I am not a Fritz-expert. Ask Moritz. He knows. All i can say is, that i checked
this again, and i had NO problems to reproduce the moves again, so I would say
something must have been influencing YOUR effort of reproducing my game.
I have, also on another machine, no problems to replay the game...

Mchess7 played a draw by repetition line at the championship in Paris against
Chess System Tal.
Mchess7 had white too.

It happens. I don't like big books too. Because of this reason.
I have never got an answer by marty's team WHY this line was in the book,
especially why mchess played another move than the original game that we found
in the database later...

It sounded different to me. You said the probability would be near sero. How can
this fit together ? Do you believe I forced the moves to bring fritz into a weak
position ?! :-)
As i said, i have checked this again. Anythig looks normal...
I remember ChessSystemTal with a book of 520 MegaByte played in a tournament
somewhere in germany an opening and was completely lost after leaving book.
WHY ? The result of the game was not accurate due to the weak play of the
human-players. CSTal followed the line, thinking it would win, suddenly the
computer-opponent corrected the weak line, cstal came out of book and was
killed.
