The program could internally use asymmetric evaluation, for instance open files
good for me but bad for you.
But do you want your Fritz to open a file against Junior at any cost and get
slaughtered?

Of course not, so this evaluation should _only_ apply if the opponent is 200 Elo
or more weaker, or if he is human?
What if Junior is underrated by 200 points because it is a new account?
What if the human is Garry and the program is really the underdog?
What if your opponent is not rated?

It opens op a whole new bag of nasty problems.
