$22 Confused with JJ in BB

[1C5]

Fold, call and see a flop or push PF, what do you like?

Party Poker No-Limit Hold'em Tourney, Big Blind is t30 (9 handed) converter (http://www.selachian.com/tools/bisonconverter/hhconverter.cgi)

UTG (t1660)
UTG+1 (t770)
MP1 (t720)
MP2 (t770)
MP3 (t690)
CO (t905)
Button (t490)
SB (t1205)
Hero (t790)

Preflop: Hero is BB with J/images/graemlins/club.gif, J/images/graemlins/heart.gif.
<font color="#666666">1 fold</font>, UTG+1 calls t30, <font color="#666666">2 folds</font>, MP3 calls t30, <font color="#666666">1 fold</font>, <font color="#CC3333">Button raises to t125</font>, <font color="#666666">1 fold</font>, Hero ?

Given the button's stack size, I push and get it heads up if he calls.

If his stack was equal to yours, I'd call then check-raise all in after a flop without overcards.

I haven't been playin much lately but it always seems when a shortstak like this doesn't push means he has a big hand and wants people to call. Being a 22 I still would probably push.
