Villain here is pretty loose/bad, plays ~60%VPIP pre and doesn't 3bet at all. SB is a shortstacker that plays very solid most of the time, I believe here he has a very, very tight range in this spot.

My open is a bit on the loose side, but with the fish and his stacks it's definitely playable. Anyone hate the open? After BB 3bets, I'm not sure if I am thrilled to call or disgusted to be sandwiched vs very strong range and a deep stack behind me - thoughts?

Postflop I am torn again on the hand - I can't stack happily against anyone, yet I have a hand that I want to continue on and I can potentially bluff some cards if I get to the turn and besides that, I have a wrap against a fish deep. What should my game plan be? Should I also expect SB to check his AA**+nfd ever? Should I just fold flop?
