$EV of limp-calling with AA on the bubble?

[handsome]

Party Poker No-Limit Hold'em Tourney, Big Blind is t150 (4 handed) converter

Button (t30)
SB (t3195)
Hero (t4290)
UTG (t2485)

Preflop: Hero is BB with X, X.
UTG calls, Button folds, SB folds, Hero pushes.

UTG has AA. According to SNGPT, both a fold and a push are +EV:
$EV Fold $151.70
$EV Push $156.63

Let's say you're UTG. You know that Hero will push 100% with any two if you limp and only call with top 5%, do you limp-call or just push?

I'm pretty sure limp-calling is bad, but I'm curious as to what the $EV of it is. I don't think there's a way to find out by inputting the situation in SNGPT, but if there is, please let me know. Or if anyone cares to do the math .. [img]/images/graemlins/wink.gif[/img]

And sorry for the identity confusion.
