IMO the villan here only believes u here if you had c/c the flop and maybe lead the turn. Looks like he has invested so much by the river he is never folding. He has pretty much committed himself(or made his decision) on the turn. Maybe a 4 Bet pre would establish where you are in this hand since you are playing this hand OOP. What range does he put you on when you flat overcall his 3bet 88+ but when he sees an 8 on the turn its unlikely you have 88 here and if you got there on the river then oh well and he fells like he put too much in and now he cant fold.

 Did he have fishy tendencies? In this case you are never blowing him off AA he is married to his hand! He only sees his hand and you end up leveling yourself, IMO

GL on the grind!

I’m trying to keep this pot small. c/c flop eval turn which is a safe turn so I would probably allow him to continue bluffing (if that’s what he’s doing) by checking with intention of calling or if I felt villain was passive I may lead here with a smallish amount so I can dictate the size of the pot if called. This is where I differ from the logic of “call turn, call river if nothing changes” idea. If this villain bets the river he is saying I have 88-AA and he’s betting for value so I can easily c/fold here. You would only beat bluffs at this point. 88, 99, JJ-AA all has you at that point. What do you think his possible value range could be that you have beat? Right there isn’t a value range you have beat and if he has the other TT oh well.

If he decided to 3 barrel you with AK be patient you’ll find a much much better spot later on. You are 250BB’s effective. If you played the hand a little more passive in this spot you’d have lost a small fraction of your monster starting stack. If you flopped a ten you’d have doubled through the guy that can’t fold an

I also disagree with the idea that AA is just a bluff catcher here. If you power play TT like this in a 3 bet pot OOP JJ-KK are all part of your range.
