infoIn the recent TCEC game between Laser and Booot a opposite bishop KBPPKB endgame arises which was draw. Laser could detect it but not Booot. Stockfish also can't detect the draw (score > 1). So add to the KBPPKB endgame function following case. If one pawn is on a or h file and promotion is covered by the king and the other pawn is covered by the bishop the position is draw.
