With a small but long-term advantage. Look into the different comments. If you
can't find it I will have a look. But Kasparov chose a different line. BTW the
better line was already mentioned on the Fritz server. Ok, Peter, if you want,
you can also claim that a comp could defend with - say - bad bishop against good
one or whatever. Against a comp that isn't won yet. But talking about super-GM
...

I think that your short message claimed something very modern today. Also Amir
has adopted that logic. He has a 3-3 against whom? Well against the best human
SUPER-GM. So, Amir is correct, DJ is also a SUPER-GM.

So, if we have weak Bishop against strong Bishop, and a comp holds a draw with
the weak B, then we can conclude that our concept of weak/strong B is nonsense.
We would never doubt that the human player did something wrong or was less
motivated...
