TPTK in 4beted pot. Push or fold?

I would most likely just call pre-flop or the UTG player is aggressive.
His 4bet sizing is tricky. Off course the odds are decent, but you are often dominated and even if you hit top pair you have often the 2nd best hand and I would make a tight fold.

As played you hit top pair top kicker and no way I can fold any more. His over shove is weird, but i you fold now you can fold pretty much any flop against him. Than you should fold this hand pre-flop already if you fold top pair now.

AJo is not really hand you want to be flatting preflop. Its either fold or light 3bet. So I dont mind prefop 3bet, though usually I would just fold, but once UTG make clickback 4bet I would fold as default. Pot odds are great but villain range just tend to be like QQ+, AKs or so. Sometimes it could be just maniac villain with random stuff but that is rare.

We see issue of cheap preflop call in this flop. Its one of best ones with top pair and backdoor fd yet its nasty to stack off. But once you call preflop its mandatory call here as SDK said above.

PS: A high flop I would be much more eager to stack off as this preflop line from villain is much more often big pocket than AQ+. So when its like AT7 we beat QQ, KK and only one AA remaining.

Hi,
I liked your notes. If we consider that the villain 4bets only the top of range we have:
AJo VS (JJ+, AQs+, AKo)
Pre flop equity: 25%.
Pre flop pot odds: 5:1
Pre flop odds: 3:1
Pos flop equity: 52%
Pos flop pot odds: 1.8:1
Pos flop odds: 1:1
In that event I would have hit the hand but I don't know if the villain shoves this without an overpair JJ+ then my equity would be 25%. What do you think?

He might shove with A high also if he has them in preflop min 4bet range. More often AK would just shove preflop I would say. But yeah its plausible he has it. You can limit AK frequency by taking just e.g. 1/3 of possible combos into his range.
