Most programs will probably find Kd7 as the best in this position. But the key is the right move sequence and the drawish (near 0) score for this move. As human I guess that correct line is something like 1...Kd7 2.Kd4 Kd6 3.g6 Bg8! 4.b7 Kc7 5.Kc5 Bh7 6.b8=Q+ Kxb8 7.Kd6 Kc8 8.Ke6 Kd7 9.Kxf6 Ke8 10.Ke6 Bg8+ 11.Ke5 Ke7 and white can not win... My Bestia will find Kd7 at ply 12 with positive score, than fails low at ply 17,18,19, gets score -171 and finally find the draw(score 0) at ply 24 with the following PV: e7d7 d3d4 d7d6 g6g7 d5g8 b6b7 d6c7 d4c5 c7b7 c5d6 g8h7 d6e7 b7c6 e7f6 c6d7 f6g5 d7e8 g5h6 h7g8 h6g6 g8f7 g6g5 e8e7 g7g8Q f7g8 On my rather slow AMD K6-2/450MHz it needs around 1 hour to find the draw but even here it will play correct moves for black even at rapid time control ~20sec/move(hardest move is 3...Bg8 - 22sec).
