River Bet Against Donk?

[Lucky]

Villain is 52/20/20. I had been running at 18/14/3, but since table got short, I've had like 73o every hand. So my recent image should be even nittier.

So pf is not great, I Cbet flop; I bet turn because this guy will look up on flop and fold turn a lot. But I get to the river and I'm lost. These spots where I probably can't win without betting, but I'm also going to get called a lot confuse me and probably are spots where I bleed a lot of money.
