If there is a straight or flush possibility with "x,x" I bet and reraise on the flop to take it down.

If you are familiar with the player and know he is super aggressive, I like option 3, re-raise the turn. Maybe he'll get just enough rope to hang himself. I think you have him outkicked even if he has an A. The only danger in this is that once in a while he'll show you a set or he'll pair up his lower kicker on the turn or river.

I think the safest of all is to bet it right out on the flop. Hopefully, he will give you credit for the ace and you take it down right there. If he tries a re-steal you can reraise. If he goes all in over the top of me I think I fold. However, this is also probably the least profitable approach.
