Who bets this river?

[Ironman]

Another 3/6 UB full table game.

My cards are 3 [img]/images/graemlins/diamond.gif[/img] J [img]/images/graemlins/heart.gif[/img] 5 [img]/images/graemlins/spade.gif[/img] A [img]/images/graemlins/spade.gif[/img]

I have a good handle on my opponents. I've played against all of them so Pokertracker is keeping me up to speed on their aggressiveness.

I'm in middle position.

And the table views me with these stats (if anyone else is looking):

24.10% VPIP
+5.9 BB/100
64.6% Won $ at SD
1.92 PF raise


Pre flop

3 folds to me, I limp, 2 more callers, SB raises, BB folds, the rest of us call.

SB has a good VPIP number but is a losing player in my database.

Flop (5 [img]/images/graemlins/diamond.gif[/img] 9 [img]/images/graemlins/club.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img])

SB bets, 3 callers

Turn (2 [img]/images/graemlins/club.gif[/img])

SB bets, I raise, fold, fold, SB reraises, I cap it (with my pair of 5's), he calls.

River (9 [img]/images/graemlins/heart.gif[/img])

he checks.....

Who bets the river?

Am I getting 3/4'rd or the one doing the 3/4'ering?
