About Chess960

How the position is chosen

Bobby Fischer proposed Chess960 in 1996 to take memorised openings out of the game. The pawns start normally, but the back-rank pieces are shuffled under three rules: the bishops must sit on opposite colours, the king must stand somewhere between the two rooks, and Black's setup mirrors White's.

Those constraints leave exactly 960 possible starting positions — one of which is ordinary chess. Every game asks you to evaluate a fresh position from the first move.

Castling in Chess960

Castling exists but ends in the standard squares regardless of where the king and rook started: king on g1/g8 with the rook on f1/f8 for kingside, king on c1/c8 with the rook on d1/d8 for queenside. The usual conditions apply — neither piece has moved, the squares between are free, and the king never passes through check.

Everything else — en passant, promotion, checkmate, the fifty-move rule — is unchanged from FIDE chess.
