A KK hand I can’t let go, early inflection point, please advise

[FishInAPhoneBooth]

I usually never post hands because after about 24 hours my mistakes become relatively obvious to me. But this hand, well more situation, has been in the back of my mind for close to a week now and I would like some feedback.

Situation: 50+5 Party MTT. My image is probably fast and loose since I doubled up a few hands ago getting all my $$ on a flop that gave me a nut flush/gutshot straight draw (with an over card).

The hand: Party Poker No-Limit Hold'em Tourney, Big Blind is t15 (9 handed) converter

Button (t960)
SB (t860)
BB (t548)
UTG (t1273)
<>< (t2009)
MP1 (t1269)
MP2 (t1111)
MP3 (t985)
CO (t985)

Preflop: <>< is UTG+1 with K[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">1 fold</font>, <font color="#CC3333">&lt;&gt;&lt; raises to t50</font>, <font color="#666666">2 folds</font>, MP3 calls t50, CO calls t50, Button calls t50, <font color="#666666">1 fold</font>, BB calls t35.

Flop: (t257.50) J[img]/images/graemlins/club.gif[/img], J[img]/images/graemlins/diamond.gif[/img], Q[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(5 players)</font>
<font color="#CC3333">BB bets t15</font>, <font color="#CC3333">&lt;&gt;&lt; raises to t200</font>, MP3 raises to [t935] , CO folds, Button folds, BB folds, &lt;&gt;&lt; ???

The dilemma: If I hadn’t doubled up so early I might lay this down. Villain probably has a jack, some combo draw, or crap – I am either way ahead or a weighted coin toss. With 750 chips in round 1 my feeling is really “F$&amp;% it I can wait for a better spot.”

But in the instant scenario several factors make the decision murkier: villain saw me go aggro with a draw widening his range of hands; if I lose I will still have my starting stack with a whole lot of time; but if I win I will have tripled up early; if I fold I still in awesome shape.

What does one do?

The pot is laying you 2-1. I would call here.
