I was talking about anti-computer more than anything else.  His first four
openings were
tame and nearly perfect for playing against a computer.  Then he got more
aggressive and
left his original plan, it seems...

My point was that in the Kasparov vs Deep Blue match, Kasparov resigned in a
game
that he thought was lost.  But which deep analysis showed was drawn.  Kramnik
resigned
a game that was probably drawn, although it has not been subjected to the same
analysis as
the DB/GK game.  But the similarity is there, he resigned _too early_.

In the last game Kasparov made what most considered to be a blunder with h6.
Kramnik
_clearly_ blundered a piece and turned a probable draw into a sure loss with one
move that
takes most programs a few milliseconds to spot as losing.

Yet Kasparov was routinely criticized as playing like a 2000 player, yet Kramnik
has not
gotten any such comments.

Everything is the _same_ except for the opponents.  One was the hated Deep Blue
from IBM,
the other is a popular micro program...  :)

I concsider that to be a strategic blunder, if not a tactical blunder.  But that
only
highlights the issue here.  Kramnik actually played much worse overall than
Kasparov
did, but was still able to draw the match.  I think the first four games were
more revealing
to me, personally.  The last 4 games seemed to be twilight-zone stuff...

I certainly agree.  Kramnik made more bad moves than Kasparov, yet he didn't
lose
the match. That says something...
