Gentlemen,

It seems that my memory did err slightly. It was indeed van der Weil and not van
Wely, that Rebel defeated. Nonetheless, here are the facts:

Rebel defeated Yusupov
Rebel defeated Anand - by the way, Rebel played on a standard PC of 1998, no
special hardware
Rebel defeated van der Wiel, a GM having success defeating other engines
Rebel drew with van Wely.

Since Fritz and Junior played with special multiple processors, with each
processor being faster than the single 1998-vintage PC that Rebel had when
defeating Anand, then I think that Rebel's success is all the more amazing.
Sure, some of the Anand match was played with short-time controls. But I suspect
that if Rebel had the chances that Fritz and Junior were given (special hardware
and special opening books, etc.) then I'd still put my money on Rebel.

I respect that you disagree with me. So what? There's no need to make the
disagreement so personal.
