  Ok I don't know exactly how Larry kaufman calculated the 65 pts difference
going from 30 0 to 40\2, , but I see no reason to doubt him, his reputation is
impecabble, and he is both a programmer and a very strong chess player. What it
boils down to is no one can really say for sure how much of a difference it is
going from 60 0  to 40/2 but I know one thing for sure it is not the 300 pts
that Robert Hyatt is projecting, common sense shows me that much. I think 65-100
pts is more reasonable, this is ofcourse a guess, but my guess is as good as
anyoneelse's .
