I see no point in betting the river. The only point would be if you think hes going to call with something you beat or fold something you dont beat.
I seriously doubt he called your turn raise with 99 / TT and those are probably the only hands he would fold now that beat you.
If he had a flush draw, you most likely still beat him and he wont call anyway.
What other hands can he call with that dont beat you?
Maybe he will fold
[Jd]? Thats about the only hand that your river bet is +EV against (assuming he folds it which I doubt).
