This book, whilst a good read, is not an end-all resource for the pass. I believe (and feel free to
disagree with me here) that the classic pass is what should be the primary focus for passers who
want to use this for audiences. The only other one that I use extensively is the SWE shift, but
that's just for when I'm impressing magicians. This book, however, gives multiple different passes
that I don't think merit practicing. If you want to improve your classic pass, buy Miracles with
Cards by Jim Swain. The 10 or so pages in there dedicated to the pass are more useful than what's in
this book. The only parts I really enjoyed from Gary's book were the history of this move and the
chapter about Chris Kenner and his fake SWE, "Shifty".
