Go up one level in this thread
the white and black pawns are disjunct, obviously there is no one-bit in the white pawn BitBoard that is also set in the black pawn BitBoard - and each of the two BitBoards are unique for each pawn position, so the difference is IMO also unique. The only thing to do is a 64 bit subtraction with masking the 48 relevant bits via shift/and - not a big task and not worth to do it imcrementally. Gerd
