Call. Fold or Push?

[willperkins]

I realize I made a major mistake not raising preflop. I tried to get cute and try to win more than the t100 in ths small blind.

What is my play after SB raises?

Party Poker No-Limit Hold'em Tourney, Big Blind is t100 (5 handed) converter (http://www.selachian.com/tools/bisonconverter/hhconverter.cgi)

Button (t1650)
SB (t2305)
Hero (t1340)
UTG (t750)
MP (t1955)

Preflop: Hero is BB with K/images/graemlins/diamond.gif, K/images/graemlins/spade.gif.
<font color="#666666">3 folds</font>, SB completes, Hero checks.

Flop: (t200) 6/images/graemlins/club.gif, J/images/graemlins/spade.gif, 5/images/graemlins/diamond.gif <font color="#0000FF">(2 players)</font>
SB checks, <font color="#CC3333">Hero bets t100</font>, <font color="#CC3333">SB raises to t200</font>.

Hero??

DEFINITELY WITHOUT A DOUBT ABSOLUTELY do not fold.

I'd re-raise to 600 and push the turn assuming he doesn't push back.

Reraise easy. I probably push.
