IF DF draws all games as black, and loses all games as white, I wouldn't _begin_
to say that is a GM performance.  Rather, I would say it was just good match
strategy by the GM to not try to overcome the disadvantage of moving second in
those games.

The only useful information will be learned dependiong on which of the following
happens:

1.  Hubner wins handily.  Fritz is "suspect".

2.  Hubner wins.  Hubner is better than fritz.  Could be several hundred
rating points better, since the draws could be strategy for winning the match
at the cost of .5 points here and there.

3.  Fritz barely wins.  Fritz is very likely a GM-level player.  Not
necessarily anywhere near Hubner's rating, but still probably a GM, unless
we all see something very ugly going on.

4.  Fritz wins easily.  Then it really must be a GM of some sort.

I don't know enough about his computer skills to make a comment there.  But if
the games are really 40/2hrs, with a secondary time control as well, then if
he loses, it will make a big point IMHO.  If it is just game in 2 hours, then
things might be interpreted differently depending on how the human loses.  IE
ahead in the game, but blunders in the last few minutes of time scramble..

I would agree.

I'm not backing off a bit.  I am simply saying that _if_ the human wins, it
doesn't matter whether he wins 6-0 or 3.5-2.5, since it is possible he could
win 6 0 but he chose to take the 'safe road' with black whenever possible.

IE if Hubner wins, he is better.  How much better can _not_ be determined by
the final match score.  Which is why matches generally are not rated.  IE if
I win the first game, I will try _very_ hard to draw the remainder and win the
match, even if I could win every game most likely.  Because trying to win can
clutch defeat from the jaws of victory, which is foolish in match play.

"crushing" is a relative term.  Quite often it means locking the position up
and waiting for your opponent to make a mistake.  One cute strategy is to give
a pawn to the computer and lock things up.  It will totally wreck its position
trying to hang on to that one pawn advantage without drawing.
