King e8; Empress a8; Knight b8; Bishop c8; Amazon d8; Queen f8; Princess g8; Rook h8; Pawn a7, b7, c7, d7, e7, f7, g7, h7.
Empresses have the combined moves of rook and knight; amazons have the combined moves of queen and knight (i.e., of bishop, rook, and knight); princesses have the combined moves of bishop and knight. Pawns can promote to empress, amazon, princess, queen, rook, knight, and bishop. Kings can also castle with an empress. All other rules are as in orthodox chess.
