I think checks in the q-search is an exaggerated advantage.  I play all of
the above programs on ICC, all the time, and I am not getting rolled into a
ball by any of them.n  Didn't you play a bunch of games vs crafty using a
quad 550 xeon for Diep?  Did those q-search checks make a big difference?

I don't think it is a bad opening.  I generally don't play the Sicilian as
black against computers.  As white, I alternate between d4 and e4 openings
so black will get a chance to play Sicilians.  At a reasonable time control,
my quad will find nxe6.  My PII/400 notebook fails low at 5 minutes.  The
xeon would probably fail low at the 1-1.5 min mark.  It would then use as
much time as needed and would certainly find Nxe6.  I am surprised that the
alpha didn't have time to find this, or at least have time to fail low at
depth-14, which is strange.
