No, the people who cares about opening books wants a reasonable selection also for restricted books and not only one move...that would be too boring... >I agree that you need a lot of work. > >One way that can only help the engine is simply to play a lot of games at 120/40 >for Shredder(after you already have a book) when shredder has significantly >faster hardware than the ssdf hardware and the opponent use the ssdf hardware >and simply record the wins in the book. well, it is not so easy and may not work...if a lower time is given on the opponent which may cannot use the opponent time to search further, it may come out with a different move...also there are learning features, so after one or more wins the opponent may select a move that changes the score completely! > >There is good chance that the opponent is going to play the same game in the >ssdf games and even if it does not play the same move some moves after it is out >of book you get time advantage and a good chance to win.
