In early 1985 Florencio Campomanes - the now disgraced former president of FIDE, the World Chess Federation - halted the World Title challenge from Garry Kasparov "without result", thus forcing a rematch in the autumn of that same year. This book recounts Kasparov's determined fresh assault on the world title which made him at age 22 the youngest champion in the history of the game.
