Wait or go (and why)?

I would raise. If you get 3-bet, you can safely fold the turn unimproved. If everyone just calls, you can keep firing on a non-scary turn. The ideal situation is if CO and SB fold and BB calls (or if everyone folds, of course). BB could be very likely just continuing his PF aggression with overcards with a not too scary flop.
