Regole di Chess

Objective: checkmate the opponent's King — put it under attack with no escape.

Pieces and moves: King (1 square in any direction), Queen (any number of squares in straight line or diagonal), Rook (any number of squares in straight line), Bishop (any number of squares diagonally), Knight (L-shaped: 2+1 squares, jumps pieces), Pawn (advances 1, captures diagonally; first move may advance 2).

Special rules: castling (King and Rook swap under specific conditions), en passant (special pawn capture), pawn promotion (reaching the opponent's first rank, promotes to any piece except King).

End of game: checkmate (loss), stalemate (draw if player is not in check but has no moves), draw agreement, or on time expiry.
