2 Pair or Full House: Call, fold or raise on the river?

[Kid Sheleen 05]

I ran into this situation at least twic today and bet it differently in both instances. How would you bet this on the river?

3-bet the turn and go from there.

SB checks, Hero checks, MP1 bets, MP2 folds, SB calls, Hero ?? The way you played it I would raise here.

Bet the flop. Your lack of a flop bet is probably why you got beat with J9 on this hand.

3-bet the turn.

Bet the river, call a re-raise.
