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! Karsten
