100NL: Villain leading on flop, Shoving on turn? To call?

[TPTK77]

I have stats now on villain but yes... this was the 2nd hand of the session, so I didn't have anything on him. The reason I was worried with this call of my raise, and then an insta shove on the turn was that if he had a flush or straight draw, he would've shoved over the top of my raise on the flop since he's half stacked. By just calling, I figure he already has a made hand. The question is whether its more likely hes holding KQ,KT,K9 or hands that beat me.
