I have studied quite a few GM-annotated GM games.

A top program simply can not play in such a position 9...cxb5.
It was _not_ an option.

Btw, I guess it was a book move since it is in the Fritz8.ctg opening book
(might be wrong).

I don't understand in the first place why you constantly insist on that I fail

This position was an exception,not a common position at all.
