Chess960, (or Fischer Random Chess) a chess variant invented by former World Chess Champion Bobby Fischer, introduced on June 19, 1996 in Buenos Aires, Argentina. Randomizing the pieces on its back rank has been known as Shuffle Chess, but Chess960 introduces rules so that castling options are retained in all starting positions, one player's bishops must start on opposite-color squares, and the king must start on a square between the rooks, resulting in 960 unique positions, while the classical initial position is one of them. Chess960 practically handicaps the application of opening theory in classical chess with the memorization of opening moves, both for human as well for chess programs.
