Hello Dirk,

sorry but you set wrong preferences in your first point! Fritz was
playing with special, non-commerical Power-Books, provided by ChessBase
especially for this tournament to the operator! So you can't compare
them to the normal Power-Books.

In your second point you may be right. These comments were taken in a
very short analysis when getting the game into ChessBase for the
bulletin. Some of my comments are a little bit ironic ("Killer-Books")
and shouldn't be taken as "gods words". For me and for Fritz 5 9...e6
seemed to be the fault. The black squares c5, d6, e7 are weak and
therefore the black king will not come to castle!?
But as I said, this was a very short and superficial analysis.

The fast machine of M-Chess was brought by Klaus Fuhrwerk, the organizer
of this tournament. He bought it only a few days before the first round.
M-Chess was doing 35.000 - 45.000 positions per second in the middlegame
on it!
