$3 NLHE STT: A8 3bet all in

SB: 1,848 (9.2 bb)
Hero (BB): 4,541 (22.7 bb)
BTN: 7,111 (35.6 bb)

Preflop: Hero is BB with :As:
BTN raises to 500, SB folds, Hero raises to 4,516 and is all-in, BTN calls 4,016

Flop: (9,207) (2 players, 1 is all-in)
Turn: (9,207) :Ts: (2 players, 1 is all-in)
River: (9,207) :Kd: (2 players, 1 is all-in)

What are the blind levels at this point? I don't particularly like the shove preflop here.

If this is a 6max sng, you are one away from the money with one player being short. I think I would rather see a 3Bet or a flat here. 3bet accomplishes the same goal as shoving does here , and when we get called we are not in good shape.

^^^Pretty sure this is a 9man and we are ITM.

Button needs to be extremely aggro for you to be reshoving here as we are in 2nd place by far and this shove depends on $EV, not cEV. I'd probably shove AT+ 22+, KJs+, KQo+, QJ+, JTs and possibly flat the top of my range if I think villain is opening very wide.

Most worse hands are folding. You might get some calls from broadway hand that you are ahead of, it depends on how tight villain is. You're likely not getting a lot of folds from much better. A smaller 3 bet does the same job.

What player is in BTN? Fish? Reg?
