Shove or check river? Comments on all streets welcome.

I've only been playing with the player for about 80 hands. I don't have too many reads on him. He's not a reg. He had 68vpip from the sb. He was moderately aggro. I havent been getting much oop and he has been folding to so many of my opens preflop that I have no real postflop reads on him. I have taken the bet, bet less than pot on turn line before, from the button after he 3bet and checked the flop, he folded turn. I've 3bet 3 times so far and this is the first one he has defended. I'm unsure if I took a good line. I was gonna shove most rivers, but on the q river, I was planning on check-folding.
