Zugzwang
Zugzwang (German for "compulsion to move") is a situation where a player would prefer not to move at all, as any legal move worsens their position.
Key Concepts
Obligation to Move
In chess, you must make a move on your turn, even if it harms your position.
Position Deterioration
Every available move makes the position worse.
Endgame Occurrence
Most common in endgames, though it can occur in middlegames.
Types of Zugzwang
- Mutual Zugzwang: Both sides would prefer not to move
- Pure Zugzwang: Only one side is in zugzwang
- Reciprocal Zugzwang: The position changes based on who moves
