Blind steal gets pushed back at, call or fold?

[AceofSpades]

Hero is on a blind steal and short stack pushes...before I get a chorus of "fold preflop" my read on BB was that he was tight..

PokerStars No-Limit Hold'em Tourney, Big Blind is t200 antes 25 (9 handed) converter

SB (t12000)
BB (t22210)
UTG (t21490)
UTG+1 (t8000)
MP1 (t11420)
MP2 (t3170)
Hero (t14295)
CO (t15600)
Button (t3485)

Preflop: Hero is MP3 with 7[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">4 folds</font>, <font color="#CC3333">Hero raises to t800</font>, <font color="#666666">1 fold</font>, <font color="#CC3333">Button raises to t3460</font>, <font color="#666666">2 folds</font>,

It's [t2660] to me for a pot of 4785

call or fold?
