Zugzwang
Key Concept
Any move the opponent makes worsens their position
How This Tactic Works
Zugzwang (German for 'compulsion to move') is a situation where the player whose turn it is would prefer to pass — any move they make worsens their position. Zugzwang is most common in endgames, particularly king and pawn endings where opposition determines the outcome. Whoever is 'in zugzwang' must make a concession: move the king off a key square, advance a pawn prematurely, or allow a decisive breakthrough. In rare cases, zugzwang appears in the middlegame, often in fortresses where the defender has no safe moves. Recognizing and creating zugzwang is a hallmark of strong endgame technique.
