Definetely bet this river?

[jsnipes28]

Villain hadn't done anything out of line in the past 100 hands here. Should i bet this river, and if so how much. A large bet more than 1/2 pot, or overbet is really only going to get called( by preflop raiser) by 88, JJ. I think that QQ, KK, AA can find a fold here to a large bet. So it's either bet like 35-40 as a value bet or check and hope to induce a bet from overpairs against my AJ. Thoughts on how i played the hand are welcome.
