Game only with pieces, that would be colorbound on normal board.

I've not seen the idea of imposing colorboundness on all pieces but removing it by the odd number of files on a cylindrical board, thought I recognize component ideas. A small quibble about promotion: Promotion to a Knight is needed in FIDE Chess, as its moves are not a subset of the Queen's move. In some positions, the Knight can checkmate when the Queen can't even check. This factor does not apply to this game; but there is one case where underpromotion to Rook or Bishop in needed (rather than merely allowed) in FIDE--when promoting to Queen would result in immediate stalemate, but the lesser promotion could force checkmate on a subsequent move. With three combination pieces to choose from, it is much less likely in this variant, but analysis is needed to determine if it is possible: if so, underpromotion must be allowed (if and only if stalemate is a draw).
