Chess960, or Fischer Random Chess. is a chess variant invented by the late former world champion Bobby Fischer. He modified the rules of Shuffle Chess in such a way that castling possibilities exist for all starting positions.
It was originally announced on June 19, 1996, in Buenos Aires. Fischer's goal was to create a chess variant in which chess creativity and talent would be more important than memorization and analysis of opening moves. The initial position is set up subject to certain rules, resulting in 960 possible initial positions, hence the name 'Chess960'.
Chess960 differs from Chess only inasfar the initial set up of the pieces is concerned. After that, the game is played in the same way as regular Chess. In particular, pieces and pawns have their normal moves, and each player's objective is to checkmate the opponent's king.
The starting position for Chess960 must meet certain rules. White pawns are placed on the second rank as in regular chess. All remaining white pieces are placed randomly on the first rank, with the following restrictions:
Note that the king cannot occupy a cornersquare because there would be no room for a rook. The starting position can be generated before the game by for instance a computer program or dice.
Rules for castling
Chess960 allows each player to castle once per game.
Castling however differs substantially from regular Chess, yet the outcome is forced into a Chess-like configuration, with the king on c1 (c8) and the rook on d1 (d8) in 'C-castling', notated as O-O-O, and the king on g1 (g8) and the rook on f1 (f8) in 'G-castling', notated as O-O.
It is recommended that a player state "I am about to castle" before castling, to eliminate potential misunderstanding.
Castling may only occur under the following conditions.
In consequence of these unusual castling rules, in some starting positions, the king or rook (but not both) may not move during castling.
Note: with due reference to "Why do great players make poor inventors?", in the Pit the Chess960 applet has three 'modes', depending on the presence, and if, nature, of castling:
Note: All castling is 'CG-castling'
