i bet and probably fold to a raise. there is little chance he would bluff in this situation, and even less he could have a bluffing hand. and since none of the hands you beat would think about c/r the river after that turn card and his comment, i fold to a significant raise.

I understand this line of thinking but disagree. I would definitely bet the river but i would never fold to a raise. As a matter of fact, i would overbet the river to the point where you are pot commited. You might even want to move in (especially against a opponent who has trouble laying down hands). If your opponent has a full house he will probably call. There are rare exceptions against ultra conservative players, but here is why you must not fold here very often:
1. You have the second nuts!
2. YOur opponent might have misread you here and may try to take you off a hand like aces, or AK. Granted, this won't happen often, but it does happen.
3. It is much more likely (statistically) that he has one of the other sets
4. If you are not willing to lose your stack with this hand, it should not be on the table.
5. Opponents will call in this game with other full houses.
6. you have the second nuts!
