IE I use the servers to test the code (you will notice that Crafty _never_ crashes or hangs in WMCCC events, it just plays chess) and I occasionally see things that are a "trend". But I pay the most attention to long games against GMs (yes, it plays them. You might see it playing a guest at times and be suspicious if you want. :) ) > >If it is tuned to play against GM's, I would love to see some matches like the >one's Rebel, Junior, Fritz have done recently. > >Again, I think Crafty is a good program.

You can tune to win fast games, and you can tune to win slow games. It is _very_ hard to tune to win both, with a computer. If you ask computer operators on ICC, you will find out who thinks they are better than Crafty at 3 0, and who thinks they are better at 30 30. The answer will be pretty revealing, as most operators have figured out where they do best vs most all programs. For short games, you use knowledge, scaled pretty high, to offset a lack of depth. At long games, you can't over-compensate like that or you get shredded (hint: at the 1997 WMCCC crafty was at an all-time high on ICC, killing every GM that came along. It played horribly at the WMCCC event. Further study showed that at longer time controls it was dying... Blitz and standard are two completely different games. And chess vs a computer vs chess vs a GM are also two completely different games. > >Just a question, no hidden meaning here at all. > >Best Regards, >Chris Carson
