The Theory of Poker

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 today's 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 don't,
and most serious players wear the covers off their copies. This is the
best book ever written on poker.
