Nice.

If villian isn't a player, then his preflop raise isn't a speculative hand or a low pocket pair, right? That means it's a big pair or big overcards. Him checking the flop is pretty revealing, I think, the only hands that fit in those categories that he checks the flop with are KK (he's probably trying to find a way to get the money in and froze up) or a lower big PP like QQ - TT (because he is straight forward and afraid of the K). I don't think he checks this flop with AK or AA. He also wouldn't raise you on the turn with QQ - TT just to see if you have anything since it's a protected pot due to the short stack going all in, so basically I don't think he is making a move here and I'm actually kind of worried. Am I totally off?

That being said, I call his bet, and probably check/call a reasonably sized bet on the river. If he has the nuts he is not going to put in a huge river bet.
