It *is* very good to outsearch the competition nearly a ply, other things equal.
I don't know why you do not appreciate that. You think it's easy to get there?

Now you are still doing it! I explained why you calculation is worthless. Going
from 70 to 100 doesn't make it less worthless.

I would expect Crafty at 2x speed and Fritz to be pretty close, and at 4x speed
Crafty would win.

Well, I can't remember to have said this. Just that any of them can whack Tiger,
if set on faster hardware.

What theory? Ok, at FICS I have seen slow Crafties with a 2150 rating and fast
Crafties with a 2450 or even higher rating. Remember that FICS ratings are less
"inflated" than ICC. If you make Crafty slow enough, it's rating COLLAPSES.

Best regards,
Bas.
