You didn't - this is some of the "added extra" I put in to keep the discussion moving. I have studied the analyses of GK v DB '97 by 2 GMs - Daniel King and Yasser Sierewan. They both had Gary winning in game 1 (which he converted), and games 3, 4, and 5 (which he failed to convert). >>* DB achieved the advantage in 2 of the games > >It only achieved an advantage in the last game as a result of the opening. Yes - that's right. But having obtained the advantage, it converted it. >>* GK converted 1 game in which he had the advantage > >This is correct. > >> >>* DB converted both the games in which it had the advantage > >I would be fascinated to hear about this advantage it converted in the second >game. It obtained the advantage courtesy of its opening book in game 6. It converted it into a win. >>From this, I draw a conclusion (in computer chess, if one wishes to draw >>conclusions, one often has to base them on flimsy evidence). > >If the evidence is flimsy, so are the conclusions drawn from it.

If the above conclusion is wrong, by all means say so - and why! >>Albert also stated that he is able to beat all the chess programs he possesses - >>which I think includes the new Rebel Tiger. > >Rebel Tiger? Don't have it. That's a shame. Rebel Tiger should now be available for purchase, and currently has an SSDF rating of 2696. Which of your programs is highest on the SSDF list, and what's its SSDF rating, please? >>However, it's not good enough to beat them in the comfort of one's home. > >Really?

But it has been statistically demonstrated that "self administered" IQ tests tend to score more highly than "overseen" IQ tests! Can't think why... :) >>If he >>played them under competitive conditions, some extra considerations would come >>into play: >> >>* Some of the evaluation factors would be changed, so that he may not be able to >>predict their moves so accurately > >Predict? I honestly don't understand what you mean by this. I am suggesting that if you play your computer a lot, you'll learn to predict what moves it's going to make. >>* The whole thing, from opening books to evaluation factors could be tuned to >>produce an optimum game against HIM. >> >>This is the reality that GK faced against DB in May '97. > >What is your point?

OK - is there any way that you can get to play Rebel Tiger on the same level of equipment that the SSDF used? >> >>If anti-computer chess is alive and well, why did IM Dan Hergot lose to Hiarcs >>in early '97 - to what is now an old version of Hiarcs on old hardware? > >He didn't play anti-computer chess. > >> >>And why did GM Ruslan Scherbakov lose to Rebel Century? >> > >He didn't play anti-computer chess either.

Is there anyone from the SSDF following this thread? Can you tell us when the last time the ratings scale was checked for correlation with the FIDE rating scale, please? Thanks. Graham. >> >>-g
