Zugzwang (from German 'compulsion to move') is a situation found in chess and other turn-based games wherein one player is put at a disadvantage because of their obligation to make a move; a player is said to be "in zugzwang" when any legal move will worsen their position.
Here you can see an example of mutual zugzwang - the one who makes the first move loses (as a reminder not to raid :D)
