HUSNG -- What to do here...

[Nichomacheo]

Villain hasnt been too tricky. He's the type to bet out on a paired flop and fold to a small raise. I don't remember him limp/calling yet. I would probably say that his minraises are strong, but I cant be sure. I have no idea what to do here:

PokerStars No-Limit Hold'em Tourney, Big Blind is t50 (2 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

Hero (t1375)
Button (t1625)

Preflop: Hero is BB with K[img]/images/graemlins/club.gif[/img], A[img]/images/graemlins/spade.gif[/img].
Button calls t25, <font color="#CC3333">Hero raises to t200</font>, Button calls t150.

Flop: (t400) 7[img]/images/graemlins/diamond.gif[/img], Q[img]/images/graemlins/club.gif[/img], J[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets t200</font>, <font color="#CC3333">Button raises to t400</font>, Hero scratches head.

The stack sizes are so awkward. Call? Fold? Raise?
