I don't believe he lost on purpose with a sacrifice that could havw won against
every human and could have been the game of the year.

In the last two games with a won position for Fritz in game 7 and a better for
Kramnik in the last it is obvious that there was some kind of "gentleman"
agreement to make the match a draw. Meaning they screwed the sponsors, so the
next time they must go elsewhere for the money.
