move, d4, then after d5 will reach our Queensland blood. But we could also try another very logical move, which is the move E5, because when talk about the sender. And then we have, normally we're here, we have appear English opening. Here I will discuss about the main idea of these openings. But if we wanted to cover all the English opening similar to the Quincy gamete or the Kinsey ambit, we would need a full course or even more. But the main point is that here we will develop as black. Normally. Sometimes a bishop comes to before if the night goes to S3 and just play a game, or we got dynein F6 to transpose into an Indian system. I also spoke that the movement I2, I3 is fairly common after E4 and D4. And this is called the ready system. But here, like can play again many different modes following the same principles. Nine F6 is one of them. And now we've White goes back to the idea of occupying the center plane. The four A4 is not possible because the night would take upon. And then we might reach either an Indian system or we might go back to the W queens bone. Or after 1903 when my play D5, trying to occupy the center. And again, normally hear white might try to play the four to occupy the center. Now white can play different ideas here for sure. For instance, sometimes the bonds go to d3 and then wide-field ketosis Bishop. And this would be similar to, to the kings in the defense that we analyzed previously. We'll be paying these defense being a tempo up because white is being first. But again, this is not extremely dangerous for black. So black will normally also develop play night F6, C5, C6, and try to play E5 and get a good position. Now, white still has lots of moves. By the other remaining moves that are played more often are the move G3 and the moon B3. The mood G3, we contribute similarly to 93. We can play the F5, F6. And we can transpose to similar lines depending on what a white plays default or not. And the B3 is more original, so we'll get more original play. But it is not particularly dangerous for black, are normally black here will occupy the sender with E5 or D5. So the MOOC B3 is interesting to play something different because the move once to activate the bishop. Normally, as we discussed when we spoke about development. Nice tended will first, but here what we'll get the bishop to be due to a very good Square trying to dominate these diagonal. So the movie perfectly logical, but block will have no particular problems here. The other remaining moves are definitely not dangerous for black. Let's say that y plays the move E3 than normalised hydroelectric over 24 is where active. Or if y develops the knight to a side of the board, let's say at night to h3, this MOOC doesn't make a lot of sense, so we can continue just plain normal tests, e4, e5. And here I want to clarify something. We're not going to win the game because why placed them overnight to h3? So normally white twice to get an advantage because white moves first. So white gets more active first. So we avoid plays are dubious move or a bad move. Normally black will equalize easily, but we should not expect to gain and advantage. What plays one dubious move? Maybe if white plays loss of Dewey's moves or bad moves, then we can start seeing in a feminine advantage, but not only because of one move. Now if we check it from white side, let's say that we play E4, which is the most common move. With forward that making sensors moves normally will get wide and advantage. For instance, we saw this idea of ln H6 before an A6. And similarly if lactase above, that doesn't make any sense, let's say night H6, then we will just develop. So we don't need to try to punish straight away about local move. We will just develop and in the end, the space will look bad. It will not have any square root to go. It will not do anything there. And here I want to make a difference between unconventional moves that are bad or less popular moves that have an objective. For instance, in this position when we analyze the Moraga ambit. So here, normally quite we continue with Nia three or night to S3. But we also analyze these gamete. So this is not the most common play, but it has a goal, which is a pawn sacrifice to activate whitespaces. So to conclude, whenever you face unconventional play, chess, ask yourself if your opponent has a specific goal or a specific threat. If they move, doesn't have any goal, then would just follow principles and we'll get a great position. But if the move has a specific goal that we might think about taking concrete actions and even in some cases, Game by material, like in this Gabby that we analyzed. 40. Understanding Other Sacrifices in Chess: Hi there. And now I will introduce about other types of sacrifices. So first let me say that sacrifices is a very broad topic and that you also check a few types of sacrifices. And now I would like to check more advanced sacrifices. So I'm very happy that we can check advanced content that is even hard to analyze for the best players. But the main point here will be to understand the logic behind the sacrifices. So going back, I want to remind that reject a few types of sacrifices. One of them was a sacrifice to gain development advantage. And we saw the moral gambit as one example of that. Where white gives upon. And if that takes, then white will develop the night wide already has a lot of activity, whereas black has all the pieces stain on the first rank. I also spoke about gametes to gain control of the center. And the most common of that is the Quincy gambit. So black takes back is not forced, but if black takes than white might sooner or later try to occupy the center. So why it is given material but gaining control of the center. I spoke about the rare cases in which not gasoline is good. Then we saw this much of sacrifice in which what gets a willing attack. And here's where I want to mention the main bone of the sacrifices, which not strangely relates to the most important idea about the game, which is activity. Because when I spoke about gaining development with definitely gained activity, when we gained control of the center, we also gain more activity because we have more space. And for example here, why does a Dunkin, so I spoke that white has lots of pieces looking at the king. So in this mainline were wide takes. And then white gives Jack made. We also see that these checkmate translates into basically more activity on the king's side, which is where we checkmate the king. So now let's see more advanced sacrifices. Again, I'm happy that we can check this deeper ideas. But more importantly, I'd like to make sure that we understand the sacrifices. Here's a very original sacrifice which is played in the Eliakim defense. So after the kings, but opening them overnight to F6, we already checked these opening and we spoke that normally wide will continue with the movie five. But I also mentioned this MOOC, night to C3 to develop. And after the move the five, which is the logical reply to counterattack and descender. White normally Basie more E5. And after night FC7. First of all here taking the bone would not lead to much because blood would take back the bond. So here the most logical move is to continue with D for trying to build up on the sender. But here, white has a very interesting move. Not the most common move, but it's still very interesting. And I like to mention it, which is the move E6. So this normally wouldn't make a lot of sense because we give a central bond which is powerful. And after blood takes, then why plausibility for so we see that wide gave away assembled porn and also gave black and other central bond. So this wouldn't make a lot of sense. But logic behind it is that why do we have good control of the central squares, even though Why doesn't have bonds? Why we'll try to put a piece there. And also it is very hard for blood to develop the pieces, especially the bishops. So we see that these bishops here, 1.5, uneasy, damn developing. It would take a lot of temping to develop. So that's why white gives upon. But white gets lots of space for the PCs. And since it will take a lot of time for black to develop, white will normally gain a development advantage. And as we know, development advantage translates into greater activity. So the logic behind here is also the most Report idea, which is activity. Also a deeper idea here is that if black develops, for instance, with getX and Bishop, G7, fee and Cato and the bishop, which looks like the normal development for the bishop. Then white may also try to launch an attack, would age foreign H5 and Bishop 23, trying to open lines against black skin. So the sacrifice is interested in Bastille. Black can normally get a good position with aggregate play and in similar fashion, like sometimes even Gibbs upon paying C5 and 20 to gain back development. So using the same logic, care about getting a good position rather than getting a material advantage. And our idea that I'd like to mention, which is very common is the exchange sacrifice and exchange sacrifices given Iraq for a bishop or a night. There are lots of types of exchange sacrifices to attack, to gain squares. So I'll take one of them, which is pretty amazing. In this position, blood played the movement I2C five. And here, there, I guess part of who is a former world champion played the amazing move, rook takes B7. So before analyzing the move, we see that these night looks great there. This bishop is putting pressure on these nitrogens. D5, which is normally white. Space in the position is a more advanced, is stable. The night decentralized, we spoke about 80 of having night centralized. And also the ROC here normally doesn't look very well because it can be easily attacked by weaker pieces, such as bonds with move like A5. So that's why Caspar off gave away his wall space. One of blacks by species, which is a Bishop. And then after the night took, White played that come before, which controls the night. So the night was doing great on S5 And now is very miserable on B7 because basically doesn't have squares, it cannot jump here, here. This point here does allow black to improve the night. So it is right now, it was probably the best piece, one of the best business now is the war space. This is a very deep sacrifice, but here White got excellent compensation, then continued improving his basis with nitrate three nitrosyl for putting pressure on this bond and even won the game. And the final sacrifice that I wanted to check is a very common theoretical position. And hear what plays the move C3 to continue with the four. So to gain control of the sender. And here black and reply with the move D6 to try to keep the center, which is very logical. But he also blackened Brady move d5, which might look strange because after taken on D5 and dignity five, this bond is given away. So y can take only five. And after taking only five, roped X.25, White got an extra central bond. But after the move C6, which is the most common here, black has a lot of compensation because black would continue with Bishop 2D6. And the Queen my normally come to the King side. And as we see, black is much more developed. So even though black gave away a central poem, black gain development. Also we see that white will have to take quite some time to develop the night because the night cannot jump to the two or S3. And if we move forward a few moves. So white place before which is logical, ancestor and old barn and develop mashup DCX attacking a rook. Rook y1, coordinate for G3. This bone was attacked when edge three, white here, normally continuous with the more visual U233. As I said, this is a very theoretical position. There are many options here. Anomaly, lie will continue with the vision of duty for. But I also want to say that even if blood 2C here and three after Y takes, let's say with the rook. Then also hear black would have good compensation. Because here, like as these 2B shops that are very reactive and white has these night still develop? And this is another common form of compensation of sacrifice, which is to give upon to have the bishop pair as black has in an open position. Normally in open positions, bishops are productive the night. So here also black would have a very decent compensation. So we analyze other type of sacrifices. But in the end, we're going to explain in using the most important principle, which is the principle of activity. And I would also like to mention that some of the sacrifices, such as the exchange sacrifice, can also be played in the male game or in the ending. So these ideas can be used on other stages of the game. 41. Activity - Breaking Principles: Hi again, unless now do another practical activity. So the section, as we know, is more advanced. So the positions are going to be a bit harder to evaluate. But in any case, I want to understand the main ideas behind this moves. Let's start with the first position. Here it is black to play, and here in this position, gasoline would be a very natural move. Black has already tonight's developed. White only develop the queen on C2. But why will try to, later on develop the pieces and tried to get these to be shops to become active and tried to claim an advantage. But in this procedure, which has been blade in a few games, Black also tried to move E5. So I would like to ask you, what are the main ideas behind the move E5? In the second position, it is Y2 play, and here it will be perfectly fine to develop the PE shops, for example, the visual 1F1 or to develop the night and hear black men try to play them move night G2, FCX and after, let's say y dx like would take. And here we get a perfectly normal position. But a move that has been tried in this position is M overnight to G5. So the knight is moving again. And as we discuss, moving a piece or upon more than once normally has to be justified. So I would like to ask you, what is the main idea of this movie? If black plays the move H6, and in the last position here, it is black to play. And I would like to ask you, what do you think about casting short here? 42. Solution - Breaking Principles: So in the first position playing the move E5 is a very sharp move. So if we're playing this position, I would not pay these move unless you are very well prepared because here lie has to calculate lots of lines. But the movie is very interesting because it puts pressure on the sender and also it plans to develop the bishop Pilbara square before playing the movie Y5. Here the job is very passive. It might go to the seven bodies not improving its position a lot. That's why the movie E5 opens these diagonal for the bishop and improves its activity. And the bazillion is still quite complicated. But for example, here, if white plays night where three here we will develop the bishop Durbar Square and we blend to adapt the Queen. So we wanted to take advantage of this placement of the queen on C2. So here, for example, if y takes on a five, here, we can just play nitrogen three and attack the queen under 2k. So here plywood gay material. Instead here white mitochondria developing and we get are quite complicated position. We see a lot of tension in the center. As I said, this was Jenny's quite concrete because here, white can also dry today, can D5 and after Daguerre and d5, develop the bishop and attack the queen. And we see that the Queen has to defend the night. But here, black would have the Quinto A5 given a check. And first of all, if we jump to the dual, then here lie would just exchange everything. And when upon, after digging on the form, and if white dries before, black has them overnight takes before, because if y dx then you would just take the rook. And here y can do I actually take this night, but black would win the rook after giving a check. In the second positions. Similarly, nitrogen D5 is quite an aggressive move. White is trying to avoid exchanges and trying to ID spawn an F7. And here I'm telling it the best reaction would be to continue developing. Then later on, after playing E6, undeserved, 36, tried to play them all H6 to kick away these night. In that case, black would be doing fine. But this model also has some practical value because here, after the movie H6, which is stamped into attack denied and then develop here, white has the movement IPV6, which is quite interesting because first of all, black cannot take the night because here we get this very nice checkmate. We again see how moving upon the F bone can be quite risky for the king. So here we have a checkmate, and here y, these are Dunkin McQueen. If black moves the queen Twenty-five, then we would adapt it or black and move the queen to be six straight away, which is the other available square C7 is being controlled by tonight. And here y can dig if black ones to Castle, black cannot deal with the king, like would have today with the night and hear what it has are preferable position because why do we develop quickly and distributions? They will become active very soon. So all in all, I would prefer plain as wide here. So remember one hour upon and place these moves that break principles. We need to ask ourselves if they have any particular purpose, because I'm dance nice moves can be quite dangerous. And in the last position we have a very complicated position here. I'm Cassin, would be just extremely risky because we see that white has four PCs directly or indirectly login at Black skiing. So here in fact, white can continue with the more Bishop takes H6. And after Dagan and Dagan, white jazz gave a piece for two bonds. But why will start at Jack in soon? For example, with nitrogen five H 4s and idea. So this is just very, very risky to play. Does we're here in this position, it is better not to Castle. Again, remember that these are exceptional positions. In most cases, counseling is read, and in fact, these bassoon is so exceptional that here black played the move kinda E7, which looks pretty crazy. But the main idea is to play the movie G5, which is not possible with the king on IE eight. Because here what will take on D5, and we see that this rook would be hanging. But after kindred seven, The Queen is defending the rook. And the move G5 is actually quite a very strong threat because after that, the queen doesn't have many squares. For example, here, if white castles, then after d five, what can sacrifice obese body if white plays him of window h3, which is the other available option after deform, we get this nabla doc and lagoons obese. So here we get this very funny situation on which why these break in principle submit by developing the queen early unblock. He's also doing the same in order to adapt widescreen windbreaks or principle, and so does Black in order to punish white. Here, what could have dried? For example, a mobile ID for trying to stop this idea of G5 and D4. These stopping d4 to not lose a night, but instead hear white dried them overnight, n5, which looks interesting. But after digging or Y5 here, black played him of Quinto A5 at Dunkin, licking and a bond. So here, black one upon under bazillion is still quite a very complicated because y is more developed. These to be shops are actually quite active. So black has an extra bond, but this is anyone's game, and in the end, black still manage to win the game. 43. Outro - Breaking Chess Principles: So I'm very happy that we finalize this section because now we'll learn how to play the game in a much more practical way because our opponent might sometimes not follow the rules or play something a bit different, but we now know what to do. In those cases. We now know one we have to do something specific. One, we don't have to do anything at all. And we also learned very advanced sacrifices that are very hard to evaluate even for the best players. So we are now getting closer to the end of the course. So I'll see you on the next video. 44. Intro - Final Activity: Hi again. So now it's time to do our final practice. And for that, to help you here, I created a checklist for you will see all the most important ideas that we discussed throughout the course in the activity will see real positions, real examples. So don't worry if you find them a bit hard. Because the idea is that you make the effort to try to solve the positions. If you do that, you'll learn a lot from the activity. So let's get started. 45. Final Activity: Okay, so in the first position it is Y to play. And I would like to ask you, how would you pay here as white? So you can take the position and tell me if there's one good move or a void has more than one option, and in that case, you can choose your topmost, let's say your top three or four months. Now here we have a king's bone opening and here blood played the movie night to d4. So these move lives upon on E5 and protected. So I would like to ask you, what would you do here as white are? Let me tell you that the question is a bit tricky. So I'll give you a hint. If white takes only five, does Black have an active reply? You can ask yourself, and you can check other options besides taking only five. Here we have another position. It is black to play and black is upon up. And black here has the chance to take another porn. They take it on S3. So I would like to ask you, what do you think of the move D takes SHA-3 and let me give you another hint, please think in terms of development. In the next position, it is Y to play an White has lots of possible moves here. But I would like to ask you, what do you think about the movie? Night takes F6. And here we're checking their position on black site. So I just took the bond on the five. So the logical reaction would be to take the Pawn back. So I would like to ask you, how would you normally take the spot back? And this is the last position it is Y to play. So I would like to ask you, where would you gasoline here? So normally cancelling here makes sense because we have the gain in the center of this rook might indirectly by looking at the king. So normally he would castle. So where would you cancel here? 46. Activity Solution: So I hope that you manage to understand and solve the positions. If you found them hard. Don't worry, because we're here to learn and put in the effort to solve the positions will already improve your game. So the first question was also a bit tricky because they ask you, what do we play here as white? This is a very well-known theoretical position. It's assisted in the funds. Nicer variation. And here, the most common moves are not really to develop. So white can either develop this bishop or these Bishop. Possibly it would be a bit more logical to develop the bishop on F1 in order to Castle later. So here one move would be the bishop to e2 and then castle. Another possibility is to move the bishop to S4. So we already have two common morphous. And the other common moves are the moves Bishop to y3 and Bishop to G5. So all of the moves, they have subtleties involved, just to mention a few if we develop the bishop to E2. So here normally the bishop is habit more passive than nC four, but on the other hand, it can be attacked easily. So the bishop and C4, although it is more active, it is also IN despondent F7 maybe to attack the king. But here black can attack with mosaic B5, maybe not now, but later on also night to be D7 and nitrified for NIH to be Cx. So both moves are perfectly playable, but they have pros and cons. This is very common unsimilar ideas we can discuss about the book Bishop T2, e3, em Egypt to G5. Also, I want to mention here that this is an extremely theoretical position and pretty much everything has been played here. Moves like Bishop to the 3S1, Queen, F3, even a4 has been played to stop B5 ideas, prophylactic move. And here's what I want to make this very important point that in the open, in some depth, we have many, many good moves. And this is in a way good because it gives flexibility to play. And that's why by applying principles, we can find good most easily in the opening. There's a composition. It's what we call in chess and opening crop. So it's a position in which if we go wrong, we can lose quickly. So before we analyse the idea of taking only five, here, I want to say that if we play our developing move like nitrosyl three or just Gosling, then I don't clearly see the point of this MOOC. Nitrogen for definitely black will not blend to take here because after who take with a queen. So basically blood tests wasted to Tempe to improve the Queen. So this doesn't make any sense at all, is already better here. So cancelling is already quite a good move, untaken only five here. It's dubious at best, prolly bad move because here black has a move window G5, which attacks the night and upon. This is a very complicated position. But the main idea is that if y takes an F7, then black will take upon on G2. And blood will get a much better position even when. So we have to, we move the rook on F1, then here black after taking only four and after Bishop to e2, then night to F3 is a very nice checkmate. And avoid takes the rook than like we'll just take their work here. And after we defend would take another point, we check. And basically these Night is normally going to fall on black has a much better position, much more active position. So this is not good for white. I just want to briefly mention that here taken on F seven is the best chance for white after we take only five. And the idea is to sacrifice the peace after black plays kidney seven to Castle, and then sacrificed the space and try to play against this gain. But in any case, we see that the night take C5 is riskier best. So here we need to take into account practical considerations. First of all, whenever opponent plays a move like night to deform, he's probably burden disposition. So unless we're extremely prepared, taking N5 are ready, can be risky. And also even if taken on five was a good move. Here it is not a good move. We wanted to pay extremely precisely. Whereas if we cancel, then we just continue playing natural moves and get a great position. That's why cosine is a much more practical choice. And we also play against the style of our opponent who wants to attack us. So we'll just play solid moves, so we're playing against our opponent. And this also has a great psychological value because we frustrate our pond. So the third position, it was about taking on S3. And the answer is that taken is not suggested because we facilitate the development of the night. And although black might have playable position, we see that we have all the species waiting to be developed. These bishops trapped there. We analyzed as similar sacrifice on again, White has all of the pieces just very active in the Knights, the bishops. Why discussing soon. So playing these, again, it's extremely risky. So that's why in this position normally blood plays, they move D5. So the five makes a lot of sense because we tried to fight on the center board upon There, were able to develop the bishop. So this is a much more logical move, even though taking on S3 might not be strictly bad. And in the next position I ask you, what do you think about the move? Nine takes F6. So about this exchange. So nominally an item Nabisco burn very close in value. But here we will be changing our best piece, which is the knight on the five For a bishop on F6, which is quite passive because it is blocked by its own ponds. We also need to think about developing the other pieces because white still probably has castle. So moving the bishop would make sense. And also here, the Snider and a3 is quite badly placed because basically is controlled by these bonds. So that's why normally here, what would they move? Like c3 to activate the night, to bring it closer to the center. And also these more Y4 might become an idea to activate the rook. Taken on F6 additionally improves the position of the point. So that's also very bad because we just gave our best pays for about based and improve the position of blacks. Quinn. So in this position, it is blood to play and we have to take on the five because white just took upon. So first of all, we cannot take with the quinn Because the night would take the Quinn. So here, take it on the five. It is possible. But I would say that taking with appointees have been more accurate because if we take with the night, then y gets this two points on the center and will normally play E4. Maybe not now but later. So first of all, here we need to do something about this bishop which is attacked. But we'll gain a central domination after playing E4. That's why if we take upon, then we make it harder for y to play the movie for. And also we already activate these Bishop. And this is another important detail because these measure with a pondering seeks, it was blocked by SON ponds. So now we improve the activity of the bishop. So although both moves taken on the five, with the night over the corner playable, it is more accurate today with upon r In the last position. We have a similar upon structure to the previous one if black 2C with upon. So here we can GAS alone or we can guess it short. So both moves can be played here because after gasoline known, the king doesn't look very bad there when IDS to launch an attack. And this is more of a middle game discussion, but black is very well-placed because blood will basically attacked first. So for instance, if black plays a move C6, and then after a3, a5, G4, them black and played B5. And we see that before. It's already come in with timber organs the night. And also that blood is very well defended here with the night on a fade. Tonight might look passive. Their buddies defendant, quite well, the botnet seven. So this might be playable, but black is very well here. Thus why castle in short is a bit more common than casting long. And after C6. Here, why normally place the move F3 to push E4, which is one of the ideas that I discussed in the previous position. So white has two points in the centre against one pond. So we're trying to take on 126 center is probably a better plan than cancelling long and launching an attack against ticking. 47. Outro - Final Activity: So I hope that this activity was useful for you. And in addition, we learned a few new ideas in this activity. One of them is that in the Urban actually more than one move can be good. So this is very good for us because we can find different ideas will pay in the opening. And also we learn how to play against our opponents, plan, against our opponents idea threads. And this is also great because it has a very strong practical value. So this is more of a middle game thing, but I want to share with you on this course are ready to get started. So now it's time to move on to next steps. 48. Next Steps: Well, lamb were made it till the end. So I still want to give you some small gifts. So first, remember that you have a checklist that you can definitely use for your next games. Secondly, I bought a list of games of the most hyperbola opens that we discussed. Games in which white wins or black wins. So you can study these games to get more familiar with the openings. Unless I decided to play some games may lead to have some fun. But tried to show the ideas that we learned in this course. And also to try to give some more unstructured learning. So I hope that you enjoyed this last video on which I play a few games casually and discuss trying to apply the principles that we learned now about your future improvement, if you already feel more confident when openings, I suggest that you study other stages of the game if you feel less confident there. So that's it for now. I hope that you enjoyed the course and I hope to see you soon. 49. Uncut - Playing Some Games: Okay, so let's play a few games. So the first I want to ask you a few nodes. The first node is that you might hear some background noise. So I live in a city. So sorry about that is if it's a bit annoying. And then I'm going to play a 10-minute game. So hopefully we'll have enough time to explain what I do, do in the game. And during the Games you hear sound every time I'm always played. So hopefully it does not annoying. So let's get started. So I'm 100 and then some planar terminate game with no incremental. And here I'm black. So white basic movie for so let's try playing as a sealant defense, which alike, which is an aggressive option. Number three is logical to play D4. Let's play the move. While this dx is very common here, nice. Let's pay 96 to develop a night. Again, the center HIPAA C4, which is not very typical Because now I might try to get the square root. So I'm going to play G6 later on, bishop G7 and put some pressure here. Well, so here he plays B3. Lets go visit B7. Now we are ready. Wonder, dig there. So that's why he plays I to C3. Ok, let's continue developing our now I also have a trick which I plan to take here. And if it takes, then I will get the rook. Okay, so he plays e5. This is very aggressive. So here I would have to basically calculate what happens if I play the move nitrogen for did you, for attacking this pond and have three Bs is attacking the bonding looks good. So let's try it. Instead of e5, it was probably better to place after like visual b2. Okay. I guess we just do a might have against night xy for so 95. Okay, now this I think is not very good, you know, moving a piece twice. So let's just get the Pantone five. And our IRA plan to take the night and then take the rook. That's why he takes, let's say with the nitric and deal with the bishop of the night. It's pretty well actually. Maybe I'll check with division. I already attacked the rook. And this node here is centralized, but it is not stable. And as we discussed, because I can kick it away these easily with E6. So while while this just this just done this iraq, so. I don't see anything here, so let's just take the rook. And this is already a huge material advantage here, cathode here, District of play night F6 because I cannot take upon, but again, just take with the bishop. So okay, so black resigned. So we can see that basically white, you know, broke a lot of opening principles. And that's why he got this disposition C4. Maybe it's not about, not very common, but why give this square term easily? But the moves that I would criticize, okay, already, B3, Oberlin diagonal, the diagonals might be a bit risky, but while hearing five, definitely not advised. And here while 94, array attacking opponent moving a piece, a piecewise already, pretty bad. Okay, and then here we need to just blunders. The rook. Ruby one here was necessary. Lag is already much better because I'm upon up. I have better development to I have everything. So let's play another game. Okay. I'm going to click on new opponent and other terminate game. So let's try it with, let's write a movie for he pays E6. We analyze this fs, which is called the French defense, is actually quite interesting. At least Dewey's quite annoying to play against it sometimes because it's very solid. I I normally had to attack, so okay. He pacified, which is not the most common reply. D5 is more common. And if I play night, we have three here transpose into a zillion defense. So because I play E4 and he plays it S5. So we takes and now he plays nitrous E6, perfectly logical. So now I can play Electro C3 to develop. He takes, which I think is not very good because exchanging, we should do it whenever we get something in return. But here we just exchange the nights and I improved my queen. So are like digging into four. And I get this screen here, which if you're an idol C6, the queen here would not be well placed, but now he doesn't have night so that there is very well placed on here. Okay? I can move the bishop on gasoline short here or here. But I could also try to Castle alum. So let's try to be aggressive and gasoline. I already have, I think a slightly better position because a more developed so that each of us to go here. If I played to afford, then he might have E5 ideas attacking the visual and the queen. Okay, so let's comes along. Let's go for it. Here I might already think about aggressive moves at night to b5. You know, looking at this pawn, anybody respond, not wasting time to get the a point? Nothing is really a good idea. Maybe the D6 spawn. But after 95 he played, he might play maybe D5. So you know, when in doubt, I would just develop and place our vehicles. So here I can play. I gotta develop the bishop from F1. I can develop somewhere. But here, but here if he castles GD, We have what we call opposite side Kosslyn and we'll try to attack each other and push bonds. So if I put the bishop and S4, for example, he Maya jacket later would A6 and B5. I would say it's about moon, but maybe here what I can do, I can try to, to start these attack with bonds. Maybe with the move F, F3, and G4. That's an idea. So the bishop is already at least somewhat active here. So now I can try pushing the ponds. That's right. I'm not sure if it's a good idea, but this right. So he cancelled short. So then this was my idea to start pushing ponds and go for the kill. Will he plays D5 is a very concrete move. So the principle is that when you play on the, on the side of the border not listed on the Qing side. He tries on the center. But here I think I can well, I guess that I can take this bone because I have more pieces. I have 1234 pieces looking at the bone. And he has 123. So normally you can take the Upon. This will open the position. And nowadays to play G5. But he will have, he will move the night. And this point will be Attack on G5 with the bishop and the Quinn. Another guess, eBay, E5. But I think that that's not very dangerous. We will have a strong center. So I think I might take the BON. So let's try it. So it takes about with the bone. So now let's try taking the five, which was my idea. Because if I exchange quizzes and wanna be upon up. So without quiz, this position may become tricky because lines will open here against my skin. But I'll try to exchange with nausea, fall, make it but I'll dry. So now I have now I can take here or here. But actually I'm not foster take this night is strong there, so normally he will he will take it sooner or later. He has more time. So I have to be a bit careful. He has nine minutes and a 5.5 minutes. So I take an logically Now, he wouldn't like to exchange Queens. So this is more of a middle game engine concept. When you are materially down, normally is not a good idea to exchange business, but we'll see what he does. So now this point here doesn't make a lot of sense is if I am not going for an attack, paying these moves before doesn't make too much sense, but obligee foreign than HIPAA D5. So but now if I could go back, probably would go back with this bond. But that's not legal. And just yet, so that's perfectly logical to play. Quincy seven on the position now gets quite tricky. So he's upon down, but he, he will develop these Bishop who tempo attacking the Queen. So what I can do here, normally you want to attack Ladino. Position is not ideal drug, then you have to play more solid. So here I'm going to try again to exchange with Quincy for to see what he does when he should know my not exchange because this will improve. The bishop. I expect the more liquid wave five, keeping the Queen's trying to make it hard. Yes, that's a good move. I also wanted to make it a bit hard for him. So how about I try to move gathered about the moon Bishop to D2, but he will play when B6. And now he plus WHO B6 and attack me. So this position is getting quite tricky. And if at Beirut D5, this quite important, if Iraq D5, tagging the queen. Here, we have an average BNO in check there. So how about if I break when D5, then he might go back with Quincy seven. So now I have to play a bit faster because I only have four minutes. Oh, model. That basically blandness of Queen position was very tricky. Because after Queen to C7, maybe I can repeat with Quincy do with before. Because I think that he he had very good conversation. There is just a middle game compensation in the form of attacking basically. Well again, weaker development, you know, attacking more quickly. But now we just landed a queen here. So I'm going to just take it. This normally should be enough to win the game and extra more than enough. So okay, he continues playing. But then I can just say anything here. I just need to be careful not to do blender queen. But now this I want to play with up to D4. Jack made him yeah, that was my idea. Now, but he has 600 is not a good move. And now basically I will exchange everything. Exchange Brooks, I get an extra, normally quite easy to convert. List these as exchange everything. So here I have a nice trick. I can take an S5 because there's a checkmate. If he takes it when we can blade. It is called the back rung checkmate because his background, what he says is we call it this week. This normally happens in the middle game because whenever we have less pieces on the board, they gain has picked some, some air. We call it to take some loft, which is a German word. So basically here I can play this. This is not a sacrifice because I give checkmate. So after this, I give jQuery. Okay, so let's play one more. But before that, I want to say that the position was quite interesting. So here we got a Sicilian by transposition. If he plays B, D5 is a French, but if it is a silicon. And this is pretty much illogical, we develop. So he had vertebrae aggressive. These modifiers actually was quite interesting. And here even though I gained upon, he will get quick development because visual B6 comes with Dembo. And here basically have to quantify here to play Quincy seven. I'm probably IE I would have repeated movies. I'm still not sure but because he was borrowed times L. Okay. Let's play one game. Case. He plays E5. Now let's try something different. Let's go for if I've last game we played insisted and defence. Okay, Bishop C4, not the most common move. Perfectly playable. Here is a night we have first is more common. So let's play nitrile F6. We attacked upon. Actually these movies, quite tricky. And I'm not saying it's an interesting move. So here we can develop the bishop C5. That's one idea to play, C6 and D5, which is a bit complicated, is ambitious for black, but is a bit complicated. I'm not sure if my opponent is repaired on this line. So in this case I just develop. So notice you six, like I can develop Eigen castle. Maybe, but maybe I would pay H6. Particularly hearing if he pays a move like A3. It has a purpose. He wants to be bishop to a2, Maybe if I attack the bishop. But since he plays a slow move, I can also possibly play a slow move. So I'm going to play H6 to prevent the bishop to G5. Because after Bishop to D5 him, I have ideas like night to D5 pinning this night. I cannot take, because he would take the queen. Does y here? I can play H6. Okay, this is logical. Here. There's an idea to play under G4, which is aggressive because I look at this bone but he will castle on the exchanges normally or not. They are complicated but they are not normally favorable for me in this case, given to wider pieces, four upon anaerobe. So castle. And now I normally continue with this segues and develop the bishop. Here are two E6. Yeah, I was, I was actually going to say that, that he might play these idea to get these Bishop because this bishop normally is strong hearing although in, at this point. But on the other hand, to get this visual for you will waste some time be right, because he basically, if I draw a four here, I can go back to B6 or I can leave it there as usual pros and cons. So here probably I'll leave it there. So no way to know to improve my development. So we have to be six, I continue developing. And if you takes, then I'm going to play, well now the n Our take, and now I get more, more space for the queen. I also have this nice controlling the center because D4 for him now is pretty much impossible. Again, he pays h3, which is interesting. I am not sure if he wants to play G4 after visit to H5. So he might have this idea, I'm not sure if it's good or not bad. So the posterior is, this one is also complicated. But it makes more sense. I don't wanna give the bishops. He will get two bishops. So let's go for it. Okay, G4. There's an idea sometimes to sacrifice the piece here. And if it takes, then, then I have this pin against the queen. What actually hear? Well, and then he will pay C3 to stop 94. Because if I pin the Queen and 94 is very strong. And actually, I'm not sure what goes on there. Because if I take on G4, he takes a day with the bishop. Yet then he will pay C3 to stop night before Quinn F6 and then he will taking Kenji do. And then I write req when G6. Not true. Well, what goes on there? Maybe have conversation, but again, if it's very unclear place of him, something you know, more natural. So here, although after we jump to D6 here, my bishop, for now, it is dropped for now. But on the other hand, he developed Qi He weekend. He's getting a little bit, so it's WIG and he plays night, which for he wants to take here now. And I cannot take with a point because making basically I cannot take because it's an illegal move because the King will be, will be taken. So I have to do something about it. So I can either move the bishop, which might be interesting, or I can move the decane. I'm gonna move the bishop because I have a trick now, which is to take somewhere today Connie for, for example. And then take this night. You, if you'll fall for it. But Madrid yet nitrate five is a good move. And the position is getting pretty wild, is very aggressive. I gave a given credit for that. So I'm going to play. Night before. Okay. And now I'm getting a loan term, so I'm going to have to play faster. So I don't want to take this night for now because P probability with the bone and have a nice base advantage. We still haven't finished development, at least not entirely. But now I'm going to have to think where my queen is going. Ideally, I would like to have some attack against this ponds string Latino clearly, but I'm, I think of that idea. I have an idea or to transfer the night before because now he has weakened. This is square a little bit, so yeah, let's bring this night. If it takes, then I'll take night. Although he might have an idea now, thought about taking an Quinta B3. Ahima Blake when B3. Now that might be interested in, actually, that's a very strong move. They are going to be three. Attacking here on here. Might have in an interesting idea. Now he plays a four. Again, very aggressive, so we know he's dial. So probably here I'm going to exchange Okay. Maybe I'm going to take first on a five-year yet. Because now I see that if start exchanging So first denied they're gonna for anomaly, he'll have to give up this bishop. And then he will have some, you know, some holes on the black squares. How this does, does my idea. So normally I expect him to take the bishop. He might think of this intermediate move, take only five. But I'm, I have also some intermediate mosaic dignity for now, so okay. So he takes their nowaday with the night, make sense. He will normally take with the bishop. Although since he plays very aggressively, he might think of taking on the rock and then the bishop so extended the sacrifice. So given a sacrifice in an exchange. But that's not the case. But in this case, he gets some weak squares. So hopefully this is good for me. Now, windy six attacks the rook. I also have some crazy moves and thought about. But it doesn't work. I want to give a check. This night was right here. I have some ideas like even a check on G5 and attacking again. Okay, let's play quitter D6, attacking rook. He doesn't have robbed before because in i takes. And here we continue with normally ROCC ideate and try to put some pressure on the central ponds. He pays. Okay, so thinking about night H5, because you cannot take, because I did with the Queen. But you can just move the MOOC. So also I can improve my night. Sorry, I'm a little bit. So he has a very strong bishop looking at this one. I hope to improve my night sooner or later night to D7 and 95. So we'll see what he does. Position is complicated. Definitely. Catch it up a little bit on time because he has almost three more minutes. So ideally, thinking now. So the logical reply as logical continuation would have been to bring, you know, the last remaining piece, Rudolf one. At least I think that was a very interesting move for him. Now queen to E3, E5. But I can stop it normally with this move. Although he might have F6, which is very sharp. Okay, let's play this move first. I'm always thinking of ideas like night H5, but this move has to be good. And remember, if we put an item on a corner, then this visual that is a good move, otherwise, we just worsen the position of the night, the placement. So ideally denied. If it's stable here, it would be very happy. Just attack in the bishop. Controlling, you know, very important squares. Even looking at the King after night, we have three. So. If I convey that move, I would be happy. But on the other hand, you know, it would take them so to Tempe nitrogen T7, T5. So I want to do it whenever. I'm sure that's good. So he goes again, very sharp. This is probably not very good. Because this idea is not, not very serious in my opinion, but in my Vc. Here am I even try to bring it to D5 to begin that I do. But okay, let's write this right here. In any case now he definitely doesn't have this more because I will take even with the Queen. Now the queen may also come to F6 and the nitrogen five. So that will be my, my dream scenario. But of course it will try to make it harder for me. Now I have one minute. So I'm going to play definitely faster. Soloist. Played is move, which we said that it was, it was good normally. So okay, now here's rule d one. So this is getting trick, definitely untaken or G6 later. So, so I might have to try it to Blake in F8. If today's rook d1, I'm going to play quickly, came to F8 because he has ideas of taking or H6. And this point would be, and now we get into what we call a time travel. We're getting closer to that. So this is the point where we start to make it lots of mistakes normally. So hopefully I won't make too many. We always make mistakes. But yeah, that's a good move. Let's go here and hope for the best. So now I have my own ideas no, taken there. Wow. Was that okay. Definitely. Taken there. If I take i don't see actually any moves for him, so I will take the so basically exemplifies the R2P. But I don't believe in that. He doesn't even have looked to for so so I go here. You know, my king normally will be safe on E7. Normally. I, and I might even think about running to the queen side. Here. I would be very happy, but it's a long row. Denote now have an extra rook. So I also plan to take here for an exchange queens. Okay? Okay, so here now I can just take this bond. He doesn't even have a check. Okay. Now I have to hurry up one-minute anomaly if he doesn't exchange quiz now have Queen, F1, break Delbrook. So this should normally be over. Hopefully. Also have Quinn F3 if it hasn't exchange with so yeah, that's exchange means let's be safe now because I'm low on time. Now I hit OK. Now I'm going to try to give him checkmate here. I have this. And this is Jack made. No joy if you will fall for it, but we might write F6 to Jack made me, but normally check me first to F6 planning rook, age eight. Okay, now, okay, so he wants to be F6, just segmented. So check me on the next move. For him. I only take this bond we checked two avoided anomaly. H2 will be generated. Okay, so he resigned. So this was basically a very, very complicated game. So if I go to the critical position, he might even be better writers, better, slightly better. So here I actually missed, you know, a plane on, on a quick time control. We b3 here was very interesting. Probably a, I would have to give a upon four. I didn't like it because it looks aggressive, but at least it makes life easier for me. And now I have this continent lay on the, on the dark squares. Here. Yeah, here, here, rook, if one was quite industry to activate. These are also called the principle of the least active fees to activate. The last piece, you know, all of his business here are fairly active, so just bring the last the last guy. Ian here. Yeah, here. He just basically panicked. So here the position is is pretty wild, but probably here he didn't want to defend because in the end, now I'm trying to get some countably here. So he didn't want to defend with most like the group to G3. So if he doesn't have an addDoc here, probably I'm I'm doing very well. But otherwise, so if I'm not getting checkmated, then am I continue. This rock sacrifice was not was not good. Just one check and then I go back here and does it. He doesn't he cannot take here, so okay. So hope I hope that you enjoyed this. Does games. So I'd at least I tried to put into practice what we learned in the course. I chose Add, didn't tell me. I thought it was enough to explain and play at the same time. Not sure if I was too quickly or not, but I hope that you enjoyed it.
