I would bet $136 for a couple of reasons. He's not going to bluff you often after you halfpot it with only $150ish behind where he could be interested in shoving the river if you check. The other reason being a halfpot river gets looked up with a wide range, especially since he called a large turn. By betting $136 you get value and can still fold if he shoves which he won't without a jack most likely.
