I don't know if 3-betting with this hand was the play. Even calling is questionable, unless you anticipate a lot of people that you can outplay. Trouble is a lot more marginal flops will hit then you can miss.

From the flop on, you play was great, you had the odds to coldcall that in position. The turn was fine as well seeing you picked up an openender. The river is a must call. I know the UTG+1 most likly has you beat, but the pot is huge and you have the top pair. I am guessing he has a set, but you never know.
