I think it was in one of Lou Krieger's books where he tells a story about a lady that calls a bet on the river with k high or something and she wins. He asks her why she called and she says 'because i knew he had nothing". He goes on to say that if you think your opponent is bluffing you should always raise rather than just call. I don't practice this advice, nor do i even believe its good advice in most situations. This is one situation where, if your going to call, a raise could be a much stronger play to put pressure on the SB to fold a bad pair. It does look like a suspicious bet from the BB, so I wouldn't fold. I think a raise may be the play.
