44.

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.

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.

Could be. 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.
