Betting the turn is ok because he can't possibly have a made hand that checks two flush draws so you might as well protect but checking isn't horrible either. As played this is an easy river raise...you 100% have the best hand. If I am him and I flop a straight draw with 45 or turn a flush draw after cbetting and getting called I am pretty psyched and am double barreling the turn every time. There is no way he checks the turn to see if he hits and then bets. This is like air 80% of the time IMO and is one of those ill-conceived bluffs that you should be profiting from heaps if you are a good hand reader (i.e. callable without the 6 river). The other 20% of the time I'd say he has Jx and is making a value bet (weird line though).
