I did read the entire thread, except the post you made about the same time as
me, and the talk has been about whether g5 was good or bad. Just read what you
wrote "and i'm surprised that you don't understand that it's not such a great
idea here..." (meaning the move g5 should have been avoided).

I think the talk should have been about Bc7 or like you also wrote h6, those
where more suspicious, IMPatzerO.

I don't think it is irrelevant, I don't see why Uri or me should trust some GM
analysis made on the fly, during a live TV transmission when GMs can't even get
it right in the analysis they publish in books.

General assessments are not very relevant when talking about a concrete example
such as this. I guess that is what you are saying also.

The g5 move was the one refered to as a "blunder" (read the thread please:).
I do agree some of the others look more suspicious :)

It makes a difference as to whether it is a blunder or not.
It may look ugly, but if it is forced by tactics then it's not a blunder per se.
