Sick river spot with 3rd nuts versus Vanilla TAG

[FoldEqu1ty]

Villain is 20/10/1, and plays a very straightforward ABC game. He often plays pot control with TPTK, doesn't fire many big bluffs, and passes on most thin value bet spots. Running into AK or AA here would be disgustingly sick, given pot odds and the combinations that my KK wipes out - but for the life of me no other hand makes even a shred of sense. I strongly suspect that he flat calls that river with 33, and do not see him firing a big bluff.

I hardly *ever* make big folds, but I really don't know about this spot.
