A couple of dubious moves from Gromit in a advantageous position gave Crafty the full point. Could anyone check out the evaluation after 25... Be7. I can't believe that 26. f4 is the best move.
Best wishes...

I will take a look at the game.

I ran the position after 25... Be7 through some engines and got the following results:
Gromit likes 26.f4 at depth 9, but changes to 26.c4 with eval +2.5.
Crafty 17.8: 26.g3 +2.2 (depth 10)
LG2000v2: 26.g3 +2.14 (depth 10)
SOS 11/99: 26.g3 +2.66 (depth 10)
Fritz 5.16: 26.Rg3 +1.94 (depth 11)
I don't know if this helps.
Best wishes...

With a newer version of Gromit3 I get the move c4 at ply 7 and Gromit didn´t change his mind till ply 11. Mainline is c4, Rd6, Rg3, Qd2, Nf3, Qb4
Score was about +2, I didn´t remember exactly.
The move f4 was bad and I hope it was played due to some minor bugs that we have fixed in the actual version.
What a pity to throw away this good position against Crafty with f4

I'll run a few more tests with long time control during the night. If I stumble over a blunder I'll let you know. Even though Crafty is a strong engine to test against, it's the least likely candidate for a blunder move.
