Forget the ace. If you see good fold
equity => try to steal (like with any other card).
If not, fold. Its weak hand. You will win quite little money if you hit the ace (ace on board will make your value bets too obvious). You can loose a lot to some better kickers.
In general, if you get to the flop, you will be dominated too often and in bad situation to get any value.
Its of course for deep play and cash game.
At short stack at tournament in push/fold phase (like less then 8BB on late position, especially with antes) => shove any ace.
