This is completely wrong - you need to understand the ELO rating system before
you make these kinds of statements.  Even at a 400 point rating differential,
the lower rated player has a win expectancy of .091, meaning that a mere 2370
player could expect to draw 2 games out of 10 against Anand.

  The

Indeed 1/100 would be slim, but as I explained above, the odds are *much* better
than this...

  What's even more amazing is that Just as Bertil Eklund

I'm not 100% certain that Rebel *isn't* playing at GM strength.  Frankly, I
think there still haven't been enough games to know for certain.  Akopian's
opinion is one I would value highly, but in the end, the only evidence that
really matters is how Rebel performs in 40/2 games against strong humans.  So
far it has achieved a performance rating of 2485, and that isn't quite GM
strength.  (And certainly not high enough to earn a GM norm)

Sure, fine - that's Bob's opinion.  By the way, I think Bob tends to quote these
numbers as USCF ratings, so you'd need to deduct ~75 points to translate that to
a FIDE rating.  Again, I don't care about people's opinions.  We have lots of
real results now, so lets focus on them.

  Though strangely, even though, We have 1 gigahertz machines

Maybe.  The difference seems to be that you are willing to accept this on faith,
while I'd like to see more evidence...

You have this tendency to throw around "facts" rather loosely (see the 1/100
silliness above).  Can you please post a list of the IMs that he has played
recently?  If you can't post it, then please stop making this argument.  My
guess is you'll only be able to find a very tiny sample of games, in which case
the result is particularly meaningful.

Wrong again - my comment was that it was "basically a non-issue" against
GM-strength players.

We will have to agree to disagree on this one, because it's purely a matter of
opinion.  My position is that the "contempt" problem you described above is no
different than a dozen other quirks of chess computers.  You might as well be
arguing that they aren't good at long-range positional planning.  A computer is
what it is.
