Re: Bet this river?
 

I think this is a clear value bet.

I can't see UTG folding for one more bet on the river. I doubt he's putting you on the flush. I just don't think you will get check raised her very often when behind a random opponent.

Following the action I think AA or KK could be there and they will call you.
