A shuffled back rank to counter strong opening knowledge. Aka Fischer Random Chess.
Chess 960 derives its name from the 960 possible unqiue starting positions. The the home ranks are randomized, within some limitations, which makes it distinct from standard shuffle chess.
Invented by world chess champion Bobby Fischer in effort to improve the game by breaking the dependency of experienced playerProfiles on opening theory.
Pawns are placed normal, but the home rank is set up in 1 of 960 possible variations within the following rules.
White and black home ranks pieces are set up identically, including the King and Queen facing each other on the same file.
Rather than moving two squares along the home rank, the King must move to either side of the Rook regardless of how many squares are vacant between them.
When the King and Rook are adjacent to each other the King must be placed onto the Rook to initiate the castling.
Unlike Standard Chess, it is possible to Castle on the very move in this variant!En passant rules remains the same as Standard ChessCheck and Checkmate rules remain the same as Standard ChessStalemate conditions remain the same as Standard ChessDraw conditions remain the same as Standard ChessWinning conditions remain the same as Standard Chess
