PLO50 JJTTr river line?

I think when You have bluff in your range You Bet sometimes.
You have also bluff in your range when You check raise.

You need to balance your range here depending on how often You choose a bluff line.

Your Velue range is so wide here containing flush to full House.

Sorry, I thought You have AA in your range and op but not the blinds.

I think the best play is 2/3 pot lead or pot Bet. I am not sure he choose a bluff on the River. He Might call most of the time. When reraise come on River, i dont know what happen. He Might have AA but I check sometimes on flop. About 20% of the time, Maybe 30% .

Theory wise I think he should Bet all the Draws on turn. Ace on turn is a scare card to you.

When he mix it up on turn I can image AAxx in his range

Yeah so hands I would potentially x-r bluff are ones with some showdown value but not really beating any river value range. So some trips would make sense or some A9, AT, T9 especially without flush blocker. Hands like AT or A9 with high flush blocker are imo fine bluff catchers. Well T9 is likely pretty nice pot lead as bluff as showdown value is very limited. Straight should not be value betting anyway. Same applies to my leads. Straight is just too thin to value bet even if using 1/3 sizing.

I agree villain is likely betting lot of his draws without showdown value on turn but he does also have fd with flop overpair or nut fd that doesnt necessarily gain that much from turn bet. E.g. hand like AJT8 with nfd doesnt need protection and doesnt really benefit from isolating versus tight range. Villain bluffs should come from some air, Tx and also on this river hand like KK with one club has very limited showdown value. I feel like theory wise 9x should be barreling turn quite a lot but might be occasionally in river range as well.

Do You think he bluffs often on River?
I think we need to look at % of bluff , check, Velue Bet on River and choose the best option.

He Might call sometimes check raise on River.

Well it's not hard to find potential bluffs in his shoes. Anyway he did have nut flush this time and bet 3/4 and called my 3/4 pot raise. Was thinking whatever to just pot but I think it's fine as long as we go on big side. Can't remember his exact hand but it was A8 of clubs so blocking straight flush.

He played his hand bad in my opinion. He gave free card instead of winning pot on turn.

Well I did check his exact holding and this was result:

So he actually had wrap and nfd so exactly kind of hand that doesnt need much protection. This time he would have won with second barrel but he has mediocre showdown value and doesnt necessarily want to tighten my range into point where its questionable if he can even triple barrel on this river for value.

Not sure if his river call is necessarily good. E.g if we think of all nut flush combos. So nut flush is just bluff catcher as I am not value raising weaker. When he has nut flush it will obviously always come with A blocker which is valuable versus hand like A6 and versus some of weakest AA. For most part I would 3bet pre with 115bb effective stacks though with AA. But some rainbow and low suit combos are fine calls imo. He has 8♣: which is relevant but I would think both 9 and T are more valuable for blocking 99 and TT. So its not like worst of nut flush combos but not best either. Should I look for x-r with 96 or T6? I think its somewhat thin and probably better to just lead those for value. But 99+ make reasonable x-r value range.
