[D]6k1/8/7P/3pK3/8/8/2B5/8 w - - 0 1 As most of the others, my program knows that KBP-K with a rook pawn and bishop of wrong colour is drawn if some conditions are met. In the position given above black has also pawn and the position remains a theoretical draw. Now, my program evaluates it as +3.5 and refuses to capture the black pawn. Of course I could add this special case too but there are lots of other combinations of pieces I had to add too. Did someone try a more general attempt to solve this problem? Would the following rule work in this case? If White is ahead in material and if it is a drawn KBP-K position after removing all black pieces, the position is a draw. The problem are IMO possible Zugzwang positions which could occur, at least in other types of drawn endgames with big material imbalance, e.g. KQ-KP. In this case a theoretically drawn position could converted to a lost in some cases if a black piece is added.
