I am talking about "black is better after Nxg4 than after another move."  IE the
score goes _up_ for taking the pawn.

Eh?  So I can play _good_ and still get a bad position?  :)

Then I have been playing "good" since I started playing chess at age 7.  :)

Yeah, but do you think it played "the rest of the game like 2900"???

I don't.  Again, games 1 2 and 3 could have been all losses, easily, and should
have
ended 2.5-.5 at least.  That's "super-GM" level chess?  Particularly after
looking at
game 1?

Another criteria for super-GM chess (IMHO):  In which game did the comp have any
sort
of initiative out of the opening?  Perhaps in game 5 after the sac, and even
that is not a clear
good move as most seem to think it loses.  If you look at the 1997 match, DB2
played clearly
strong chess and had an initiative in several of the games.  Game 2 comes to
mind as a game
with only one flaw, that of Kasparov resigning when he should not have.  But
Kasparov was
defending the entire game.  In which game in _this_ match do you see that
happening?  And I
don't particularly assess DB2 as "super-GM" stuff myself.  Very strong.  Very
consistent.  Just
like Deep Junior.

But I tend to play down the hyperbole.
