Two Pawns vs One: Converting the Pawn Majority

White to play and win

Play

Two pawns against one, and the position is won, but not by pushing b6. His king guards the b-pawn's path and fights for the opposition. Your king has to walk round and drive his king back, step by step. The pawn break b6 comes last, when it takes a square from his king.

The theory

Watch the method: press play to see the winning idea run, or step through it move by move.

First, why not b6 now? His king simply takes it. The a-pawns block each other, and the game is a draw.

Almost every winning endgame passes through a pawn majority somewhere, and 2 vs 1 is the majority in its purest form. The position is completely winning, and the single most natural move in it is the only real way to spoil everything.

Why the break waits. Your b-pawn is already passed, and shoving it to b6 looks like the obvious way to cash the majority in, which is exactly why the break looks compulsory. But played immediately it just hangs: the pawn arrives on b6 unprotected, the defending king removes it, and the remaining blocked a-pawns are a handshake. A pawn break is not an achievement in itself; it is a liquidation, and liquidations are timed by where the kings stand.

The king does the winning. With the break held in reserve, the defending king lives under a permanent double duty: it must stay in touch with the b6 square AND meet your king's march. It cannot do both. Your king outflanks on the kingside first, d3 to e3 to f3 to f4, and only then comes back through e4 and d4, gaining ground every time the defender chooses one job over the other. This is the principle of two weaknesses in five pieces.

The timed squeeze. Once your king reaches c6, b6 transforms from a trade offer into a crowbar: the defending king is pushed onto the back rank, your king turns around to harvest a5, and the surviving b-pawn promotes with a textbook king escort. Take the opposition, seize the square in front of the pawn, and use the spare a-pawn tempo if you need it. Note which pawn does the queening: the knight pawn, not the rook pawn. Trading down to the a-pawn alone would resurrect the corner fortress you already know, which is one more reason the move order is the entire game.

Break at the wrong moment and it stalemates. The timing is not a nicety, it is survival. Play the b6 break before your king has boxed his in, or with his king a step too free, and after the pawns lock he has a stalemate refuge in the corner: no legal move, and the half point escapes. The break is the last move of the win, never the first.
