The short answer why I don't do as you suggest is that it will not give a very good book. Some problems: 1) GM games are far from flawless. 2) There is more to opening theory than what has been played or published. A book like yours will play variations that are just bad and that my engine opponents know how to beat. 3) Engines don't play one of the colors very well in some kind of positions (positions that GMs can play well). You would want to avoid these variations. 4) Compared to known and published opening theory, there are many, many new and equally good moves deep in the different variations, moves that your engine opponents will find and prepare. Hence, you would want to prepare your book more thoroughly than just "published theory" in whatever variations you play, so that you are not outprepared by the opponent's homework. So instead of your suggested approach, I manually tune and expand my book. This does not give me a shallow book, on the contrary, I often play games where I do not leave book until 10 or more moves out of "known" opening theory. In a sense, engine book cookers are opening researchers. That research can easily improve on known theory, and hence the benefit of doing it this way. Regards, Dagh Nielsen
