$55: Shortstacked with pocketpair. When to get fancy instead of push?

[AA suited]

lvl5 (75/150), 5 players

bb=3000 chips
sb=2000
button=2000
co=1000 (HERO= pocketpair)
utg=2000

No reads. Folded to me.

i usually push low/medium pocketpair here, and most of the time the blinds fold. If i had JJ or above, i usually would min raise and hope for a call to get more chips. then push no matter what on flop.

How high of a pocketpair would it take for YOU to try to trap, instead of pushing preflop?
