This is one of the newest chess variants that is played in AISE,
the Italian Chess Variants Organization. The game was proposed by Fabio
Forzoni in 1995. First an informal tournament was held, and the first `official'
tournament of this variant was played in the AISE `GRAND PRIX' in 1997.
Each piece (except a king or a queen) that captures another piece promotes
in the following order: Pawn > Bishop/Knight > Rook > Queen. A
queen that captures stays a queen. A pawn that captures promotes to a bishop
or a knight to the choice of the player that makes the capture (i.e., that
owns the pawn.) I.e., a knight or bishop that captures instantly promotes
to rook, and a rook that captures transforms directly into a queen.
Kings do not promote when they capture. One may not castle with a promoted
rook.
After a piece have been promoted to queen, that queen may not move
further for the rest of the series of that turn.
A pawn that reaches the eigth row, either by capture or a move without
capturing, promotes only to bishop or knight, to the choice of the player
owning the pawn; i.e., the pawn may not promote by that move to queen or
rook, even while it reached the promotion row.
A piece can make more than one promotion during a turn.
Sample games
Here are the first two experimental games ever played in this variant.
