TPTK, semi deep against a tag

[AZplaya]

Villian here is 17/14, he hasen't been too active. Our only history is I've 3 bet him twice in about 80 hands and he's folded. He doubled up with top set against a donk about 10 hands ago. He should have me at 21/17ish.

dont have the hh but this is the jist of it:

Hero ???

Okay so I checked the flop because I'm WA/WB against his range, and if I stack off on this flop this deep against this villian AQ is rarely good imo. Anyone hate the flop check? How about turn and river? I think he checks behind alot of 1 pair hand with showdown value. Thoughts on bet folding vs. check calling?
