The river is just a fold. No one is bluffing here. You are still uncapped and probably have a strong overpair. More than likely he just flatted KK or AA pre trying to keep the BB in who I assume is a fish for donking this flop.

You can make an argument for getting out cheaply and just folding flop. Even though villain reps close to nothing I think he just flats fds in this spot always probably and I find it unlikely he bluff raises this size? As played though, I think its pretty standard and the river is just a shrug/fold.
