I fixed the (non-historical :) spelling error in the subject line. No worries.

Can you provide the updated CAP analysis in that line?

Yes, it's important. This is why I'd like programs to have 2 spots for assessments: the first holds a raw, computed score, and the second is used for minimaxing backup (backsolving in Bookup terminology.) That way, when you see a position with highly different values you can explore deeper into the continuation and see if a good move wasn't analyzed later. >experiment. It also has generated a fascinating hypothesis of mine, which is >"The Chess Analysis Project will reinvent all the great chess openings by post >processing." If it does not come up with "normal" variations, it indicates that the computer assessment differs greatly from the human assessment. Given that the human assessment is based on a ton of experience, if a clear tactical bust isn't present, human experience is more likely to be correct than the machine analysis. You can use these differing positions to tune your position evaluation. >And a corollary: >"The Chess Analysis Project will invent new openings superior to any in >existance." Hmm, possibly new variations. Entire new openings would be surprising. Anyway, if they are "superior to any in existance", they will immediately become obsolete, because people playing the other colour will avoid them. ;) Dave
