I think I know by now, why the Nunn position(s) has been used in this test and the reason is defendable. But in general I don't think it's a good idea to use them for testing purposes. A computer chess program is a package deal. If you purposely remove certain elements, ie. opening book or ponder, you get results that are purely of academic interest. I your're adament of making a direct engine to engine comparison _everything_ should be removed including EGTB (if you're real zealous a third party GUI should be used). And no starting position should be chosen, which includes Nunn. That's my opinion. Best wishes... Mogens Chr.
