Swedish site, swedish crowns. The game plays like NL100.

Been at the table for a few orbits. The table is 7-handed, and is filled with ultraloose aggressive players.

I figure my strategy is waiting for hands, no use stealing as the average vpip was around 30-40 and i witnessed some really funky hands winning showdowns.

BossMedia Game #1100943836: - kr2.50/kr5.00 - No Limit Hold'em

UTG+1: hero (kr809.21)
BTN: Villain 1(kr2023.44) 57/16/3 (3b: 13%) (160 hands sample)
UTG: villain 2(kr905.43) 20/0/0.2 (3v: 0%) (500 hands)

Sb posts the small blind of kr2.50
BB posts the big blind of kr5.00

*** HOLE CARDS ***
Dealt to HERO [A K]
Villain 2 calls kr5.00, Hero raises kr22.50, 2 folds, Villain 1 raises kr40.00, 2 folds, Villain 2 coldcalls kr40.00, Hero... needs a plan for the hand.

So where do we go from here? Since BTNs 3bet% was so high, i felt that a 4bet was an option. The only problem is that if i 4bet i'd feel sick if i got shoved on. Or would i? Getting flatted wouldn't be great either since if i rraise to perhaps 120, then im oop in a ~280 pot with about 680 behind. Any c-bet would commit me to the hand, so seems like i'm pretty much forced to hit my hand here.
Then there's UTG. i don't know what the **** he is doing. What do i make of this guys?

Make it 150. If UTG shoves, I think you have to fold, but right now his range is any PP (and other BS, he is 20/0 afterall). If the other guy shoves, anh, I'm not sure.

dont play with playchips or whatever crowns are

The thing is, This would be a pretty standard 4-bet if it wasn't for the awkward stack sizes and the players tendencies.

If we 4b to 150 we got 20% of our stack invested, what is our plan when a very dry, but missed flop such as say ....

777 lands? We're first to act.

Raise to kr 160 and fold to any shove is the best way to continue.
