Either betting turn or check/calling to disguise and get max value on the river. Unfortunately if that was your plan his check behind sucks. River is a check/call imo, he can have several hands that beat you but you still beat a lot in his range and he can definitely have bluffs in his range given the scare card and your weakness on turn and river.

I like your PF sizing no issues there.

OTF I other than beeting a bit smaller to keep some smaller draws in I think its fine.  checking will get you no info, wont build the pot if you hit and more importnatly will turn your hand face up after calling a raise.

I am fine with the call of the 3 bet on the flop  if you are planning to raise/put it all in on the turn.  So I dont like the check at all.

I call the river as I feel there will be enough 8s, bluffs overpairs str8s and smaller flushes to justify it.  but I wont be surprised if im beat.

I call, he turned over 88 for quads. 

The intent on the turn was the check/shove, trying to get cute.  I am thinking the right move is a jam since I had just shy of a pot size bet left and only beat by the suited A.

I have spent much time in analysing this hand.

Firstly, I allocated the villian's preflop flatting range to be JJ-22 and ATs-AJs and KQs.

When the villian min raises, I first assigned a range of sets, TT-JJ and AJ-AT of diamonds. Against this range it is clear that a 3b jam on the flop is bad so the question now becomes call or fold.

However, after analysing in further detail his range becomes even stronger as we can take TT-JJ out of his range because I don't believe he is ever min raising these hands. This now leaves the villian with sets and two combos of better flush draws, so, as played, the turn is an easy ship with the SPR of 1 and you are just going to get snapped by his entire range, which now only has 1 combo of better flushes.

As played, the river is a snap fold as you simply don't beat anything.
