SB vs BB, What Line do you take?

Have been sitting together for about an hour. Every single time the table folds around to him and it is just SB vs BB he has raised. I have hit one hand before and played back at him. Other times I had air and still played back at him. He folded pretty much everytime on the turn.

Seat 6: SB - Villian $1844
Seat 7: BB - Hero $2184

Villian posts small blind (10)
Hero posts big blind (20)
