2 pair facing difficult call on the turn

[TheSug]

I'm just getting started playing NL Cash but this looks very similar to a line I've seen Villains take Limit HE. I wouldn't be surprised if he has A/K, A/Q or 9/9 here. His flop check-raise was to ensure some value and his only line on the turn is to bet and hope you feel attached enough to your hand to have you call/raise. Fold.
