Ak deep 4bet pot vs river donk

Don't think we can put AT/55/99 in his range after the preflop action. TT seems unlikely as well. So I'm having a hard time figuring out what he could be holding for him to take this peculiar line. Slowplaying AA maybe? AK/AQ? Going nuts with KK? I think AA is perhaps the most likely, but then I'm not sure why he'd expect you to call an overshove like that when you've already shown some signs of pot control on flop and turn.

I think I'd call it. If he has AA, that'll make a good note.

Pretty rough, seems pretty value heavy , villain has to think you have an ace when you 4-bet pre , bet flop and turn. For all he knows you have AA here you should have more nut combos than him because of the pre-flop action.Villain playing it like AA himself but only 1 combo remains , maybe AK or he some-how called the 4-bet with TT, i would think only a lunatic would play KK,QQ or JJ this way. There is only 1 combo of AA, 3 combos of TT, there are more combos of AK left than there are of his nut hands .

We need 30% Equity and if you give him AA,TT,AK we have exactly that. If you give him over-played AQ obv our equity increases and if you give him AT obv it decreases, AT though would somewhat loose call pre. I think it can go either way on river
