I think the book hurts F5 more than helps. It's not tuned. And in any case, having a book and a learner is not so terribly unfair, isn't it. They all have them. >The 3 times speed give Fritz the 60 ELO points ahead ! Nonsense. F5 played matches on P200MMX vs. P200MMX and also on P200MMX vs. P90s, just like Rebel 9, Mchess 7, Nimzo98... Same method for all. It's the average what counts. >I guess this will decrease when the others were tested on FAIR machines. >Than the results with get a tendency into 50% and if the others cook or >make their learn-algos better, suddenly anything is possible again. > > >The big ahead-advantage of fritz is not real.

As I said before, this 55 points lead took me by surprise too. I expected Fritz 5 to be more or less even with Nimzo98, Rebel 9 and Hiarcs 6. But then, SSDF played twice as many games than I did. And I absolutely trust them. My point is not only the strength of Fritz 5 but the criticism about SSDF procedures when they have been a constant over the years, not a variable. Enrique
