In $1 $1 live plo game with lots of straddles, we got garbage hand A344 in bb, no hearts.

Flop($30): Ah 3h 2s

Sb checks, we lead full pot, 2 players call, one of them is sb.

Turn($90): 9!h, check, we pot, utg calls and sb shoves cca $390, its for our stack, utg is already AI.

What do we do here, we have $300 behind...?
