Questions about variants of normal chess including bughouse, Chess960 (Fischer Random), atomic chess, and antichess.

A chess variation or chess variant is a game which is based on chess, but has different rules and/or layout and/or gameboard.

Some common chess variants include:

  • Chess960 (also known as Fischer Random Chess): the pieces on White's first rank are randomly placed (though the Bishops must be on opposite-colored squares and the King must be between the Rooks), and Blacks setup mirrors White's. The rules are the same as in standard chess.

  • Bughouse: a game with a partner with opposite colored pieces playing against another partnership. Pieces captured on your board are given to your partner, and he or she may place the pieces "in hand" on his or her board in lieu of moving a piece.

  • "Cousins" of chess that are played in specific regions of the world, such as Shogi in Japan and Xiangqi in China.

  • Displacement chess: a family of chess variants in which the rules are the same as in standard chess, but some of the pieces in the first rank of each player are transposed. Similar to Chess960, but not random.

  • Atomic chess: a capture results in an "explosion" which removes (aka. "kills") all pieces in any of the eight surrounding squares, except for pawns, including the captor.

  • Antichess: the goal of antichess is to force your opponent to capture all of your own pieces. Similar to checkers, if there is a legal move that captures a piece, it must be made. Check is ignored - the king is captured like any other piece.
