Crafty 19.3 ends up in this position
white black
1 d5 e5
2 c6+ bxc6
3 bxc6+ Kc8
4 d6 e4
5 Kd4 h5
6 g4 hxg4
7 hxg4 f4
8 Kxe4 ...
[D]2k5/8/2PP4/6p1/4KpP1/8/8/8 b
21-> 1:40 6.47 1. ... Kd8 2. Kd4 Kc8 3. Kd3 Kd8 4.
Ke4 Kc8 5. Kf3 Kd8 6. Kf2 Kc8 7. Ke2
Kd8 8. Kd3 Kc8 9. Kc3 Kd8 10. Kd2 Kc8
11. Ke1 f3
Seems that crafty isn't doing any progress and score is totally wrong :-(
