Antichess is a chess variant where you win by losing all your pieces, or in many rule sets by having no legal move. Captures are compulsory, which means your opponent can force you to take their pieces, and that is what makes the game harder than it sounds. Confirm the exact rules on the site or board you use.
The Usual Rules
- Pieces move as in standard chess, including castling in some rule sets and not in others.
- If a capture is available, you must make one. If several are available, you choose among them.
- The king has no special status. It can be captured, and there is no check or checkmate.
- Pawns can promote to a king as well as to the usual pieces.
- You win by having no pieces left. Many online rule sets also count a stalemate as a win for the stalemated side.
Because variants differ on castling and stalemate, read the rules before playing.
Why It Is Harder Than It Looks
It seems easy to just throw pieces away, but the opponent is also trying to lose. That means each side tries to offer pieces in a way that forces the other to capture, not the reverse.
Compulsory capture creates chain reactions. A single offered pawn can drag a rook across the board, open lines and set up a second forced capture. Players who plan these forcing sequences often win material, in the sense of getting rid of it, much faster.
Core Ideas
- Count forced captures. Before every move, look at which captures your opponent will be obliged to make after it.
- Keep your pieces mobile. Pieces stuck behind pawns may be forced to remain on the board when you want them gone.
- Use sacrifices to open lines for your own pieces to be captured.
- Be careful with the last few pieces. A single remaining piece that your opponent cannot attack can stay alive for a long time.
- Watch for stalemate wins if your rule set allows them. Blocking your own pieces completely can be a goal.

The Short Version
Antichess reverses the goal of chess, but compulsory captures make the game tactical and surprising. Count forced captures on every move, keep your pieces free, and verify the stalemate and castling rules of the version you are playing.
