The proof is obvious. 8 bad games. Of course Fritz was even
worse in a few games than Kramnik's play. That's obvious.

It is not so hard to see the level to be low. See which openings
lines were played. No 'world class' openings. Qf6 in the scotch even :)

Bxf7 give away check. Amazingly still with unclear chances.

Qc4 give away check. Obviously with direct zero as a result.

8 bad games. The first few games he just played default moves. No 2800
level.

What is the CHANCE that he plays 8 bad games in a row?

I DO NOT HEAR YOU?

0.01% ?

0.000001%

0%

It is like kasparov-deepblue. Play for 2.5-2.5 and then kasparov played
such a horrible opening again as 'anything works against these dumb
machines'.

Obviously Kasparov made the mistake to lose that game. We can't proof
kasparov deliberately lost that 6th game. We can't proof he deliberatly
played beginners level game1, we can't proof he deliberately plays
like 6 very bad moves in game2 against the bad IBM machine which day
before that even lost a game where kasparov did except giving
away pieces to lose.

We can however say something statistically about the games.

Kasparov games - 1800 level in openings and 2000 level further but
                 of course not giving away direct pieces let's it look
                 like better usually. On average 5 mistakes a game
                 from both sides. That's really horrible.
Kramnik games  - very bad openings and default moves and 1 blunder
                 the mistakes from Fritz were bad, but not trivial to
                 identify to any level under national master level, except
                 when using positional better software.

Anyway, the pressure is on kasparov now. Because Kramnik has done something
great for his sponsor and opponent. 4-4. How is kasparov going to let
junior look like better now?
