It is folded to sb,very aggressive and tough reg who limps and I raise to 0.7$

with AKA4.He calls.Flop is K89.He checks I bet 2/3pot to encourage calling with

weakest hands, although I expect him to float on this board with every open ender,every flushdraw and every pair plus gs.He calls.

Turn J,he leads 2$ into 3$ pot,which is kind of fishy,i don`t give him

to much credit for nuts and call with intention of calling brick rivers.He will have

TJ combos here more often than QT ,tho he can have 7t.

River is T,which is terrible card,he bets 2.5$ into 7$ pot.

Usually people don`t bluff with this sizing,but is possible that he bluffs with

tj or busted hearts.I was thinking raising here is probably better than calling,

but can I credibly rep here AQ nuts and make him fold that one specific

hand QX?Any merit in raising turn also?

Bad texture for your hand so it becomes very marginal spot ott.
It's plausible he leads turn w/ nuts and no/weak redraw understanding this turn card is better for his range and you will xb a lot.
Otr on gutshot texture he will have Qx a lot and won't fold it most likely. You also don't rep AQ very well thus it seems ok to give up.
Folding turn also seems fine.

Villain often bets with the nuts or a weak str8 with this sizing.

You rarely win with a call and probably don't get villain to fold enough with a raise.

Unless I have a lot of history and notes on villain, I'm probably folding and swearing a bit.

You dont have top set

I had AKK4ds

just fold turn, your equity is bad even if he semibluffs a lot
