Maybe 27 ... e5 is the decisive mistake. Crafty prefers Kf8 instead:

21-> 105:50  -0.35   1. ... Kf8 2. f4 Ke7 3. Kg2 Kd6
4. Kf3 Kd5 5. f5 exf5 6. Kf4 Ke6 7. Kf3 Kd6 8. Ke2 Ke5 9. Kf1 Kd5
10. h3 Ke4 11. Kg2 a5

...e5 gets a much lower score. Haven't looked at it closely though...

Anyway, I play to get draws versus these programs. I think your game
was an excellent example on how to disarm the programs: play it simple
and trade pieces unless there's a specific reason not to. If black hadn't
played bxf3, there would have been a position where white had a knight
against a bishop and white could put its pawns on the opposite color.
I have quite a few draws of this type against comps. But you won,
even better.

To cheat the program on a win gives a special pleasure :)
