In this classic chess work, I. A. Horowitz presents the study of chess openings in a logical, easy-to-understand manner, not beyond the grasp of the player who has learned little more than the rules of chess. To begin with, an outline and discussion of the principles and concepts of opening play, common to all openings. Then, in turn, an account of the most popular openings—attacks and defenses—and a breakdown of their individual moves and grand plans, with an attempt to show how the tactical forte of each move ties up with the strategical idea.
