Fix KBPK bug With position fen 7k/8/8/8/8/7P/6K1/7B w - - 0 1 go depth 25 The evaluation at depth 22 is not draw as it should be. The reason is that when search reaches the position 8/6kP/8/8/8/3B4/6K1/8 w - - 0 1 if white plays h8R or h8N then we get a position that is a "KNOWN_WIN" and is _not_ a check, so futility pruning in qsearch kicks in and black may think that it is "futile" to reply Kxh8 since, according to the logic of the code, it cannot raise the score back towards a draw. bench: 4728533
