(109) Bubble: Over the top with AJ?

[bennies]

PartyPoker Regular Tournament, Big Blind is t (4 handed) Converter on pregopoker.com

CO (t3205)
Hero (t4308)
SB (t5652)
BB (t6835)

Preflop: Hero is in Button with J[img]/images/graemlins/spade.gif[/img] A[img]/images/graemlins/club.gif[/img]
<font color="red">CO raises to t2000</font>, <font color="red">Hero raises to t4308</font>(allin), <font color="gray">SB folds</font>, BB calls t3708, <font color="gray">CO folds</font>

Anyone like calling instead of pushing now?

(By the way, I tend to agree with Kristian and BigT that folding is better. But assume we have AK instead of AJ, should we just call the t2000 or push as I did?)
