($55) 18 person SNG 1st hand - value within shark scope??

[pokerlaw]

OK - so this is a $55 turbo 18 person. I like to start off fast in these and I like my preflop raise, although in a 9 person game I think its very not optimal. Anyway, here is the hand:

PokerStars Tournament, Big Blind is t20 (9 handed) Converter on pregopoker.com

UTG (t1500)
UTG+1a (t1500)
MP1 (t1500)
MP2 (t1500)
MP3 (t1500)
CO (t1500)
Button (t1500)
SB (t1500)
Hero (t1500)

Preflop: Hero is in BB with J[img]/images/graemlins/club.gif[/img] K[img]/images/graemlins/spade.gif[/img]

OK - now I am questioning his move. I certainly represented a good hand so far. Does he have AT or something? I don't think he has an overpair cause just about anyone would have raised pre-flop (either originally or to my reraise) with one. He took awhile to reraise me, and I am thinking its either he is making a move, or he had the nuts. So I chose to sharkscope him.

here are his results - 409 games played, down $7,301 with a -43% ROI and $43 avg stake.

he is obviously totally awful, and I deduce that he is FULL OF SH*T.
