JJ - Overpair - river question

[cuQa]

Hey, didnt have any information about the opponent.

What's your move now? Should I bet or just check behind?
Do you think there is a possibility to get value of a "valuebet" with that board and especially that river at all? If you think there is a chance to get value out of a "valuebet" how much do I have to bet then?
