Wow. I own both Shredder 7, and Shredder 8, and the default books that come with
the CB interface were horrible. Even with the tournament setting off, it was to
wide, and was honestly just horrible.

Shredder 7 and 8 both gained an immense amount of opening strength by using the
Deep Fritz book, which was the standard practice on the servers.

high. A good book can easily bring more than 10-15 elo points to a chess engine.
