And if your wise analyse some of these positions (from the point when the programs get out of book). Chessbase once delivered an openings book wich was ment to be fore computer computer games I believe on chessbase magazine 62 if not 64 Though I doubt this book will be fine to day against programs with good openingsbooks it has somelines in it which can be a weapon against oponents with a small openings book. If you want to put analysis in your book 80 ply's and above are advisable Sometimes the move which won the game and was not found by computers might be on move 40 or later by moving less moves from this analysis in your book will leave it with the position it will draw. (So this is the way if you want to build a real qualety book) An other way of being sure if you want to put in less moves is see how you program does from out of book against other engines Which does not show if the openings line is corect or not but on how your program handles that openings line. (You could save the games your program played and won with that openingsbook and after having played many games create an openingsbook with the database of these saved games. You will get an openings book of position your program likes. Then there still is the project of aproved (Checked with programs using much time a move) of 2600 rated games on Dan Corbit's site But most of this was all mentioned 1 week ago in the threat (un)authorized openingsbooks.
