Razz is new territory for a lot of players, and a great money-making opportunity for those who want to become good at it. I'm not there yet but working on it and I've been playing Razz pretty regularly lately... so far (knock on wood) I've only had one losing session.
The only Razz reference I've found in print is a section of the book "Sklansky On Poker," which is worth a read. On the surface it's a simplistic game but it has some interesting nuances... and lots of players who don't seem to know their way around it, at least at the lower limits.
