1000 times?  How did you get to this number?

Huh?  8 piece?  Any idea how many terabytes of disk this would require?  Not to
mention the months(years?) it would take to generate the tablebases.  We're just
now starting to see the first 6 piece tables, and I don't believe anybody has
ever generated a 7-piecer.  Maybe a TB expert will chime in and tell us what it
would take to get to 8.

What you're describing is a machine that would score ~99% against Kasparov.  I
think computer chess will *never* reach that level.

This goes back to the old debate about what ELO rating a computer would attain
if it played chess perfectly.  I have always argued that this number is finite,
because I believe that the drawing margin in chess is sufficiently large to
allow one side to make a few mistkes and still draw against a perfect opponent.

But that's a whole different discussion...  :-)

I think that more speed is not the answer, because at 15+ plies, you're already
faced with with seriously diminishing returns per extra ply.  Any tactics that
exist in the position (or that a human would ever have a prayer of finding) have
long since been discovered, so the computer's positional evaluation starts to
become the limiting factor.  And computer chess still has a long, long way to go
in that area.  As you've stated yourself in other threads, the GMs are getting
better at exploiting these weaknesses.
