But are you smart and savvy enough to discern who the threats are and be prepared to face the right opponents? It seems obvious when you've got just one group of PCs, but how does the NPC sort through all the potential threats to find the real ones? That's part of his supra-genius.
Yes, smart and savvy opponents I can do. I'm mildly smartish.
Supra-geniuses? Not so much. I'm not a genius, let alone a supra-genius. If I was either, I'd be a lot richer than I am!
Having defenses based on your knowledge or your opponents capabilities? That's just "barely not being an utter idiot" tactics. That's not supra-genius tactics.
