I don't think there is any value in betting here as I think all his two pair type hands would have jammed on me on the turn. I am putting him on lots of draws that ended up getting there. Any six beats me here, and club draw, and A (which he could have floated me IP two streets since I think he thinks that I've been playing back at me).

His sizing is small and I feel like he knows when I check here my range is weak and the river didn't improve me. Looks like a value bet to me. Is there any chance he could be going for thin value with two pair type hands? 

I think we can find a fold here since almost everything villain floats us on the flop and turn gets there on this river. Also, if he were bluffing me I think he would just jam it not make this small sizing (also I can't really think of any hands he has here that would bluff me except missed backdoor diamonds and a 2x which turned an OESD).

What do you guys think?

Thanks!
