It's been awhile since I looked at the Fritz manual, but seems to me I saw something about learning. I vaguely recall that Fritz will modify it's opening book. If you set Fritz to use PowerBook as it's opening book, then it will modify PowerBook over time. I also vaguely recall that you have to enable the learning feature. I guess I could go and study the manual again . . . Bob D.
