 " In the 2 slow games Anand didn’t show any overwhelming
superiority, as he would have against a 2400 player. I have no doubt about Anand
being stronger than Rebel 10, but not by 400 Elo points. During 1997 and 1998,
Anand drew 48 games playing white. The lowest ranked opponent in these games was
Ljubojevic with 2565. Then Piket with 2575 and Hübner with 2580. All others were
rated 2630 or higher. Of course, all well known GMs. I don’t say this as proof
of Rebel 10 being a GM, but overall as strong indications that its real strength
is well above 2500." (Enrique Irazoqui)

It is best not to (simply) attempt to stick with ones oppinions but rather to
follow the very important concept called "the weight of the evidence".   Based
on two games against Anand the weight of the evidence is not overwhelmingly
heavy in either direction.  However, from these games one would be hard pressed
to form a hypothesis that "the likelyhood is Rebel10 is not GM strength".
Indeed the evidence would lend to one forming the exact opposite hypothesis.


 But I'd still bet on Anand, after giving him
>a few games to see how it plays....

As i look in this post i see no hint or even dream of a suggestion that Anand is
not clearly superior to Rebel10.  In fact if it isn't as strong as a kaidanov or
Gulko as mentioned previous i think Anand bieng stronger can be taken for
granted.

I see no mention of anything other than 40/2 games in this post.  Also in other
post in this thread even more 40/2 game performances are attested to by other
CCC members

Why are you talking about how they are doing at faster controls there is even
more evidence that they are GM's at this speed, Anand was trashed in the fast
games, and the above game you mentioned by the IM in all likelyhood was but
another one of these quick games.  As for crafty playing an IM at  long games,
Crafty i'm sure is a competent opponent (the latest crafty anyway (it's stronger
IMHO).  I saw crafty 14.? lose a match 6 0 at 40/2 against chessmaster).
However Crafty isn't in the same league as Rebel10 or Ftitz5.
