I understand that -- but my mainpoint was that EGTBs help in the same position and *do* announce mate. Unless Fruit can "auto-disable" its permanent NullMove Pruning in such a situation than it benefits from EGTBs. My mistake was to not post the rest of the analysis where the shuffling of pieces (as in my later examples) took place. Of course, if the shuffling and pointless moves did not occur than I would agree that the only loss without EGTBs would be the mate announced and polished PV (in the examples provided.)
