Hi Jouni,

Fruit doesn't like the Fritz 8 and Deep Fritz 8 books. When I used my own book
in a blitz match Fruit 2.2.1 against Deep Fritz 8, the score was around 75% for
Fruit. When both used the Deep Fritz 8 book, the score dropped to 55%. Both
matches were 100 games. Of course there is an error margin, but I see that the
Deep Fritz book plays a lot of lines that are not very suitable for chess
programs (King's Indian for example). So for me it is no surprise that using
book.bin gives much better results than using f.e. DF8.ctg.
