Hecatomb chess was been invented by Kevin Maroney

Each player has thirty one queens and one king .

The kings are positionned as a standard chess (white e1 and black e8) . The other squares each contain a queen (white of the first four rows , except e1, black on the last four rows , except e8 )

Apart from the particular opening setup , the game is played following all applicable rules of standard chess

Do not merge with Knight mate chess

The queen replaced by amazon , the bishops by cardinals , and the rooks by Marshalls (in move , amazon = queen and knight , marshall = rook and knight , cardinal = bishop and knight)

There is no a castle

Pawns can be promoted on a knight , rook , queen or bishop , as a standard chess

tutti frutti chess was invented in 1978 by Ralph Betsa and Philip Cohen . There are nine different pieces (each player starts a game with eight pawns (placed on their standard Chess positions) , one Amazon (on the D column) , one Marshall (on the A column) , one Cardinal (on the G column) , one queen (on the F column) , one rook (on the H column) , one bishop (on the C column) , one knight (on the B column) and one king (on the E column) .

In move , Marshall = knight and rook , Amazon = queen and knight , and Cardinal = bishop and knight

The king cas castle with the marshall , following standard castling rules

When a pawn reaches the last row (from the player's point of view) , it can be promoted to a knight , a rook , a bishop , a queen , a marshall , a cardinal or a amazon

The other rules are the same as for Standard chess
