I played so far 60 games with Fritz 5 at 40 in 2 against the programs
you mention. Fritz 5 scored exactly 50%. The margin of error after 60
games is very big.

I gave Fritz 5 no advantages at all. It did play with 100 MB hashtables.
All the DOS programs played with the maximum amount of hashtables they
allow, between 60 and 63 MB. The exception was Nimzo98. In this case,
both, Nimzo98 and Fritz 5 played with 48 MB hashtables because I have
only one machine with more than 64 MB RAM. All on P200MMX.

I did use the Powerbook. The idea was, and still is, to play all
programs at their very best. No advantages to any program in particular.

Ossie, this is getting boringly repetitive. It is you who has to provide
proof about the commercial Fritz 5 playing differently than the
autoplayer version used by SSDF and by me. As I told you a dozen times,
it is easy to check this out. I checked it in some games: same move,
same eval, same depth, same time. You refuse to provide proof. All the
rest is sheer speculation. So much for that.
