Value bet this river?

I put myself on check/call mode on the river, but I think I should have bet for value a little bit since he showed that he was weak throughout. Thoughts?

yeah i bet turn and check behind on river here. He completed from sb and leads out so I'd put him on Kx with the x being worse than J. Specifically I would think K9o/KTo/Kx diamonds.

I think you have him out kicked here alright. But with the flush draw here you have to bet the turn. Half pot. If you get raised you're out but I don't think thats going to happen.
