I have always trouble to play against these huge station donks.
I agree on bet or c/r turn and I should be prepared to play for stacks against these donks on these nice turns!
Somehow, I didn't had the balls to do it ... don't know why ...

Thinking again about this hand, we have showned a lot of passiveness so villain might put us on TT-JJ, 66-77, A9, A8 or 43. So why push that river IP? I think he wants us to call most of the time.
If we had bet the river and he had pushed, this would be a different story.
