Zugzwang
German for "compulsion to move": a position where any legal move makes things worse, and the only real wish is to be allowed to pass — which chess never allows.
Key Ideas
- Chess has no "pass" move — a player in zugzwang must move even though every option worsens their position.
- Overwhelmingly an endgame phenomenon, since there are fewer pieces around to create a safe, neutral move.
- Mutual zugzwang describes a position where whoever has to move next, of either color, is worse off.
- A core tool for converting small endgame advantages into full, decisive ones.
How It Works
Zugzwang, borrowed directly from the German for "compulsion to move," describes a position where a player would be perfectly happy doing nothing at all — but chess offers no such option, and every available legal move actively damages their own position.
It is overwhelmingly an endgame concept, since fewer pieces on the board means far fewer "safe," neutral moves are available to simply mark time — a king or pawn move that does nothing bad is often nowhere to be found.
The opposition technique described elsewhere in this guide is really just a specific, common form of zugzwang: the side forced to break the standoff between the kings is, by definition, the side put in zugzwang.

A recurring endgame decider
Zugzwang is one of the few chess terms borrowed wholesale from another language into standard English chess vocabulary, a testament to how central the concept is.
