papillon77: I'm translating, it looks like an interesting variant:

Tutti frutti chess is a chess variant invented by Ralph Betza and Philip Cohen in 1978.

There are three pieces that are not used in conventional chess:
PRINCESS: bishop + knight
EMPRESS: Rook + knight
THE AMAZON: queen + knight

The amazon is placed in the usual location of the queen (column D). The queen herself is now on the other side of the King (column F), Princess right next to the queen (column G) and Empress on the same side of the King as the amazon (column A). The only knight is on the left column B, the only bishop on column C and the only rook on the column H.
The pawns are placed as in regular chess.

In short, the piece set-up is (white) : ENBAKQPR

The pawn that reaches the last row (from the perspective of the players) is promoted to rook or bishop or knight or princess or queen or empress or amazon.

The King can castle with the Empress in accordance with the rules of castling (if the Empress has made any previous move, castling is not possible)

All other rules are the same as classical chess.
