Blind battle rivered two pair

[Requin]

Villain is a regular, I haven't seen him much but he seems very aggressive. My image is probably tight PF (like 19/15) but overly aggressive postflop. Is a river shove too thin? Would it be better with more money back? I felt that he'd check A9 and worse aces on the turn fwiw, maybe AT.
