That I can't answer.  But the rule saying it can't be done is just bad, period.
IE I have
some global sort of evaluation terms that I could (and would) modify between
rounds.  If
I noticed the human trying to lock up the pawns, I'd turn that scoring term up a
bit to try to
avoid it.  If he tries to attack then I'd turn that up to push him another
way...

Fritz is playing fine, for a computer.  Unfortunately, it _needs_ to be playing
like a GM,
which it is not doing at the moment...

Kramnik's match agreement highlights this problem with all the practice he has
had against
an opponent that he _knows_ can't change ideas between rounds...
