Here is the C.A.P. record for that position: rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - acd 15 acn 326985707; ce -7; pv e4 e6 Nf3 Bb4 Nc3 Ne7 Bc4 Nbc6 O-O O-O d4 Bxc3 bxc3 Na5 Bb5; pm e4; id "C.A.P. 445907"; I had better warn you that if anyone starts yelling about black's opening advantage (like on the crafty list server) I'm going to scream. Fortunately, none of you are likely to hear it. You are simply not going to get a very good evaluation from a computer on the opening position. It takes quite a while to develop a good, solid position and computers like to hunt for tactical things. Until you get out of the openings, computer analysis is really going to pale compared to human analysis most of the time. Of course, it is an interesting exercise. I have found that (at least with some older versions) if you let crafty play without an opening book, it liked to play the Sicilian defense (dragon version). I wonder if there are any engines that will play the Orangutan if left on their own? ;-)
