BB Checks, Hero bets 200, BB raises to 400, Hero folds.

BB got his stack to over 3200 in the first 5 hands, including cracking 2 players with consecutive Full Houses. Has been quiet since. I have played only 3 hands, once grabbing the blinds with a 3BB raise, once winning with AK and C betting a whiffed flop and once showing down AK and winning with two pair. I thought I had slightly too many chips to push. After the flop, I had no clue, what to do.

Hand 2

Blinds 75/150

UTG 348
Button 4669
SB 2403
Hero 580

UTG folds
Button raise to 300

Hero (A [img]/images/graemlins/diamond.gif[/img],10 [img]/images/graemlins/heart.gif[/img]) folds

I'm trying to make it to third here and the small stack will go broke before I do.

Any advise will be appreciated.
