NL50 AA faces heat on turn

[chris216]

Villain is 29/11/1.57 over 120 hands.
A couple of hands before this, I had KK and he called my pf raise oop. Flop came 299, he check-called my cbet and then turn was another 9. I decided to try zeebo him and just pushed when he checked to me(is that good?). He tanked, wrote in the chat "very tempting" but decided to fold. I am not completely sure what to make of this. Anyway does the Baluga theorem apply here? I mean it would probably be a fold if he check-raised me, but I don't know what to do here.
