Oops, pushing buttons too fast.
I don't have the version anymore that I used before. The current version behaves
similar:
Considering moves Kd6 and Kd7 on shallower depth with an advantage for black.
This changes on depth 16:
depth 16 (59 secs on same machine): score -54, move Kd7
From depth 17 on Baron is looking at Bb7 with a score of -54, changing to Kd7
again at depth 21 (111 secs). At depth 22 the score gets closer to a draw and at
depth 24 (586 secs) the score rose to -8:

1..Kd7 2.Kd4 Kd6 3.g7 Bg8 4.b7 Kc7 5.Kc5 Kxb7 6.Kd6 Bh7 7.Ke7 Kc6 8.Kxf6 Kd6
9.Kg5 Ke5 10.f6 Bg8 11.Kg6 Ke6

Hope it helps,
Richard
