Sklansky et. al. have written the definitive book on 7-card stud. It is fairly easy to read and quite complete. It is probably best for middle and higher limit games but the tactics can be adapted to suit lower limit and spread limit games. It is a must for poker players who do not want to loose atll their money when they visit the casinos and poker clubs. You can be sure that if you sit at tables in Atlantic City, Vegas, California, Foxwood etc. the player(s) across the table from you has probably read this book, and you will be at a significant disadvantage if you have not. It is worth a buy, but you must read it carefully and practice.
