Originally released in 1988, Sklanksy and Malmuth updated Hold em Poker for Advanced Players in 1999 and called it the 21st century edition. Poker has, and continues to change over the years, and the updated edition reflects some of those changes. The primary changes include updated hand rankings, as well as particular sessions about non-standard (Shorthanded, Wild, extra loose) games. As the rules of poker continue to change, adjusting your play for who you are playing against becomes more and more important, and the sections on these non-standard games are invaluable for the serious card player.
