So many weird things happened here, that I highly doubt will ever happen again. Yet, as it stands, and based on how the other people played it, I don't think you can play it differently. When you bet $15 and get two calls you might be able to decide you are behind, depending on how much credit you give the guy to cold call with a better hand. Turn card didn't make things worse for you, you can't tell if you are ahead or behind, I would have shoved too.
