Mine penalizes the score like this:
oppBishopMultiplier = min(16, (OPPCOLBISH + diffPawns + diffPassers +
howManyRunners + HOWMANYWHITEPIECES +
HOWMANYBLACKPIECES));
score = ((score * oppBishopMultiplier) >> 4);
OPPCOLBISH is a constant.
diffPawns and diffPassers are absolute differences in the number of pawns and
passers. howManyRunners is how many passed pawns can't be stopped by the
opposing King. So the more of these things there are, the smaller the reduction
applied to the score. Obviously this isn't efficient or fast, but that's quite
typical of the rest of PM anyway :-)
