Kasparov, the 13th world champion, reflects on the destinies and creativity of twelve previous champions and their rivals, on the sesquicentennial struggle for world championship. Examining famous games under the microscope of powerful computer programs, the author changes many previous assessments and, in essence, sums up the development of chess in the 20th century. This volume is dedicated to the “uncrowned kings” of the past and the first four official world champions - Steinitz, Lasker, Capablanca and Alekhine.< /p>
