3 + 1 plans

 Long term plans can only be based on moves that are irreversible: Pawn moves Exchanges Castling Promotion Development Pawn plans Pawns can steer the game in 3 directions: LoA battle Mobile pawn roller Endgame In the past, I considered piece activity as the nec plus ultra of positional play. Creating LoAs to increase piece activity, restricting pieces with pawns. The LoA battle has its own scenarios. With a mobile pawn roller, you use the pawns as a battering ram to breach the enemy lines. The pawn structure is related to the endgame. When you think all pieces away, do you have a winning endgame? Exchanges Piece exchanges change the dynamics of the game. They can be used to: Reduce the dynamics of the pieces after a certain advantage has manifested itself Change the balance on a color complex Get rid of a dangerous enemy piece Get rid rid of your own problem piece Change the pawn structure Development Development is about the temporary piece balance. Which attackers are ready to st...

The hart of positional play

Image
  I read many books about positional play. I acquired many dots without being able to connect them. I didn't find books that are helpful. Two weeks ago I had another look at the dots, and finally it started to dawn on me what it is all about. Positional play is about pawns and exchanges. Why? Because pawn moves and exchanges are irreversible. You can only build long term plans around things that are irreversible. Now I'm trying to build a consistent framework from here. It is quite exciting! I even won my first positional game! I didn't know I could do that.

Starting with positional play

First AI try  From the tactical problem set of 1430 I have absorbed 251 problems (22%) since May 5th. This means that 1.4 problem per day is a realistic speed op progress for me. The Woodpecker method goes at a speed of 1 problem per day, if I reckon well. So nothing abnormal here, just going 1.4 times faster. Which is not so strange since I'm retired. The 7 circles of hell is almost identical to the Woodpecker method and was administered at the same speed. I become tactically stronger, I can feel that. Absorbing 251 problems should already lead to a measurable effect Elo-wise, I guess. But immediately the two other holes in my bucket start to leak much more: positional play and endgames. So I decided to start with a positional problem set too, next to my daily tactical routine. Why positional play before endgames? Mainly for the following reasons: Poor positional play shows itself in excessive time and energy usage in the beginning of the middlegame, when the position doesn't ...

Accidental extras

Image
 When you limit yourself to a fixed amount of 1430 problems and try to get deeper instead of broader, you can't help to start noticing new analogies every time. A combination can often be divided in a trivial part and some accidental extras. The trivial part is not going to gain you wood, but the accidental extras might do so. White to move r1rn2k1/3q1ppp/5n2/2b1R3/p1NB4/P2Q1N2/5PPP/1R4K1 w - - 0 1 #144. Fressinet, Laurent vs. Dorfman, Iossif chessable 1001-chess-exercises-for-club-players Let's first have a look at the trivial part: White to move Within the position you can recognize a knight fork. "Usually" such fork would gain you an exchange. But the attacking square is covered by the black defender Bc5. You can remove the black bishop by sacrificing your rook for it by 27.Rxc5 Rxc5 .  White to move You invest an exchange to remove a defender in order to be able to execute a fork to gain an exchange. "Normally" that would level out. But it are the "...

What is a combination made of?

Image
 [disclaimer] You will often see positions that I have used before. But since my insights are new, that very fact is not relevant. Since I repeat them all the time, I can't remember that anyway. White to move 3r3r/1pk2p1p/2p1p1p1/b2n1q2/3P1P2/P1PQ3P/2BB2P1/3R1R1K w - - 0 1 #241. Van Dijk, Harold vs. Polak, Alexander Chessable course  1001-chess-exercises-for-club-players What is this combination made of? The main ingredients are two discovered attacks, who function side by side and are influencing each other. discovered attack of c3 and Bd2 against Nd5 and Ba5 (blue arrows) discovered attack of Bc2 and Qd3 against Qf5 and d2 (green arrows) Notice the unusual target d2. It is in fact a defensive target. You might think, "duh, 20 scenarios is not much", but it are these kind of subtle differences that make the study worthwhile. Targets can be anything! White to move It al starts with the first discovered attack. 1.c4 threatens two targets, the black Bishop and Knight. It i...

Separate the goal from the price tag

Image
A combination must be judged by what the total of subtasks accomplishes.This means that worrying about the price tag of an isolated subtask will only distract you.  White to move r3rk2/2pb3Q/2q2bp1/2n1p3/1pP1P3/1B2RN1P/P4PP1/3R2K1 w - - 0 31 Salgado Lopez, I. vs. Granda Zuniga, J. Quito 2012 Chessable 1001 Chess Exercises for Advanced Club Players. White has sacrificed a bishop for two pawns and an attack 31.Nh4 Bxh4 32.Rf3+ Bf6 What has white accomplished, and what has been the price tag?

Why would you even think of it?

 Why would you even think of Rxe5 instead of Bxe5+? White to move 1r2r3/p5pp/2nk4/1R1pp3/P2P4/2P3B1/3K2PP/4R3 w - - 0 1 1.Rxe5 introduces the following duplo attacks: discovered attack Re5 plus Bg3 against blacks King and Re8 (loading the battery) skewer Bg3 against black King and Rb8 Furthermore, if black takes on e5, he puts himself into a pin (another duplo attack). So apparently, the application of duplo moves is stronger than the straightforward short-term threat Bxe5+
