Quite >accurate, in my opinion. An ICC rating can't have any relation to reality other than that the numbers are something over 2200. Lots of those games were with Crafty, I think, and Bob had it set to use only one processor, so that must have had some effect. Crafty is probably the wrong program to use if you want to see CST rack up a big score, because it is so paranoid about getting mated. CST plays funky stuff, which I like. I think that is a good thing, it makes for interesting chess against the humans, and sometimes makes computer opponents look stupid. The problem is that it's not like this aggressive style is an enhancement to the strength of the underlying engine, it seems that instead that there is a downside to this style, if the goal is to maximize points. Sometimes it can't win the positions it gets, it's like it tries to do one sacrifice too many or something. I think CST is a wonderful project but I don't buy arguments that it is only a little bit of fine tuning away from being champion. It seems to have a hard time competing with the rest of the crowd, but I give it credit for not being a part of the crowd. bruce
