And you do?  :-)

Of course. That is obvious and I never said otherwise. All I said was that black
is OK if he plays cxd4 instead of Rc7.

I agreed this is not the type of position a human wants to be in in another
post. Did you read it before you shot off your mouth?

>Therefore Adams Rc7 is a completely understandable decision.

I agree that Adams decision was understandable. I never said otherwise. It was
also a mistake, that's all; an understandable mistake. I have always agreed that
by this point Adams was in the type of position that is hard for a human to
play. That does not mean he made mistakes earlier. It is easier for white to
create open, messy positions that are hard for a human to play than it is for
black to prevent it, so just because it happens does not mean Adams made
mistakes prior to getting into such a position. Hyrda won because Hydra played
well, not because Adams "blundered" or made "outright stupid" choices or "GM
Adams missed this move". I think it is disrespectful to GM Adams when people say
such things, especially since Adams _didn't_ blunder.
