Any reads?

I don't like it. That turn card has changed nothing and unless he was floating the flop with complete air he isn't going anywhere. People don't fold flush draws at this level which makes up a decent part of his range (yes he could have a J high flush draw or something technically giving you value but he has the A/K/Q high one so much). He also isn't folding an 8 or probably 66/77 (maybe even a 5).

If you had reads that he calls flops but folds turns then a bet would prob be fine.

If the turn was a scare card like a spade or an ace or something then a bet would be ok without reads. You're more likely to push him off a better hand when the board gets scary.
