I would have folded this hand pre-flop.

Once you get to the river, betting depends a lot on your opponent. Since he just sat down, I assume you know little about his play. All he has done so far is check and call, giving us very little information. I would usually check this down unless I felt confident I would get called by a lesser hand. I have no idea what BB has, and we can see for free. I would check.
