If you do use the Fritz database to create an opening book, it's best to
restrict the games where both players are above a certain ELO rating, such as
2400 (a sensible value IMHO).

First create a new database. Then filter the games in the Fritz database for
both players above ELO 2400. Then copy the resulting games into the new
database. Import the new database into an opening book. Personally, I think the
best result is reached by choosing an absolute ply depth of 60. (Chessbase
recommends a relative ply depth of ECO + 30). I'm open to suggestions.
