[2handed]

I think three betting after you get checkraised on that board is a giving to much action with a non-nut hand here. Check-raises on a paired board with no low out, even when they come from a bad player indicates a full house, one that more often than not has you beat (AQxy). My thinking here is simply that an opponent who overvalues the second nut full house probably also overvalues QQQ on the flop and will put in a third bet there. HIs checkraising of the turn also does not fit so well with that holding. Just call first raise on the turn; getting 4bet here and forcing MP out are not good things for your hand once UTG has checkraised.
