Fold AA? (postflop)

[NJpokahplaya]

This hand is from a pokerstars 5$ rebuy tournament, a little after the rebuy period. The villain in this hand seemed straighfoward and bad (called too much), but that's only based on 20 minutes of hands since the rebuy period. Table is 9 handed and blinds are 100/200. Only relevant stacks are listed.

Villain (CO) ~15,000
Button ~11,000
Hero (BB) ~11,000

PREFLOP: Folds to CO who limps, button limps, SB completes, I raise to 1,000 with black AA. CO calls, button calls, SB folds.

FLOP (POT = 3200): J [img]/images/graemlins/heart.gif[/img] 9 [img]/images/graemlins/diamond.gif[/img] 3 [img]/images/graemlins/club.gif[/img]
I lead for 2k, CO minraises to 4k, button folds, I call.

TURN (POT = 11,200): J [img]/images/graemlins/diamond.gif[/img]
I check, CO pushes (I have 6k left), I ????


Here are my thoughts as the hand played out: Preflop needs no discussion. On the flop, when he minraises my mouth starts watering as my hand is almost always good. I was trying to figure out the best way to get all the money in and thought a push might scare off top pair type hands, so I decided to just call and let him hang himself on the turn. Also, if he is bluffing, just calling gives him a chance to fire another barrel while pushing obviously takes down the pot as is. Would anyone play flop differently? If you do 3bet all in the flop please give an explanation as to why you think it is best.

Now the turn brings another jack, basically the worst card in the deck. I vomit in my mouth a little and check (seems like the obvious play here). He thinks for maybe 3 seconds and puts me all in. A jack seems like the most likely hand here, but he could be betting the scare card with a draw or just going crazy with a mid pair. So, call or fold?
