How many chips do I need to re-raise here?
 

Or is folding always the right play?

PokerStars No-Limit Hold'em Tourney, Big Blind is t200 (9 handed) converter

BB (t12980)
UTG (t30579)
UTG+1 (t20862)
MP1 (t4140)
MP2 (t20605)
MP3 (t12900)
CO (t6190)
Button (t8295)
Hero (t29875)

Preflop: Hero is SB with T[img]/images/graemlins/club.gif[/img], T[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">4 folds</font>, <font color="#CC3333">MP3 raises to t1425</font>, <font color="#666666">1 fold</font>, <font color="#CC3333">Button raises to t3825</font>, <font color="#666666">2 folds</font>, MP3 folds.

Final Pot: t5425

EDIT: Of course it looks so obvious now he's holding a monster, at the time it felt like a steal/resteal. Guess I answered my own question.

Easy fold.
I'd expect MP3 to have less than QQ, and Button to have QQ+.
