{ Hi all! Welcome to a new studio. In this study I am going to tell you about King's Indian Defense.

King's Indian Defense is one of the most popular and AGGRESSIVE ways to deal with the opening move 1.d4. It is a semi-closed opening. Black gives up the center and hopes to keep it stable while attacking the opposing king. This defense was used by great players, among them, former world champion Garry Kasparov.

Before we begin, I would like to comment on something.
In the comments of my previous studies I have seen that many have corrected me in some words, and that is really my first language IS NOT ENGLISH. So sorry if I don't say a sentence correctly.

Support my study: https://lichess.org/study/4JQtS6iu

With nothing more to say, let this wonderful study begin!
Press the space button to start :) } 1. d4 { Play 1.Nf6 [%csl Gf6][%cal Gg8f6] } 1... Nf6 { You can start differently, but the correct one is Nf6. } 2. c4 { Now play 2.g6 [%csl Gg6][%cal Gg7g6] } 2... g6 { This move is that of the King's Indian Defense.
The idea of this move is to take the bishop to g7, where it will be very well placed. [%cal Gf8g7] } 3. Nc3 { So where should this bishop go? [%csl Gf8] } 3... Bg7 { That's! } 4. e4 { Normally when the white player makes e4 we respond with d6 (You can do it now) [%csl Gd6][%cal Gd7d6] } 4... d6 5. Nf3 { What should you do now? } 5... O-O { Very well! This is the King's Indian Defense.
You develop the pieces of the kingside, so that it castles as soon as possible. In that course, the center is a bit weakened, but then we will fight for it with c5 or e5. } *

{ Hello everyone! This study is about the Slav Defense. The Slav is a classical response to 1. d4 and gives black solid fighting chances. If you don't like wild crazy games, but like a solid structure and position, this is the opening for you. Let's get started!

Our opponent starts with one of the best moves, d4. } 1. d4 { In the Slav, we respond classically with d5. We are not trying to provoke a fight with the King's Indian or playing with fire with the Grunfeld. We are following classical chess opening principles.

We don't want to take the pawn right now giving up central control. Let's play c6 defending our pawn.
Right here, 2. ...e6! is also a great option, but normally that leads to a passive light-squared bishop, or the French-bishop, stuck behind the pawns of its own color. We want it to roam free!

Then you can castle short. The main pawn breaks in the position are e5 and c5, make sure to keep those in mind and see when you can play them to break down white's center control. This will be a good game for you!

{ Hi all! Welcome to my new studio. This time we are going to talk about the Queen's Gambit.

The Queen's Gambit is one of the most studied openings, and one of the most popular in chess, so much so that it has a very famous chess "miniseries" with its name.
This opening is VERY USED by the great chess players, and you should also use it if you want to win many games.
But first, you must learn it, and that is why today I will teach you to play "The Queen's Gambit."

Support my study: https://lichess.org/study/4JQtS6iu

Start the game with 1.d4 [%csl Gd4][%cal Gd2d4] } 1. d4 { The 1.d4 move leads to slower and more positional play. } 1... d5 { Play 2.c4, the move that distinguishes the Queen's Gambit from other openings. [%csl Gc4][%cal Gc2c4] } 2. c4 { This is the Queen's Gambit.
Remember that in chess a gambit is the offering of material in exchange for an advantage in the development of the game. In this case, we offer a pawn, and in return, we have better control of the IMPORTANT central squares.
As I said earlier, the Queen's Gambit is one of the MOST STUDIED chess openings, so there are MANY variants. But don't worry, in this study I will show you ALL these variants in an easy and fun way :D } *

{ This is the main scheme number 1 that I will teach you. I do this so that instead of memorizing, you understand the Queen's Gambit.
When black accepts our gambit, we usually want to get to this formation of pieces.

The king will feel good about kingside castling, once the bishop captures the pawn on c4 after accepting our gambit, and the knight goes to f3, his standard square.
The queen and rook will feel VERY GOOD on the open c-file, the knight will go to its usual c3 square, and the dark-squared bishop (although it is locked in) can go to d2. } *

{ The second scheme represents the Declined Queen's Gambit. Normally we want to have the pieces in these squares when Black does not accept our gambit.

It hasn't changed much to the scheme number 1 that I showed you, only now the light-squared bishop will go to d3, and the dark-squared bishop is not locked.

Keep these squares in mind for your pieces in your games with the Queen's Gambit. } *

Do you remember the first movements? } 1. d4 { Very well! } 1... d5 { And now? } 2. c4 { Excellent! } 2... dxc4 { Black will NOT ALWAYS accept your gambit, but be prepared if he does. The best move we have when black accepts our gambit is 3.e3 (you can do it now) [%csl Ge3][%cal Ge2e3] } 3. e3 { With this move we open the way to our light squared bishop, who will normally regain the pawn that you lost. [%cal Rf1c4] } 3... b5 { With 3.b5 Black surely thinks he is defending the pawn, but this move is not good at all.
Play 4.a4 [%csl Ga4][%cal Ga2a4] } 4. a4 { Here Black can capture or advance, in any case it will be very easy for us to capture those pawns. } 4... c6 { Now Black thinks he is defending the pawn, but again, this move is a mistake.
Capture the pawn } 5. axb5 cxb5 { This is really the mistake.
Now the diagonal h1-a8 that I indicated with the arrow is much clearer than before, and this hurts Black.
Can you find the move that gains material for the white? [%cal Gh1a8] } 6. Qf3 { That's! [%cal Gf3a8] } 6... Nc6 { Interposing the knight is the best option for black. } 7. Qxc6+ { Double Attack [%cal Rc6e8,Rc6a8] } 7... Bd7 { Take your queen to a6 [%csl Ga6][%cal Gc6a6] } 8. Qa6 { Now you have advantage material.
This is how black should NOT play, if your opponent plays this way, you can take advantage of the mistake and win the knight! } *

It is even more solid than the Slav, as it has a more solid pawn structure. The problem is that the light-squared bishop is now locked in with his own pawns. [%csl Rc8,Yf7,Ye6,Yd5,Yc6,Yb7][%cal Yb7c6,Yc6d5,Yf7e6,Ye6d5] } 5. Bd3 ( 5. Nc3 { This is good move, but not is the best now :( } ) 5... Nbd7 { What would you play in this position?
(Pssst, your king is in the center) } 6. O-O Bd6 { When your opponent plays the Semi-Slav, it is best to move this knight to d2 (you can do it now) [%csl Gd2][%cal Gb1d2] } 7. Nbd2 O-O { The dark-squared bishop feels sad :,(
"A good idea to improve a piece is to try looking for pawn breaks."

{ This is the final part of the study, thanks again for being here.

What is our first move? } 1. d4 { Very well! This play leads to quiet (usually) strategic positions, a slow game of many maneuvers. } 1... d5 { What should your second move be? } 2. c4 { That's! You offer a gambit in exchange for control of the central squares.
Now black can choose to accept or reject the gambit, either by playing one variation or another.
The Queen's Gambit is one of the most studied and popular openings in chess.
Now put what you have learned into practice! Thank you very much for viewing this study, I am Lenin Perez and see you in a next study! } *

{ This is a study I've made for my own personal London System repertoire. It's a system that can be played against almost anything black dreams up. It can be used as an opening to build up a small positional edge or as a crazy attacking opening.

Many of the games and commentary given were found in: https://lichess.org/study/GNlZ2WKx . If you want to play the London make sure to check it out: It's a really great study with lots of high-level example London games. Another study I found with interesting ideas in the London you may want to look it is this one: https://lichess.org/study/KjivNw7F.

Green - typical positional moves
Red - typical attacking moves
Blue - typical pawn breaks (usually against a black c4 advance) [%csl Ge5,Rh7,Rf7,Gg3][%cal Ge1g1,Ge1c1,Gf3e5,Gd2f3,Rd3h7,Rf3g5,Bb2b3,Be3e4,Rc2h7,Rg5f7,Rg5h7,Gf4g3,Gc2b3,Rg2g4,Rh2h4] } *
