Query: Good player, poor author and teacher

This book is almost totally useless in teaching gin rummy to a relatively new player. It utilizes primarily an anecdotal approach using exclusively examples from games in which the author has played. While this may be interesting to the author's friends and competitors, it is of little or no interest to a member of the general public. Do not waste your time with this book unless you know the author.
