I have 2 pair HU, but he bets a buyin

[pokeriseasy]

Villain has been standard aggro preflop, and when he has raised he is following up with a Cbet a good amount, but we haven't played too many rivers on his button. This is his first overbet of any kind. He's also been pretty nitty postflop as he's been folding to nearly every one of my Cbets, and nearly all of my flop check raises and donk bets.

Yea I considered rasing the turn. But vs. somebody as nitty as this guy has been how often does he bet fold an A turn? And say he does call, and a K falls on the river, what am I doing?
