How to play a combo draw >200BB

A little confused here...Villian is 16/11/20(!) I have over 800 hands with him. Ultra-aggressive, likes to shove.

River: ($67) 9 (2 Players)
Villian checks, Hero checks

Pot Size: $67.00 ($67 Rake)

I was considering a raise on the flop, but he usually doesn't donk out unless he has a big hand (prefers to C/R). I also didnt want to get blown off the hand. IF you were to raise, what would a good amount be?

When he checked on the river, I considered 1/2 potting, but decided against it as there arent a lot of hands he would give up at that point (possibly 56 or A5h). Spew or no?

Thank you in advance.
