NL50 150BBs deep - Interesting river situation

[Baintz]

Villain has been fairly active raising from LP. He stacked me once when he raised 88 from button, called my rr from SB, flopped quads and stacked my QQ.

The following hand is also worth noting in that he can check a good hand on the river.

My image is tight. Was planning on folding to a turn c/r, so when he calls I thought his most likely hand was AK, AxQspade AxJspade, although he could have a boat and be letting me bet it for him.

We both have about $50 behind on river. I'm not sure he'll call a shove on river with just a pair of aces, but also, if I bet less and he c/r, I'm almost surely beaten, but would be getting sick odds to call.

CO checks, Hero???

So how much do you bet on river? And are you calling a c/r?
