What do you think about how I played this hand?

I would gii preflop, don't like to trap here being OOP to 3bettor in 3way pot.
As played, wp.

My gut says this is a 4bet jam spot. Btn is playing very aggro right now, so you are way ahead of his 3-bet range and dominating him a decent percent of the time. With the sb flatting there's a ton of dead money in the pot making it well worth the steal if you get them both to fold. There's always a small chance that the btn wakes up with AA/KK here, or that the sb was trapping, but you have blockers that make it less likely. Plus, I expect players at these stakes to possibly call off with AQ or KQ, which is obviously great for you. Your stack size is also just big enough to fold out some small pairs that are flipping with you. I'm on my phone and can't run the math right now, but again, my gut says this would be a very +EV shove.

Even w/ only 29 hands here, I think we have a general idea of BU overaggressiveness. With AA or KK I don't mind calling his 3b preflop, but here I'm jamming this preflop I'm probably even jamming AKs as well since we're oop. Trying to play AK oop vs two players just sucks when don't hit your flop and you sacrificed so much fe preflop. When you shove preflop in this spot, I think that the BU can call with a lot worse. But when he doesn't you still pick up a sizable pot on his folds.

just 4b jam pre,as played nh

You get in w tp 3 ways and are worried? Then play pre diff
