Zugzwang is a position where the player to move is worse off because any legal move weakens their position. It is especially common in chess endgame positions with kings and pawns. Recognizing zugzwang helps you convert small advantages into wins.

How do I win a pawn endgame in classical chess?

Focus on king activity, pawn structure, and opposition. In many pawn endgames, the active king can escort a passed pawn or invade weak squares. A well-timed pawn advance can also force the opponent into zugzwang.

Check whether the defender has any useful waiting move. If every king move or pawn move creates a new weakness, the position may be lost. Endgame puzzles often hinge on this exact idea, especially with isolated or backward pawns.

What should I look for in a master vs master endgame puzzle?
