Yes... But we are not talking about _weak_ programs.  We are talking about
reasonable programs..

Not from my perspective.  I specifically said pick a 1997 program, but we
will run it on some sort of super-hardware that lets it run at 200M nodes per
second.  Play that against _any_ current program on current hardware and the
1997 program + magic hardware will win every match.

I don't believe there is _any_ way to compensate for that much speed, unless
the faster program is horribly written.  Which doesn't fit with either deep
blue nor any 1997 micro program.
