I would say it is a really easy value bet, 2 "really"s is pushing it. It is not thin when you think of his turn range and our river range. And raise pre on button!
River is a clear check imo. We are only hoping for calls from a weaker two pair, the straight was made, his range contains flushdraws that have missed and aren't gonna call so don't really see the value in betting river. Just hope our hand is good.
