Thorsten has stated here that he uses the book on CD. So there's no learning taking place at all. Also, the book learning concept naturally works best when a large number of games against preferrably strong opponents gets played. This is usually the case e.g. in autoplayer (no problem at SSDF) or server games (no problem e.g. for Mark Young). This is also the case when you play a "match" of e.g. 20 games against the same opponent. That's why autoplayer and server results are better than "amnesiac" results without any learning going on or learning from only a handful of previous games, some against opponents more than 200 ELO points weaker than Fritz. Remedy if you don't play many games but want to benefit from learning: Let Fritz learn e.g. from the public SSDF games (maybe only those where also the PowerBook was used). There you have several hundred games, add the games from Enriques tournament if you like and Fritz will probably benefit more from its book. I don't like the "de Gorter" book on CBM 63, BTW. I think the PowerBook is better against all kind of opposition. Moritz
