with no book, it has been stated many times here that one must take the square
root of pi, divided by x(a-c2)-3x(a2)over 3.1285. Once this value is applied to
your results you will see that Rybka has an Elo of 2875 and leads your Fritz 8
by 22 games. Of course Uri will adjust this just a little when playing two
programs, one with book and one without.
