A four-part manual of poker science. The first part is devoted to the three primary skills of poker - people, probabilities and money - while the remaining three parts give a detailed account of starting hands selection and simple methods for working out the probabilities relevant to Omaha, Texas Hold'em and Stud. In addition, Mahmood analyses over 100 examples of the most common situations of 'after the flop' play for Omaha and Hold'em and 'beyond the fourth street' play for Seven Card Stud.
