There are several variants of this game, all are different from the now played and said traditional chess.
Some of them are played on different sized boards, some of them on non-quadratic boards, there are some variants which are played with different pieces, and of course always with different rules.
Actually the Fischer Random (Fischerandom, FR, FRC, Chess960, C960) variant is supported in the club.
Bobby Fischer (Robert J. Fischer) the earlier chess world champion worked out this variant in 1996.
It's played on the same board with the same pieces as the traditional chess, only the order of the pieces is different.
Pawns are located on the 2nd and 7th rank, pieces on the base rank as well, but their order is different, random. It's not sure, that the rooks occupy the corners of the boards, it's possible that other pieces will take place their.
It's sure that both players have bishops on different colors, and the kings are located between the rooks (so they can castle). Ensuring the same chances black starts with the mirrored setup.
The learned opening rows, variations are less important here, because the pieces are on different squares, and there are 960 different initial setups.
Fans of the Fischer Random chess say, here creativity and talent is more important than memorization and analysis of opening moves.
