Antichess is a chess variant in which the objective is reversed: the player who captures the opponent’s final piece wins. Captures are mandatory, which removes quiet positional play and turns every game into a forcing tactical sequence.

Core Rules

Play starts from the standard initial position. A player must capture when at least one capture is legal. When several captures are possible the player chooses which one to make. Only when no capture exists may a non-capturing move be played.

The winner is the player who either captures the opponent’s last piece or leaves the opponent with a lone king that has no legal moves. stalemate therefore counts as a win for the side that produced it.

check and checkmate do not exist. The king is treated like any other piece and may be left in attack or captured.

How the Game Differs from Standard Chess

Because every capture must be executed, pieces cannot be defended in the ordinary sense. A protected unit can still be taken; the opponent simply decides whether to accept the recapture. This eliminates most manoeuvring and forces both sides to calculate long chains of forced captures from the very first moves.

Kings lose their royal status and become active fighting units that can be exchanged like knights or bishops. As a result, endgames revolve around pawn promotion races and the careful management of remaining material rather than mating attacks.

The opening phase is unusually concrete. Players often steer toward positions in which the opponent is left with only unfavourable captures, rapidly reducing the board to a handful of pieces where every move remains compulsory.
