One could probably find easy rules for certain wins (say several pieces, that are not all the Bs of the same color, and no immediate stalemate, perhaps more is needed). There will be some draws, that could be detected rather easily (4 rook pawns, defending K close enough to the corner. pawns of the color of the promotion square could be Bs.). For probably any "practical" situations, that will not be covered by the rules, a very shallow search will help. If the evaluation returns +15 or some mate score will not matter (unless one wants to find the shortest mate fast). Regards, Dieter
