All these games aristarch played with book learning off. Yace book learning was on but it was in "random" mode. Aristarch don't have any kind of "ini" files to setup it's options. The only way to setup the book learning (under CB GUI) is to load it up and edit it's properties. My mistake was that I assumed Aristarch book learning was on by default, it wasn't. :( I am not going to change it now. pavs
