Live 1/3 full ring $400 max bi

Hero (BTN): tag image. just sat down 30 mins ago. ~350
Villain (UTG): argotard old european. playing approx. 50/20, from a small sample size. opened AQ UTG for 12. according to friend on table, he bluffed jammed K3o with little equity, binked river, and hes been sucking out on most of the table. c/c flop and turn ATo on QJxxx and x/f river. has been bullying table with his 1.2k stack. ~1200

Pre ($4)
V opens for 20. hero calls w/ AQ calls. I thought the huge sizing was pretty weak and i thought i was doing pretty well against his range. The table was also on the tighter side of the spectrum. also i didnt want to play a 3bet pot w/ an spr or almost 2 against an argotard, since i was pretty tired. and i dont think hes 4betting worse.

Flop ($44)
K44
v cbets $20. hero calls. i didn't think he was cbetting 66-QQ here so the only real value he could have were AA and AK, but he would've opened AK smaller pre. i block both hands anyway lol.

Turn ($84)
Q
v insta bets $100, quickly throwing a single $100 chip into the pot. hero???

I think that flatting or 3! is ok. I'd be 3! Aqo pretty consistently, this player type calls with worse all day. Good flop call, fold turn.

pre - 3! to 85. instacall any shoves

flop - call is fine. small sizing is air or a big hand.

turn - I would call. turn doesn't really change anything, but you still pick up some equity.

river - would call any bet and expect to see a 4 or air.

This all equals an absolute slam dunk 3-bet pre:
-You read his larger opening as weak, know you're doing well against his range so for pure value you can 3b.
-The rest of the table is tight, so you know nobody is going to try and squeeze, so you can 3b safely.
-Playing a 3b pot w an apr of almost 2 against an agrotard where you remove tough decisions for yourself when you know you've got his range crushed is absolutely ideal as far as I'm concerned.

Turn is a fold. There's no draws on the board. You beat nothing of his value range, and his line should usually never be pure air in this spot.

Unless he does this with QJ, AQ or JT I think it's a fold ott, I'd just think 'thanks for overbetting and letting me know how good your hand was'.
