That's actually a slightly different topic. I was NOT actually referring to humans learning the weaknesses of a *specific* program, but rather to the likelihood that most GMs will improve their overall anti-computer abilities with time, and SOME of them will improve this ability a LOT. Take a strong program running on a fast PC -- I'll agree with you that it could get a 'rating' of 2700 in current GM matches -- and put the only copy of it in a vault for 6 years. Let no human play it or study it during that time. Let the best 3 anti-computer GMs of the year 2008 play matches against it. I think there's a very significant probability that that SAME program running on that SAME hardware would then achieve a rating of 2500. Did it get 200 points weaker sitting in the vault? I contend that the reason computers IN GENERAL have done as well as they have against GMs in the past 2 years is that GMs have in general not learned a necessary skill -- one that is SEPARATE from traditional chess skill -- that is required ALONG WITH their chess skill in order to play computers. The reason GMs have not learned this skill is simply that it has not been required until very recently, whereas standard chess skills HAVE been required for centuries in order to defeat humans. Interestingly, GMs have developed a whole set of psychological skills that ARE required to do well against other human GMs but would NOT be required to do well against computers. In conclusion, there are at least 3 separate skills involved: To score well against humans, GMs need good chess skills AND good inter-human psychological skills but NOT good anti-computer skills. To score well against computers, GMs need good chess skills AND good anti-computer skills but NOT good inter-human psychological skills. GMs _all_ have good chess skills and good inter-human psychological skills. Most GMs do NOT YET have good anti-computer skills. > >> >> >>Please choose one!
