pretty simple question

Unless you have some definite read on the guy that he'll frequently fold the turn, I'd check behind here too. There's a lot on this board that his action so far indicates that he could have hit. What are you worried about giving a free card to? Aren't you still drawing? I just see check-raises here way too often, and don't think a minimally-reasonable player would fold here.

If you think you have the best hand, call the river UI.

The chance that he donates a full BB on the river with a bluff, stands to make you way more than you give away by checking if villian is behind in this small pot. Plus you have to call c/r.
