Hi Pavel !!

Correct I posted it in one thread or another.

........but from your nun1 tests it seems that crafty is playing

This was the case at 1/0 at 3/0, 5/0, 10/0 seems it scores less.
Though also scoring better at 25/0.

True but there is no way to tell if the cpu is being utilized equally by
both Fritz and Crafty. Only way I think is two computers, I'll do it
manually if I have to, though not too keen on the 1/0 or 2/0 LOL.

No, I still believe other programs are equally hurt by ponder=off but maybe
Crafty has better cpu utilization or something....just a theory.
