Flopped a straight, now what (and when to raise/cap the river)?

*grunch*

Bet the flop. You were the PFR and I think everyone was just giving you the change to lead out on the flop.

Turn screams that SB most likely had a hand on the flop and wanted to C/R you. He either hit his set of 9s (JJ or TT is a 3-betting hand though the SBs PFR% is a little low (small sample size I know), so ???), hit 2 pair like 9[img]/images/graemlins/diamond.gif[/img]T[img]/images/graemlins/diamond.gif[/img], or also flopped a straight.

I would probably cap the river not fearing the flush to much and if he turns over 9[img]/images/graemlins/diamond.gif[/img]T[img]/images/graemlins/diamond.gif[/img] tell him NH and move on. Any other flush, he gets a nice little note.
