I believe Fritz 7b running on a fast PC can indeed win *some* 40/2 games against
Kasparov, unless Kasparov always plays for a draw.  I believe Kasparov would win
a lot more games than Fritz would, if the match were of any significant length.

My estimates were around 2550, which is halfway between your 2350 number and the
2750 some claim.

But it's not my estimates that matter, it's the concept of uncertainty.  IMHO,
nobody can be really certain of the true strength of these machines yet.  Only
when GMs have spent a few years with them as frequent opponents can we start to
know the computers' real strength.

I think most GMs over 30 or 35 may already be too old to "re-wire" their neurons
to the different approaches required (e.g., avoiding all possible tactical
inaccuracies at all costs, even if it means forgoing certain promising
strategies) against computers as opposed to the approaches they've spent years
and years refining against humans.
