Final Pot: $103

Is preflop OK? Table had been reasonably loose-passive, and not tricky postflop at all. I was pretty positive villain had KK/AA preflop, but it was worth the $4 to try and stack him. When I c/r'ed he went into the tank and into his time bank before calling. I planned on pushing the turn. Now what?

Pot is $103, I have $60 behind. Can't fold right? Should I check to keep him from folding KK and let him bet? Or should I just push and pray for AQ, AK, or KK? Villain was new to the table, but hadn't gotten frisky in the 2 or 3 orbits I'd seen.
