Learn How to Win a Chess Endgame: Zugzwang
This chess endgame is a classic zugzwang puzzle: the side to move is under pressure because almost every legal move worsens the position. In pawn endgames, king activity and pawn structure matter more than material count, and a single tempo can decide everything. Here, the kings are active, the pawns are fixed, and the side to move must find a precise defensive resource or allow a decisive breakthrough. Understanding opposition and pawn breaks is essential in classical chess endgames.
