Kind of an annoying spot and not sure what to do here. Live 1/2 PLO, when someone pots initially it's $15.
No significant reads on the players. We are new to the table.
Hero has $540
CO covers,
BTN covers,
SB only has $130 (We didn't realize until later in the hand)
Preflop: Hero A

in BB
Folds to CO who opens to $15, BTN calls, SB calls, Hero pots to $75, all 3 players call
Flop: J

SB donk shoves for $55, Hero calls (not sure if should be doing something else here), CO folds, Btn shoves, hero?
We only have about ~$390ish back and there is now $465 in the pot. What are we doing here? Would anyone shove initially when facing the small sb donk?
