I'm sure that is over-estimated a lot (except for killer variants, but those are very few, and I don't even think most books have any, and book learning limits their chances). For example, If you could play 1000 games Fritz+Fritz book vs. Shredder+Necchi book, and then 1000 games Fritz+Necchi book vs. Shredder+Fritz book, I doubt that a "statistically significant" difference would occur. (A theoretical example, because AFAIK you can't convert the Necchi book to CTG.) >(...) Are there any recommendations as to which is the best opening >book for universal use in a tournament? I'm not sure if it's the best option, but it can provide much more variety than common sets of opening positions: The small "Kurzbuch" was generated for the Fritz GUI from a larger database of (human) master games. The book is exactly 3 moves deep for each variation. I slightly editied it to achieve a bit more variety, i.e. less often sicilian after 1.e4. http://members.surfeu.at/mscheidl/Kurzbuch.zip It certainly doesn't favour any engine, with the possible - theoretical -exception of engines which are especially prepared for the early opening. (I always thought, since years ago, Rebel has a special talent for that, but that can't be tested in the Fritz GUI). Sometimes you'll see that the engines follow known theory, more often they will create new and unusual continuations. Advantage: Engines will create (IOW "shape") their own middelgame, don't go into endgame right from the book's end. Disadvantage: Games will probably (most often) be useless for the opening studies of a human player. Regards, M.Scheidl
