Too Much or Just Right?

[Jeffage]

30-60 online. I have A [img]/images/graemlins/spade.gif[/img]9 [img]/images/graemlins/spade.gif[/img] in the cutoff. Three limpers, I limp (I know a raise is another option here) others behind fold, blinds come. 6 to the flop of 2 [img]/images/graemlins/club.gif[/img]3 [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/club.gif[/img]. Check to first limper who bets, next limper raises, I make it 90 to go. Folded back to the initial flop bettor who calls two cold, the middle guy caps and we both call. Three to the turn of J [img]/images/graemlins/spade.gif[/img]. First limper checks, next bets, I raise planning to not put another cent into this pot. Now the first limper coldcalls and the turn bettor folds. The river is the 7 [img]/images/graemlins/diamond.gif[/img] Villian checks, I change my mind and bet (modicum of value?). Knowing little about him beyond that he hasn't been too out of line in the last few hours, would you check or bet this river? Would you play the turn the same typically?

Thanks,
Jeff
