PS NL50: AQ 3-bet pot facing bluffy line

[ceavou22]

Hi, villain's stats are 25/9/1.67 over 78 hands at the time of the hand. No history. I check the turn for pot control which sort of worked.
I'm pretty sure river is a fold without a better read but his line is very bluffy and I guess missed clubs, badly played PPs might be induced to bet river once I check turn.

What do you put villain on ?
