Some chess variant inventors have done efforts modifying F.I.D.E. chess to make Bishop more powerful. One of the methods is to modify the shape of board and setup. King Arthur's Chess 72 has a round or cylinder board with an odd number of files which unbind Bishop with colors. Balbo's chess, Longshanks Chess, and Troitzky Chess (their objects may not be to strengthen Bishop) have similar methods that rotate the board by 45 degree to make a diagonal square board. But players are playing corner to corner. Every pawn has a different distance to promote. The setups are very different from F.I.D.E. chess, and castling doesn’t exist. Left and Right corners that Pawns can not cover become very important. There may be other variants that I haven't noticed.

Diagonal Oblong Chess invented by Shi Ji is another experiment by modifying the shape of board. A similar board with different size was used in UOS. There are 64 cells as the same to F.I.D.E. chess. Players are playing side to side. The setup is similar to that of F.I.D.E. chess. Pawn rules are similar to those of Diagonal Chess and Double Diamond. Pawns can promote by moving by an equal distance and they can cover every file. Bishop becomes colorbound Rook, and Rook becomes colorfree Bishop. There are also castling & guarding rules, but slightly different from that of F.I.D.E. chess.
