I have implemented this into Phalanx XX too. I was inspired by Crafty :-). I give penalty to knight rather than bonus to bishop and do so in all endgames, not just B vs N. It is weak knight (that cannot play on both sides of the board), all other pieces are strong against the N in endgames with pawns on both sides of the board. I also add function of file distance between leftmost and righmost pawn to the penalty. Dusan Dobes
