RR Pot 200bb Deep OOP with KK as Overpair

[TheBobn]

This hand happened about midway through a session about a week ago. Villain is ymjry00 who runs at 21/6 with aggression by streets of: 3.2/1.4/3 over 250 hands.

I was fairly active at the table, likely running between 18/16 and 22/20.

I was hoping he would reraise me PF and we could get it all in, even at 180bb deep, I would have been happy against this villain.
On to the hand: I perceived his small raise on the flop as either a nut type hand: JJ/AA or a hand making a move on me if he thought my two overs whiffed. After I called, I was hoping to get to showdown relatively cheaply when all of the sudden he does this...he took a few seconds to actually shove, and after the hand I asked him what he had and he said KK but couldn't name the correct suits since I had KK, so I think he was FOS.
