I have only been on table for a few hands. I have raised one hand out of the 4 hands I have been on the table, didn't go to showdown. Stack $220

MP+2: Young asian kid who I have seen playing higher stakes often, never played with him Stack $300

BTN: Older asian male, never seen him before. Does not look like a good player,

BB: Looks like a gambler, older slicked back hair, gold chains and rings. never played with him. Big stack,at least $1000

Effective stacks $220 for all.

Hero raises AQ to $15, in MP, MP+1 raises to $45, BTN calls $45, BB calls $45, Hero calls $30.

Flop (Pot is $180)
89Q
BB bets $65, Hero?

Fold preflop, out of position vs almost everybody and if you call the pot will be roughly 1 SPR with AQ vs. ranges that should dominate you, not exactly ideal. As played fold the flop, too likely at least 1 person has you beat.

Preflop I fold. Too many calls on the reraise are leaving you OOP in a hit/miss situation. Flop is an obvious shove. Not exactly happy when BB donks into the crowd but you have TPTK and an SPR of 1, your pot committed.

Against unknowns, fold pre OOP with this hand. We're only happy when we flop a straight+ really (or trip Qs), and we aren't deep enough to try and make a flush/trips/straight.

Given you see BB as a 'gambler', and he made this sort of bet, I'd say the main part of his range is QT-AQ in my experience; he can also have TT-JJ, and all 2P combos. Sets are more likely to slowplay or c/r. As such, we're likely crushing his range. I don't expect him to fold TP+ here very often.

Even though I'm not happy about MP1 being behind us as the 3-bettor pre, your description of him leads me to believe that he could quite possibly fold AA/KK to a shove here. He's folding AK and JJ to a shove always regardless, and likely AQ too. QQ is discounted due to blockers.

BTN is pretty much a non-factor here imo, since his range likely includes AT+, 22+, and is folding to our shove very often, but often has some equity against us.

EDIT: As played, shove.
