In my opinion your raise size is okay. The villain got his flush on the turn and won?

I bet on the turn is fine and so is checking. If I bet the turn I'm looking to check decide on a lot of rivers. Once we go 3 streets even though we have a set, with the flush and straight coming in on the turn it's hard for them to call with worse.

I'm with @Harvie on this one. Unless villain is an absolute payoff wizard it's hard to get three streets on this texture.

I don't mind the turn sizing although we could even go 40% as river is set up pretty ugly now for us to fold to a x/shove.

I think all the 2 pairs will check back and I don't see much in the way of missed straight draws that would have called the flop raise and turn bet when flush comes in so it looks like a x/fold in this specific spot.

I think we were 5 handed on the flop and we could so easily be behind already. Turn is a death card imo even if we were ahead on the flop and that's fairly thin. I'd be checking this to the river from turn, not sure if I'd check/c or chk/f though to be fair, but river is bye bye beautiful 9s for me as played after villain calls turn.

Thanks everyone, yeah he turned the nut flush. Hard to let it go while playing though.

When a fish bets less then half pot on such a wet board with so many people in the hand, its usually either because he has a draw himself and thinks he has fold equity or a marginal made hand that doesn't want to let scare cards fall off for free. I think we can x/r bigger for value since he is fishy and we want to also push others out (don't want to go 3 way to the turn) Him being agrro usually means he will donk with his strong made hands (because hes affraid of scare cards) or x/r them but usually will also have tones of semi bluffs himself so he won't respect your raise too often.

I would x/r 4x on the flop, then bet 1/3 pot on the turn then x/ probably fold the river.

I just don't think these types of guys bet 5 into 12.50 with AQ and 2pair type hands on the flop.

You need to remember here that when seeing a flop 4 way continuing ranges are typically much tighter. Oh course your hand is awesome but it means villains will be continuing much less with non-nutted facing lots of action. I think the way I would play this is x/r flop bet turn check river. On the Ax river I don't expect to be paid off by Qx at all so by betting you're getting action from 2 pair and better which on this board will include lots of flushes and the JT straight.
