Hi there, 

I would definitely bet the turn for value. I think if we bet the turn we find out exactly where we are in that hand. With your read I would expect him to call his draws as well as weaker Js, 89s, 78s so we get value from that hands.

When he has a monster here he’s going to raise you. I would not expect him doing this with his draws. When he raises big, I think you can comfortably fold against this villain. When he makes a small raise you can call and see the river. He’s probably not the guy who bluffs on the River (regardless of the rivercard). When he bets here pretty big it’s an easy fold. 

When get called I bet small for Value on the river. I think he would never bluffraise here but look you up with weaker Jacks and even a pair of 8s, 9s, Ts. 

Some thoughts when check the turn: When he is weak what hands call the flop and bet that turn? Is he betting a weaker J here? His sets he would have raised on the flop. When he bets (for a weak villain): 55 and 67 this hands I would expect him to bet bigger (just a guess).
Now when I go through the hand I think his bet is most likely a weaker J (given the action he could bet KJ, QJ for value), even a pair of 8 (89, A8, K8), 99, TT what he’s not sure what to do with (especially when you frequently Cbet).
I do think when he is on a draw he wants to see a free Rivercard and checks.

I haven’t looked at the results yet, I hope I’m not way off here :o)

PS: Question: You wrote you are blocking the Ace Nutflush that’s why you check that turn. I don’t understand how that affected your turn-decision. Can you help me out here? In that situation I don’t even think about that, maybe I should. Thanks in advance.
