Of course.
I know that gandalf earns more nodes speed from fast hardware.

I guess that for Gandalf 933 MHz is at least 3 times faster than your 500 Mhz
when for other programs it is less than twice faster.

I do not have 933Mhz and 500Mhz machines but my guess is based on the fact that
I used gandalf in PIII 800 Mhz(windows2000) and pIII450Mhz (windows98) and I
fooud that gandalf was more than twice faster on the PIII 800.

Gandalf likes the pentium and I read that the k6-2 450 that the ssdf is using is
even slower than the pentium for gandalf.

Gandalf is also slower under chessbase.
The problem is mainly in blitz and I see small number of nodes per second and
only after some time the number of nodes per second is increasing.

>b) or that his indifferent style againts human make it good againts computers?

Gandalf has a symmetric evaluation and it is not the best idea against humans.
It does not try to get open postions with tactics.

>c) or that they are running a far better version that my G version?

They are running a different version than your g version.

I hope that I have an answer.
