Played on PartyPoker so no HUD stats in replay. Assume villain is unknown.

I think this is a standard AA 3bet. I'm not too sure on the sizing though, too small or just right?

Checked hoping he would fire a shot, unfortunately not.

Given he didn't bet the flop I led out. I didn't want to miss out on any potential value if he had connected with the board in someway or another.

So we're only beat by KQ and Q8. I think it's highly unlikely the villain has Q8 in this situation, I don't remember them being too fishy. KQ is certainly a possibility however and if it's what the villain is holding, I suppose a check back on the flop kind of makes sense from his point of view. Is the call too nitty? I feel like given that there's only two hands that beat us and that it's very unlikely he's holding one of them we should have shoved after his raise.
