The game is played using a standard chessboard, and follows all the rules and conventions of standard chess, with one difference: the queen's rooks are replaced by empresses (rook plus knight), the queens are replaced by amazons, the king's bishops are replaced by queens and the king's knights are replaced by princesses. All other pieces are unchanged. A king may castle with a rook or empress, and pawns may promote to any piece that was on the board at the beginning of the game except the king (amazon, queen, empress, princess, rook, bishop, or knight).
