[NIX]

When someone donks a scare river like this, it frequently means one of two things. Either a) your opponent hit his draw and doesn't want you to check it through on the river or b) he's bluffing and hoping you'll fold. If you raise, you'll get called or 3-bet by a better hand if situation A is true and will get a fold if siuation B is true. Neither of those things really help you.

I just call.
