Bet the flop and take control of the hand.

You're up against two weak (or so we assume) opponents plus a random BB hand. You have second pair, good kicker and no reason to believe you're not ahead at this point. Giving a free card in this situation is bad.

If called, you bet the turn, of course. Up to this point the hand plays itself.

If you're raised on the turn you have some thinking to do, but after you have signaled strength with a flop bet, your opponents actions will be easier to interpret.
