I think you should lead the flop, really. Mostly this is for value, since it won't do a whole lot to protect your hand. And usually you won't win the pot either, but I think you'll win more than your share.

Anyway, after you checked, I think you should call two more back to you.

Possibly BB has a very strong hand, such as AA or a set of sevens. Or he might have been checkraising because he though Button's bet was a weak stab at the pot and BB felt he could chase people away and win unimproved with his AK.

Anyway, I don't really know what BB (or anyone else in the hand) has, but I do think there's a decent chance you're ahead at the moment.
