Book excerpt: Computers have permeated almost every facet of modern chess, yet few players know how to gain the maximum benefit from working with them. Computers function as playing partners, opening study tools, endgame 'oracles', tactics trainers, sources of information on opponents and searchable game databases. Kongsted provides practical advice on how to use computers in all these ways and more. He also takes a look at the history of the chess computer, and how its 'thinking' methods have developed since the early days. The book features an investigation of human vs. machine contests, including the recent Kasparov vs. Deep Junior and Kramnik vs. Deep Fritz matches, in which honours ended even.
