Easy fold on river – I’m not even sure raising is a good idea.

I also think flop is close. I can see a case for betting or for check-folding (given this action).

You shouldn’t consider a bet “just positional”. Yes, his position enables him to bet more hands profitably than he could from another position, but it doesn’t mean he can or will bet absolutely anything. It’s important to recognize that he’ll probably bet most hands better than yours, so even if he does have a few bluffs in there (which, importantly, will often be stuff like KT or T9 with significant equity) that doesn’t necessarily mean you should call.

I ended up folding and kicking myself for raising instead of just calling the river. 

The thing I didn’t think about before making that raise in-game is what do I do if I get c/r (no plan. it wasn’t even on my thought-radar). 

It’s good to consider that, but really I think the central problem is what you go on to say, that you didn’t figure to be a favorite even if called. If Villain’s shove is never a bluff (which I believe), then you don’t lose anything by folding to the shove. As long as he will call the raise with enough worse hands to make up for the times he shoves, it is fine and correct to raise for value and fold to a shove.

You’re thinking about this hand well, I just don’t want your take away to be “don’t raise if you can’t call a shove”.
