Afternoon Hands - HAND #3

[Gomez22]

True 1/2 - Table seems semi-loose PF, but plays tight-passive after the flop (now that I've been here for maybe 20 hands or so). For any who DON'T know.. True has $1 SB & BB at 1/2 limit... just so you don't think I called from the SB here.....

I'm in SB with 9 [img]/images/graemlins/heart.gif[/img] 3 [img]/images/graemlins/diamond.gif[/img]

UTG folds, UTG+1 folds, MP1 limps, folded to button, who limps, I check, BB checks.....

FLOP(4 SB): 9 [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/club.gif[/img] 8 [img]/images/graemlins/spade.gif[/img]

I bet, BB calls, MP1 calls, button folds.

TURN(3.5 BB): J [img]/images/graemlins/heart.gif[/img]

I check, BB checks, MP1 checks.

RIVER(3.5 BB): J [img]/images/graemlins/club.gif[/img]

I bet, BB folds, MP1 calls....

Thoughts here? Would you continue betting the turn in this situation? Usually I don't have a problem doing this, but for some reason, I checked it through. Seems a little weak to me for some reason.
