QQ overpair vs. unknown. line check. 50NL

[GiantBuddha]

So this is a pretty common/simple spot. Overpair on in a 3-bet pot OOP. Villain is total unknown, my second hand at the table. If he has AA/KK does he just get my chips? Am I getting any value from 99-JJ here? How would it be different if I held TT or AA here? I'm interested in general theory of this type of spot more than the particular hand itself.
