Preflop I'd fold because despite his fold to 3b we need a hand with better hand strength esp. considering we're unsure what we're even doing postflop.

Flop: he folds to 3bets 83% of the time so when he calls he's likely going to have a good pair and maybe AK. He's also passive so we can get to sd by checking down against AK.

Turn: Bomb it again because TT/QQ/Jx are likely folding.
