The Secrets of Brother John Hamman by Richard Kaufman and Alan Greenberg Page 38 et seq.
Personal Comment: The First Twist aka Hamman's Twist I already covered a few months ago. This gets rid of the extra card. Is it an improvement? Yes, I think so. But just a little one. One I would not care about, considering the fact that the initial setup is much easier to accomplish in his first version. Tastes are different.
