If BB is a calling station (with the provided info I'd day it's likely), would callling from the SB make more sense? He going to call until the river and whether we have a hand or not. Just calling preflop allows us to get away from our hand easier if he bets the flop. Our check on the turn broadcasts that we don't have a hand so even passive villians are likely to bet (which is why when we do have a hand we should sometimes ck the turn to induce a bluff).
