10nl Full Ring - How did I play this hand?

just 4bet pre - what's a proper 4bet size though? does it depend on if you're IP or OOP?

These sizings just scream TT or JJ, I might just fold flop or turn - dunno though - I might just call too
villain seems like a tight reg, so I'm leaning towards folding
but these bet sizes make him look like a total fish, so we might have to call down?

Agree that you should 4b pre. As played, i think calling down is the only choice

IF he's tight pre then he has a higher concentration of 4b calling hands not less.

I would just jam flop and c'est la vie. Next hand

4bet or call pre is fine especially vs those who 3bet light very often.

Flop is easy shove when he pots. He's not folding with this sizing. It's a cooler if we lose.

Fish cbetting large is a pretty good sign of top of the range, but it's also the sign of the master station who will call off pretty much all QQ, AJ, KJ, FDs, even some straight draws, sometimes AK etc

I don't think it's JJ very often. TT rarer. I think it's AA, QQ, AKhh, AQhh, KQhh and other stuff we beat but has ok eq vs our range. Plus there's so many bad turns, I don't want to risk letting them off the hook. But it is not a fist-pump spot no. We underplayed preflop so technically OOP should have more bluffs, but i doubt it. We can't ever fold after this anyway. I think it's a kind of protection shove that likely makes more EV now while it still beats some hands, rather than targeting some fictional bluff range that could either slow down or nuke our EV quite rapidly

What exactly are we protecting from though? Draws (especially super draws that you described) dont fold for less than pot, hands like QQ or Jx have two to five outs against us, and both of those categories will bet turn unimproved most of the time anyways.

And i would actually consider folding on a 9h turn for example if villain shoved

Yeah I'm not saying it's hardcore either way. I'm just justifying why I said what I said and I stand by it. You can snap a lot of these mixed descisions without extensive brainpower and mixed freq shoves can be debated ad infinitum. It's always going to be right from both angles.

But this does not seem like a spot where it matters almost at all. I could just as easily challenge you to prove why the solver is wrong and this is a full freq call? But it would be pointless imo

Preflop 4-bet is fine here. Flatting just keeps you guessing postflop.

If I were to 4b pre, what size 4bet would you choose?

I normally 4bet to 25bb when someone has 3b to 9bb but in this hand they have 3b to 12bb. So maybe $2.80 (28bb)?

You can also 4b bluff from time to time (ideal candidates: AQo and KQo). You certainly can't do this if the only hand you 4b with is AA. Villain is effectively in EP/UTG position (from 6-max perspective), but they can still do some weird stuff, they can have AK/QQ and it's just 100 BBs. With AK and QQ I'd say yes, call, but here just 4b/c and save yourself trouble. If he has AA, you're gonna go down anyways. If he has AK and won't hit his pair, you have effectively lost money (unless he decides to bluff you all the way). He may as well let his foot off the gas pedal with QQ-JJ on A/K-high boards, but could have shoved them preflop and boom - you have lost money again.

26 BBs.
