Villain is 9/9 8% three bet over 35 hands. I opened the hand before and have been pretty active in the few hands leading up

Thoughts pre and post welcomed

Shove or fold preflop.
I would go with shoving

Flat >>> Fold preflop. We are in position so our range can be weaker then villains postflop+ great pot odds. Also folding is super unbalanced.

We have tons of Axo and such in our pre open range and we even have to play bunch of those to stay balanced (or if we were to leak by folding too much, we would first be folding those Axo Kxo blocker steal hands), not folding ATs.

If villain does 3b-fold decent amount and has somewhat tight 3b-get it in range flatting is more +ev then shoving in some +ev shove spots ( theoretically obvious if we're in position with strong hand). There is 830 in the pot before villains action so he probably shoves some hands as well, which makes range consideration harder.
We would snapcall shove, right?(folding would again be super unbalanced)

Villain seems good so I would recommend being fairly balanced in this spot.

I like postflop though checking flop and turn are viable as well. Out of better hands AQ, 9X and AT might fold turn and fit villains line, most good hands would bet-get it in postflop on this drawwy board.

+1

Flatting with these stacks is bad bc we`ll be freerolled on ton of boards and he can 3b so many rubbish with that sizing.

LOL wtf?? Villain 3bets 1.6x oop 21bb effective, in what way does this person seem good?

I just rip it given the fact you been active.

yeah 4b shove pre. Flop and turn look std.

Flat pre is so fine, shoving -could- be better but def flat > fold. Bet flop good to fold out ak etc, check turn as he rarely c/c flop and c/f that turn

Edit flat vs the info we have Cause of price
