First hand of tournament, no reads on villain. This is a $16 tourney and I'm leaning towards a push, but not quite sure what the best action is here

I fold. He's doing his best to tell you he has a King. Why not believe him? There is a chance that he is make some fancy play, but this is less likely at the 16s. If you fold you're in fine shape, the blinds are still low and you can fight back.
