Whats your play here

Whats the play here. I am starting to think some raising preflop.

PokerStars No-Limit Hold'em Tourney, Big Blind is t400 (4 handed) converter (http://www.selachian.com/tools/bisonconverter/hhconverter.cgi)

Hero (t5394)
UTG (t2576)
Button (t3275)
SB (t2255)

Preflop: Hero is BB with J/images/graemlins/diamond.gif, K/images/graemlins/spade.gif.
<font color="#666666">2 folds</font>, SB completes, Hero checks.

Flop: (t675) J/images/graemlins/heart.gif, 3/images/graemlins/diamond.gif, 7/images/graemlins/club.gif <font color="#0000FF">(2 players)</font>
<font color="#CC3333">SB bets t800</font>, <font color="#CC3333">Hero raises to t1600</font>, <font color="#CC3333">SB raises to t1830</font>, Hero calls t230.

with these blinds and the stacks in play, you could easily push this PF over SB's complete. post-flop is perfect. if you're beat you're beat.

push preflop.

everything else is fine
