CAN YOU PROVE THIS? Have you any hard or soft evidence that this is
indeed the case?

Any FACTS?

Did you know that the Fritz 5 Powerbook doesn't contain *ANY* learning
values?
Fritz even plays (and gets punished badly for doing so) the 1.c4 English
opening where it reliably loses. No book tuning at all - all the other
top programs rely on hand tuned, computer optimized opening books. Just
a few FACTS about 'unfair advantages'.

Sorry, I don't want to start the debate all over again - it serves no
real purpose. My point is just that

a) we don't know if the other programs got less than 64 MB RAM (this
might have been different for individual matches, for all we know, e.g.
Nimzo getting 200 MB hash tables vs. Fritz with 44 MB HT - but the point
is: we just don't know)

b) accusing F5 of book tuning of any kind is most ridiculous when you
consider that it uses a big GM database without any learning values or
any other optimizations. It exclusively relies on aggressive book
learning to save the day.
