I would have re-raised preflop. You should prefer to play this hand heads up against the original raiser, as opposed to in a multiway pot.

I would also have raised SB's flop bet, as he may have been making a continuation bet with unimproved overcards, such as AK.

However, I would have called SB's flop 3-bet as opposed to capping. SB's 3-bet suggested that he may have had an overpair to your JJ, but you had 6 outs twice to the straight or trips.

SB was unlikely to fold to your flop cap, and you were already heads up at that stage. So I would have called down after SB's flop 3-bet.

The pot was big on both the turn and river, you had an overpair that may have been the best hand, and your opponent was overly aggressive. So I would have called both the turn and river bets.
