Take on b4, take on b3, check on a2.

Yeah. Definitely not easy for a blitz game.

Bd3, take on b2, promote.

A chess position. FEN = r4rk1/pp4q1/2nNb3/2P2p2/5R2/PN1p4/1PQ2KP1/R7 w - - 0 27

From yesterday's game at my club. Black just played 26...d3 and thought he was winning. I believed him, played 27.Qd1 and lost a few moves later.
What did we both miss?

You can take the pawn on c3?

You cannot win a game after resigning. So, let's take the rook and hope for Bg6. The pin is not deadly, you still have a check with the rook on f2.

A chess position with FEN-code r2q1rk1/pb3p1p/1p2pnp1/8/3QP3/1P4P1/PN3PBP/2RR2K1 w - - 0 17. White to move.

What is the best move for White according to Stockfish here?
I did not play it and it was not even on my list of candidate moves.

I still won my game by the way, but only thanks to a blunder from Black in an equal rook endgame.

I like to play Bc2 to attack the undefended rook on b1. For that the horsey has to go. So, let's eat that pawn on e5.

Black is an exchange down, but the White king is very weak. So, first candidate move to look at is 1...f5 with ideas like 2...Qg5.

But can I call it "the chess speaks for itself"?

Solving a Wotawa-study in 60 seconds is only possible if your name is Stockfish.

That position is from a Nezhmetdinov-game, right? Very beautiful.

Qe6 looks nice, but has a small problem. So, let's start with 1.h4 intending Qe6.

Take on b5, play a5 and enjoy the rest of the game.

It is a nice move, but isn't Nb6 just losing a piece?

First candidates for me would be Ne5 or even start with a5, preventing Black to play this, but I don't like White's position. So maybe even Ne3 is an alternative.

18.08.2025 07:00 β€” πŸ‘ 1    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

I see a threat on a1, so let's start with a check with Nf6+. Black takes and then don't autopromote to a queen.

But aren't you underrated now?

A nice example of rule 1 as well. :) Too bad you did not win this one.

You're welcome.

I think in general there are a few rules in pawn endgames:
1) If possible, don't enter a pawn endgame. Too difficult. :)
2) Activate your king first. And prevent your opponent doing the same.
3) Leave the pawns where they are, so you have some reserve tempo later.

Take on f5, put the king on f4, Black has to put his king on f6 to defend the sitting duck, win with the queenside majority.

Why don't we start with Kh3 and only after ...f5 or ...h5 we play g4. That e4 pawn seems to be a sitting duck indeed.

29.07.2025 21:10 β€” πŸ‘ 1    πŸ” 0    πŸ’¬ 2    πŸ“Œ 0

I like 1.Qe4 and Black has some issues.

28.07.2025 19:53 β€” πŸ‘ 2    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

Yeah, that gives Black a clear advantage.
But according to the engine there is even a better (winning) alternative.
