The Theory of Poker by David Sklansky discusses theories and concepts applicable to nearly every variation of the game, including five-card draw (high), seven-card stud, hold em, lowball draw, and razz (seven-card lowball stud). This book introduces you to the Fundamental Theorem of Poker, its implications, and how it should affect your play. Other chapters discuss the value of deception, bluffing, raising, the slow-play, the value of position, psychology, heads-up play, game theory, implied odds, the free card, and semibluffing.
Many of todays top poker players will tell you that this is the book that really made a difference in their play. That is, these are the ideas that separate the experts from the typical players. Those who read and study this book will literally leave behind those who dont, and most serious players wear the covers off their copies. This is the best book ever written on poker.
