I don't think so. The Athlon can clear 200M in a split second, and
it plays 1 0 games fine with this setting.

Mm. Perhaps. Gandalf doesn't search very deeply, Tiger does. This won't
change when playing slower games. Gandalf will search a ply deeper, but
so will Tiger (and perhaps two).

There's no practical advantage to using 6 man
tablebases. (according to Robert)

>Sample size too small?

24 games isn't much, but it's still a huge score difference,
enough to be significant. I'll plug the result into elostat
and see what comes out.

I think it's fair comparison, the hardware was about equal and both were playing
at full strength. If there is something wrong with my setup
(I was operating Gandalf), then I honestly wouldn't know what is was.

Hmm. I'm disappointed with Gandalf so far. I used to run Fritz 7 on the same
account and with Gandalf the rating has dropped about 70-100 points!

It doesn't seem to be a real top program to me. I wonder what the SSDF result
will be.
