Zugzwang (move compulsion) is a chess term. It is the tactic of taking advantage of the fact that you cannot skip your turn in chess, you are forced to move into a bad position, leading to your defeat. It usually occurs in endgames, which I'm terrible in. Here is the most famous example:

.
Black is forced to move from the promotion square, to the white square on 7th row, allowing the white king to move to 7th row and protect to the promotion square and then go on to promote the pawn and win.

It was promoted from a technical chess term to a term used in the real world. Zugzwang might mean if you force someone to act, when it is in their best interest not to act.
