It was quite simple actually, Celes just had a plus when out of book, fritz
decided to draw 8 times while that build of Celes didn't comprehend 3fold
repetition yet. I admit the result is rather excessive, but it does point out
the problem. Would you rather start with -1, -2 or worse out of book or with
-0.5..0.5? Note that good books also give you solid positions with few
positional weaknesses.
