Of course it's up to your position on the table...if you are in the start position, like UTG I would suggest you just to call the BB and watch what other players will say and if someone raises, make a re-raise....if your'e in end position you got almost all information about other players...pushing all-in with aces..hmm...if there are few short-stacks against you, go ahead, but if there is more than two big-stacks against you, the best play would be call but, of course, you can try to win a huge pot..its up to you and position&situation at the table
