Tough spot pre-flop with QQ

[PoBoy321]

Ultimate Bet No-Limit Hold'em, $.50 BB (10 handed) http://216.119.70.224/converter/hhconverter.pl

UTG+1 ($49.50)
UTG+2 ($46.80)
MP1 ($45.25)
MP2 ($10)
MP3 ($48.75)
CO ($26.45)
Button ($19.15)
SB ($39.50)
BB ($49.50)
Hero ($58.10)

Preflop: Hero is UTG with Q[img]/images/graemlins/heart.gif[/img], Q[img]/images/graemlins/spade.gif[/img]. MP2 posts a blind of $0.50.
<font color="#CC3333">Hero raises to $2.5</font>, <font color="#666666">7 folds</font>, SB calls $2.25, <font color="#666666">1 fold</font>, <font color="#CC3333">Hero...</font>


Hmmm... the HH screwed up. MP2 pushed for $10 and the SB called, so the action was back on me.

I had no reads on the SB in this hand. I figured that the short stack likely had a mid-pair or a decent ace, but SB's call of an EP raiser and a MP pusher had me worried.

Your move?
