This is based on my personal experience with Shredder on >playchess.com and on about 15,000 fast blitz games. So, I am not making a >hyperbole and am claiming that a book just might be worth about 250 elo points. > >Djordje Sounds reasonable to me, but it's would be nice to back it up with a little experiment. So far, though my intuition tells me a good book can be 100 elo, I haven't seen a test match to support it. It'd be nice to have such experiment. First we need to define what we want to compare. For example: Fritz x with own book (and no learning?) vs Fritx x without any book or learning, removing duplicate games, up to 100 different games. Or maybe a better test would be vs Fritz x with a random and small book? José C.
