I think you played this well. I doubt that villain would bet river with sets/2 pair. Even if he bluffed OTT there is too big risk that he hit a flush OTR.

OTF: Bet bigger! Like 3/4 pot or more. Board is drawy and you want value

As played I simply muck the turn. The straight, the flush and twopairs get there. The problem is that I don't see enough bluffs in his range to make this a profitable call. And Qx would be scared of the flush itself.

Fold turn. You may be already dead there.

I think the hand was played correctly. No, there is no fold on TURN, but it is 4 flush board on the river, so your opponent double donks you - on turn when flush come in and on the river - so, he most probably has flush. His AF is quite small, if he had a set on the flop - he most probably will XR on the flop to get most value from your possible draw. So, nice fold.

I think we can call the turn, but it's probably close. Folding would also be fine. The thing is that we can't put him exclusivelly on flushes when he donks, I believe, especially because of the fact that people usually tend to check/raise flushes. Also, some regs would bluff donk those situations. When we call the turn, we have to fold the river, imo.

Sudden turn donk when draws complete- we can fold and do not bother.
