Bob, Those 10+ years ended in 1993 or so, the last time that Deep Thought played and won against a micro. As you well know, post-1993 versions of Deep Blue played very few games against micros and won none of them. In 1993 the top micros were rated about 2300 (according to SSDF, the top four are rated 2322, 2302, 2292, 2288), so dominating them doesn't prove superiority over today's top programs. What's more, if yout play over old DT/DB games, it seems to get into serious trouble in every other game it plays, but gets away with it. There was a game it played as white against Zarkov in ACM (1992, I think), which it made every attempt to lose, but Zarkov apparently didn't want to win. Playing over this game, you realize it is lost not only against the top programs of today, but even against the middle of the pack. I also wonder how many of today's top programs would fail to exploit DB-Prototype's bad opening against Star Socrates. I think as late as 1995 (DB Prototype, Hong-Kong), DT/DB had such serious flaws in its evaluation and search (as Fritz showed), that I seriously doubt it could equal today's top programs. About the later two DB versions that played Kasparov, they were obviously stronger, but never played a single game against a micro. Amir
