Button seems like a typical "CR donk" and has a really wide opening range in CO & button. It definitely includes hands like T9 off. I do have a note that villain will call postflop without too much of a hand and to attempt to double barrel him. I had been abusing his late raises a bit earlier this session and he had folded preflop to my other 3bets and squeezes but haven't played a hand for a few orbits.

Effective stacks $220. Hero is BB with [4c].

3 folds, Villain raises to $7, SB folds, Hero raises to $24, Villain calls.

Flop: [6h][2h]

Hero bets $38, Villain calls.

Hmm, seems like he has a pair this time.

Turn:

Hero bets $80,

Good or spew?

good.

you must have a plan if he shoves.

its very important to make the correct fold if he shoves as you only have 14 ish outs at best, so to call off the rest of your stack you would need some where between 3:1 4:1

Pot is 125 on the turn, and you have 160 behind and something like 15 outs, I like push much more than betting 80, especially when you can represent AK.

I have an issue with preflop, though, IMO it is a fold most of the time preflop. 64s is not hand that you want to go to war with OOP.
