it all depends on the type of player you are. If you are going just to get paid, then you probably fold or call and hope for a decent flop. If you are aggressive and think the other players will fold, you shove. Position has a lot to do with it also. if you are last to act and no one else has called the BB , then a shove would be in order, if there are many players behind you, i would fold and live for another day.
