Im sorry i still dont follow, the puzzle has ended yet there is no result, and i cant see one resulting to quickly from this situation. perhaps i am missing something.
But i see a Black King sitting on a Black square who is out of check, with two potential moves to make, on of which would land him on a black square, leaving him safe from the white bishop on a white square and a few pawns. White hasnt won this puzzle yet has it?
