20-40 Pocket Jacks hand

[Noo Yawk]

Pretty loose-aggressive 20-40 game.
UTG open raises. He likes to open raise pre-flop with anything, and only stays after the flop if he hits some sort of a hand or draw. A strong aggressive player who plays well post-flop 3 bets. I look down and see pocket jacks. Knowing that MP is trying to Isolate UTG, I go ahead and cap. UTG is going to cap anyway, and that means nothing.

The flop: A-5-6 rainbow.
Utg checks, mp checks, I bet, both call.

The turn: A(A-5-6)Utg checks, MP bets, I raise, UTG folds, MP 3 bets. I call.

River Q(A-A-5-6)

MP bets, I call.
How did I do?
