Hello Tord,

nice experiment.  However, I'd like to add that Vincent was actually making a
hyperbole (a way of emphasizing what you are saying by describing it as far more
extreme than it really is.... as the definition goes, of course), and did not
actually mean it literally.

You took him literally, probably tongue in cheek.  I will now seriously claim
that a good book COULD be worth anywhere from 100 points (conservative
guesstimate) to 250 points (very liberal guesstimate).  The range depends
entirely on the type of position that ensues and the time controls.  In very
fast games (G/3, G/5) I claim that the worth of a book is even higher because
the engine you are running is as good as done in after coming out of book with
an inferior position.  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.
