A dramatic sacrifice might seem like the best way to achieve a dazzling, come-from-behind victory, however, the outcome of most chess matches, depends on the participants' positional skills. The first player to establish a positional advantage gains the best chance of a successful direct attack. This complete guide, written by an Israeli grandmaster, offers valuable insights in developing a more powerful strategic game. It spans a century and a half of international chess, from the era of the legendary Paul Morphy in the 1850s to that of the modern powerhouse Gary Kasparov. The author focuses on common situations arising from practical over-the-board play. Examples - on such themes as key squares, bad bishops, and pawn structures - appear in ascending difficulty, with ample cross-reference. Derived from the author's own coaching manuals, these instructive examples successfully assisted in training Israel's top juniors and the champions of the Israeli women's national team. Chess players at every level will benefit from this opportunity to develop an intuitive grasp of each concept and strengthen their positional play.
