This is live. Hero has about 6k, villain covers. Villain is a solid, pretty conservative player both Pre and Post flop. Villain views me pretty much the same way I view him.
9 handed game has been pretty tame.

PF: Hero limps UTG w/ 6 [img]/images/graemlins/heart.gif[/img] 4 [img]/images/graemlins/heart.gif[/img], CO calls, Button raises to 120, Villain in SB calls, BB folds, Hero calls, CO calls. 4 players.

Flop (490): 8 [img]/images/graemlins/club.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img] 4 [img]/images/graemlins/spade.gif[/img]
Villain bets 260, Hero calls, CO & Button fold.

Turn (1010): 3 [img]/images/graemlins/heart.gif[/img]
Villain bets 500, Hero calls.

River (2010): 9 [img]/images/graemlins/diamond.gif[/img]
Villain checks, Hero....

My read was that the hands he would have and bet up until the river like this are 66 & 8s-Js.

My question is should I value bet the river here? If so how much? Also is it better to raise on flop or turn and if so how much and why? What do you put villain on?
Thanks.
