I got few hands on Villan at this point, but he seems fishy. I decided to just call his flop bet in order to entice him to make a bet on the turn with a KQ-QJ JJ sort of hand and get foolish... when the turn came i decided to make a big raise in order to make it look like i was stealing, since his turn bet seemed weak to me.. he waited for a big (maybe 7-10 secs) before making the bet, and it was smallish. Anyway he calls and checks to me on the river.. whats my move now? Make a valuebet or check it down for pot control?

If you think he has any Q or JJ I don't mind a raise since a flop raise looks weaker than a turn raise.

As played I vbet this river

Villain has committed 1/3 of his stack and you should definitely make a value bet on the river, I would bet about 15 here but if you decided to make it look like a steal, just shove it in and he will take his time and call with a lower kicker every single time
