Against a typical player, you're going to get shown 44 or 33 here a VERY high percentage of the time. he will have QQ some of the time and chosen not to have 3-bet preflop, but I think that is probably not a large part of his range. While I don't think you can completely rule out AQ (somewhat logical) or 56 (very remote), I think the two lower sets are in his hand > 80% of the time. He almost hung out a sign for you when he called the 3-bet on the flop and then raised the turn.

Assuming you're unknown to him as well, he has to put you on aces or kings (or something similar) because of the LRR, so he will stop raising with AQ and either call down or fold. without a read, 56 gets a very small portion of his range. very few typical players will go for three bets pre-flop with any hand that will make two pair with this board, which leaves overpairs, QQ, 44, and 33.

we give KK about the same likelihood as QQ due to the lack of a preflop 3-bet.

As I said before, I'd lay odds on 33 or 44.
