What is a zugzwang?
Zugzwang wins by giving the opponent the move when every legal reply worsens their position. It is the signature weapon of pawn and minor-piece endgames.
How to spot it
In simplified positions, ask what the opponent would play if forced to move. When every answer loses, engineer that exact position — often with a quiet waiting move.
What this set trains
These puzzles build endgame patience: winning with tempo and geometry instead of direct attack.
