You have to call. Villain could have AJ here, and in fact probably does. A small set is possible but is it possible 80% of the time? That' all the beats you, really. Maybe he slow-played a set of Jacks. 55 makes no sense. No, you call.

As for your betting, I might check-call the river after being smooth-called twice in a row without a read. That said, if his river raise put him all-in (i.e. he only had $53 and the pot was over $80 at that point) I might have pushed the river if I was prepared to call a push anyway, and I think i would have been here.
