There are a number of games based on chess with rule variations, and these are referred to as ''chess variants''. One of the most popular of these is ''Bughouse'', a partner-based game in which a player who captures his opponent's piece can give it to a partner on another board to drop on a square of his choosing. Another is ''Kriegspiel'', a game in which a player can see his pieces but not that of his opponent. [http://www.chessvariants.com/incinf.dir/kriegspiel.html] A simpler variant is ''Antichess'', which is also called ''Suicide chess'', in which a player must make a capturing move if any legal captures exist on the board, and in which the goal is to run out of pieces first.

In 1996 American grandmaster and former world champion Bobby Fischer introduced a variant called Fisher Random Chess, which involves scrambling the positions of the pieces on the first and eighth ranks before starting play. A number of rules govern the precise manner in which the pieces can be arranged; for example, the king must be somewhere between the two rooks, so that castling to either side is still possible, and the black and white positions must mirror one another. The rules provide for 960 possible starting positions, and for this reason the game is sometimes called Chess960. Fischer hoped his variant would encourage creative thinking and avoid the memorization associated with opening play in modern chess.
