QQ no-brainer?

about 12 hands into a single-table WSOP sub-qualifier ($9+1 - 1st/2nd get seats in a $36+3, 3rd gets $12) on Party. Opponent has been somewhat loose, calling min raises pre-flop, limping from EP, etc. but has folded to flop or turn bets everytime thus far. he has shown no cards and I have not done much other than post blinds.

Party Poker No-Limit Hold'em Tourney, Big Blind is t30 (8 handed) converter

BB (t980)
UTG (t1015)
UTG+1 (t575)
MP1 (t1435)
MP2 (t890)
CO (t985)
Hero (t700)
SB (t1420)

Preflop: Hero is Button with Q[img]/images/graemlins/heart.gif[/img], Q[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">1 fold</font>, UTG+1 calls t30, <font color="#666666">3 folds</font>, Hero raises to t95, <font color="#666666">1 fold</font>, BB calls t65, <font color="#CC3333">UTG+1 raises to t575 (All-In)</font>, Hero...

I see one of two scenarios here:

1) people don't limp re-raise all-in unless they have AA, KK or AK so i'm either way behind or a small favorite. Fold?

2) it's a $9+1 on Party after all and the guy is just as likely to have 88 or A9s. Easy push.

even if #1 is the likely scenario do we push hoping for AK and the coin flip knowing another $9+1 will be starting in seconds?

Would the decision be differnt if this was early on in a MTT or a Satellite Qualifier where only 1st moves on?
