1. d4 { If you play 1. d4 as white, you should certainly have a good option against the King's Indian. I'm recommending the Sokolov Variation.

{ Hi! You've probably heard about an opening for white called the London System. In this study, I will teach you the basics of this popular opening.

If you enjoy this study please click the heart button
(under the h1 square). Thanks!

Degocortes. } 1. d4 { We will be starting with d4. It is not as aggressive as e4 can be but d4 is a good middleground between aggressive and solid games.
To start off as an example I will show you the ideas where black plays 1...d5. 1...Nf6 is a popular choice as well. [%cal Bd7d5,Bg8f6] } 1... d5 2. Bf4 { This is the trademark move of the London Opening, where you play d4 and Bf4. The idea is to build a solid pyramid in the center with e3 and c3, and the bishop on f4 will be very well placed.
This is as far as I will go for this chapter. In the next few chapters I will go into more detail on the ideas.
PLEASE DON'T STOP HERE. Continue through the next 14 chapters (in the top left corner) [%csl Ge3,Gc3,Bf4][%cal Ge2e3,Gc2c3] } *

{ Hi, welcome to my new study. Today, I have created a repertoire of openings for those players who start their games with 1.d4, which are positional, solid and calm.

Before starting, I would like to give some information:

IMPORTANT: From today, I will start creating 2 studies per week, probably on Mondays and weekends :)

If you are a faithful follower of 1.d4, you must know this good repertoire of openings, so press the following chapters and I will do the rest :D } *

[Variant "Standard"]

{ Well, before I start to see the opening variations with 1.d4, I ask you again to like this study, please, since I try very hard to create it, but after a good effort comes a great achievement and way, no?

Well well, let's get started. Play the move we're going to focus on today, 1.d4! [%cal Gd2d4] } 1. d4 { As I said, we will talk about this initial move, which is much more careful, cautious, and positional than the others, like 1.e4 for example. } 1... d5 { When you don't know what to do, simply follow the moves that I indicate with the arrows. [%cal Gc2c4] } 2. c4 { This is the first opening, or variation that we will see, that is, the Queen's Gambit. The newest ones will know this thanks to... well, I don't know... do you know? Be that as it may, the Queen's Gambit is a wonderful opening, and one of the most common and standard openings in chess. Some time ago I created a very complete study on this, you can see it here: https://lichess.org/study/JkPnQ5g5
Speaking more of what is happening on the board, now you give up one of your pawns in exchange for other advantages that are not determined by the material. } 2... dxc4 { Now, by capturing that gambit, Black loses control of the center, since one of his pawns is not fighting for the center.
Play 3.e3 [%cal Rd5c4] } 3. e3 Nf6 { What I think is great about the queen gambit, is that apart from gaining advantages other than material, you can also get that pawn back quickly!
Come on, what are you waiting for, do it! :) } 4. Bxc4 e6 { Develop your knight } 5. Nf3 { Very well! This is a very common way to play the Queen's Gambit when the player with the black pieces accepts the gambit, now he may be thinking of playing c5 to damage your powerful pawn structure, and fight for the center, something that you perfectly mastered since the beginning :D [%cal Yc7c5] } *

You play 3.Nc3 } 3. Nc3 Nf6 { What is the best square for your c1 bishop? [%csl Gc1] } 4. Bg5 { The black knight cannot move! For this reason, your opponent's next move will be 4.Be7 [%csl Rf6][%cal Rg5d8] } 4... Be7 { Develop your knight [%csl Gg1] } 5.

In this study, I explain the London System in a simple way: https://lichess.org/study/p1pdMu9b

Now, your pawns are like a stone! Light squares are weak, but that's what your mighty d3 bishop is for.
In my openings section in my studies, I did a study for this attack and it has more than 1,000 likes. You can watch it if you want to learn this great attack!: https://lichess.org/study/9uKfnEnT [%csl Gd3,Yc3,Yd4,Ye3,Yf4][%cal Yc3d4,Yd4e3,Ye3f4] } *

{ You know what to do } 1. d4 d5 { [%cal Ge2e4] } 2. e4 { Here White hands over the 'e' pawn and intends to continue with Nc3 and f2-f3, usually on the fourth move. White gets a tempo and a semi-open f-file in exchange for a pawn and White aims for rapid development to attack in the future. } 2... dxe4 { Develop your knight [%csl Gb1] } 3. Nc3 Nf6 { Now, 4.f3! [%cal Gf2f3] } 4. f3 exf3 { Capture the pawn } 5. Nxf3 { The Blackmar Gambit is (like all gambits) a way to gain other advantages outside of the material (such as the development and activity of pieces) to attack in the future, although this is still a gambit of minority use and according to the most chess theorists doubtful; that is why its use is restricted to blitz games. } *

As you know, White will start with 1.d4. Now you must respond with 1.d5 [%cal Gd7d5] } 1... d5 2. c4 { This as you know, is the Queen's Gambit.

Nf3 { Now, play 4.c6 [%cal Gc7c6] } 4... c6 { What characterizes the Semi-Slav defense 4 .... c6 is the move c6. If done on move 2 the variant is called Slav Defense, and if done later it is called Semi-Slav.
The Semi-Slav defense is more solid than the Slav Defense and because of the formation that your pawns adopt, it means that White has no attack options, but the downside is that your bishop on c8 is locked in. } *

But, what I am telling you now to add more things to your repertoire is 3.g6 [%cal Gg7g6,Re7e6] } 3... g6 { The Grünfeld Defense is a popular and effective chess defense against 1.d4. A lot has been played, even at the world champions. The Grunfeld defense having so much versatility in the game has been highly appreciated by Grandmasters. Both Pachman, Botvinnik and Alekhine played it and today give names to many variants, this is why this Defense is so popular and is always an option to play. } 4. cxd5 { Capture the pawn [%cal Gf6d5] } 4...

To play the Benoni Defense, you must play c5 [%cal Gc7c5] } 2... c5 3. d5 { [%cal Ge7e6] } 3... e6 4. Nc3 { Capture the pawn } 4... exd5 5. cxd5 { How can you support the c5-pawn with another pawn in a firm way? } 5... d6 { The basic idea of the Benoni is to give up the center in exchange for unleashing a strong attack on the queen wing thanks to its majority of pawns in that sector.
Black's main ideas in this defense are: the queen plays a5 to press on the c3 square
black plays an early b5, often and as a main idea in the form of a gambit } *

Now there are many second movements of the target, and I consider this defense rich in theory, so I could not show you ALL the variations that exist now, so if this study is very supported, I promise to do an in-depth study on
this defense.
In general, Black will try to attack the kingside, and White must counterattack in the center. } *

[%cal Gd7d5] } 5... d5 { The Stonewall Defense is the most characteristic of the Dutch Defense, it consists of putting the pawns on c6, d5, e6 and f5, leaving good squares for the knights on e5 for White and e4 for Black. With this structure, the center is static and Black passes the pieces from the queen's wing to the king's, to launch an attack with g5. } 6. e3 { [%cal Gf8d6] } 6... Bd6 { Advantages: Your pawns form a stone wall and are very solid. Your opponent CANNOT attack you. Your kingside develops quickly. You have the important e4 square for your knight.
Disadvantages: Dark squares are not your greatest strength. Your queenside pieces are a problem, especially the c8 bishop.
Still, this is one of the solid defenses in chess. } *

1. d4 { Keep playing 1.Nf6
By the way, when you face 1.d4, what do you usually play? [%cal Gg8f6] } 1... Nf6 2. c4 { [%cal Ge7e6] } 2... e6 3. Nc3 { Now play 3.Bb4! :D [%cal Gf8b4] } 3... Bb4 { The Nimzo-Indian defense is a chess opening and constitutes one of the most popular and effective defenses against the white move 1.d4. Its name comes from the Grand Master Aron Nimzowitsch.
There are a lot of variations, but the strategic ideas are simple. Black will try to launch an attack on the center and on the queen's wing, while White will do it on the king's wing. } 4. e3 { How can you grant security to your king? } 4... O-O 5. Bd3 { [%cal Gd7d5] } 5... d5 6. Nf3 { And 6.c5 :) [%cal Gc7c5] } 6... c5 { In Nimzo-India Black is generally ready to concede the bishop pair after playing ...Bxc3. As a dynamic compensation, they usually double the white pawns on the c-file, which represents a static weakness, and win the game against the central squares d5 and e4. } *

Bb4+ { The Bogo-India, takes its name from Bogoljubov, and is similar to the Nizmo-India, in fact, if White plays 4.Nc3 it is a Nizmo-India. } 4. Bd2 { 4.Bd2 is the most common line; the bishop on b4 is now threatened and Black must decide what to do about it.
Play 4.Qe2 [%cal Gd8e7] } 4... Qe7 { 4... Qe7 This is called the Nimzowitsch variation, defending the bishop and postponing the decision of what to do until later.

{ I thought this was not going to end, but yes, the study is over. My intention is that now you have a wide repertoire based on the move 1.d4, but if you want another type of repertoire you can leave me in the comments.

Also tell me which opening you found interesting for a future study, and don't forget to support me with your positive comment and your like. Always keep an eye out for the two studies per week.

Thank you very much for watching, I'm Lenin Perez and we'll see you in a next study! } *

This study is a top level study for endgames.

The material is organized by type to help you find what you are looking for. It is *not* the order in which you would necessarily want to learn the material. See the next chapter for advice on that.

This study is linked from the studies:

Beginner: Curriculum <--- START HERE: The Endgame
Chapter: The Endgame
https://lichess.org/study/Ztgx3vJq/Vooa3887

Intermediate: Curriculum: Endgame
Chapter: The Endgame
https://lichess.org/study/QjfpcMCD/S61IdQSQ

Endgame practice is here:
https://lichess.org/study/dWUwAWzA

The position is Lolli (1763) as presented in Irving Chernev's book "Practical Chess Endings".

As we will see later, the endgame Queen and King versus advance Bishop-pawn and King is a special case. Black is threatening to get a Queen and draw. What should White do? I'll put the solution here for completeness.
- } 1. Qb3 { Fastest. White wants to do two things 1) stop Black from getting a draw by queening, 2) stop Black from getting a draw by reaching the corner. } ( 1. Qd3+ { Here is a line presented to show what could happen if White is unaware of the danger. } 1... Kc1 2. Kf3 { White hopes to attack the pawn with the King and Queen, thereby winning it. } 2... Kb2 $1 3. Qd2 { Pinning the pawn so it cannot queen. } 3... Kb1 $1 ( 3... Ka1 $2 4. Ke3 Kb2 5. Kd3 Ka1 6. Kxc2 $18 { Winning. } ) 4. Qb4+ Ka1 5. Qc3+ Kb1 6. Qb3+ Ka1 7. Qxc2 { Stalemate! } ) 1... Kd2 2. Qb2 Kd1 { Clearly Black does not want White's Queen to reach c1. } 3. Kf3 $1 { What's this? Allowing Black to queen? } 3... Kd2 { Black sees that queening would allow a mate in one. } ( 3... c1=Q 4. Qe2# ) ( 3... c1=N { Underpromoting does not help Black. } 4. Ke3 { Threatening Qd2#. } 4... Nb3 ( 4... Ke1 5. Qxc1# ) 5. Qc3 $1 Nc1 6. Qd2# ) ( 3... c1=R 4. Qe2# ) 4. Kf2 Kd1 ( 4... Kd3 5. Qb3+ Kd2 6. Qe3+ Kd1 7. Qe1# ) 5. Qd4+ Kc1 6. Qb4 Kd1 7. Qe1# *

{ In Jeremy Silman's book "Silman's Complete Endgame Course: From Beginner to Master", he organizes endgame material by rating. Why? Here is what he says in the book:

"By offering instruction that's tailor-made to fit a player's individual rating group, and is in accord with that player's future goals, I make endgame study easy to grasp and extremely practical for players and coaches. Of course, each coach will have opinions as to what endgames are appropriate for each rating group, so personal adjustments can always be made. Nevertheless, coaches will find my book to be an invaluable teaching tool that they can use with confidence."

Here is a link to a study listing recommendations based on learning order:
https://lichess.org/study/et9oNtIk

What should White play here?
- } 1. Rc3 { With the Queen trapping the King on the edge (the h-file), all that is needed is for the Rook to check safely on the h-file. The h3-square will do. } ( 1. Rc7 $4 { Stalemate. Draw.
White thought that this move would trap the King on the back rank, which it does. Unfortunately, Black has no move now.
How do you avoid making a mistake like this? The common wisdom is that you would look to see what Black is going to play after your move. Indeed, that should be part of your move selection process, as we discussed earlier in the course.
The bottom line is that you have to have board visualization, the ability to see what pieces are attacking what squares, and the ability to do this in an imagined future position. } ) 1... Kh7 2. Rh3# *
