This is a collection of 69 antated games played by 17 of the greatest chess players in history. The games are nicely laid out in descriptive tation. Included with each of the games is a biography of the players. This book is a good read. Even without playing over the games, readers will find it enjoyable. Although the games are labeled upsets, t all are considered upsets in the prospective of history. For example, Morphy's defeat of Anderssen in 1858 might have been considered an upset at the time it was played when Morphy had just arrived in Europe, but we w recognize that Morphy was a stronger player than Anderssen. This collection includes four games lost by Bobby Fischer at near his peak plus games lost by each of the World Champions from Steinitz, Lasker, Capablanca and Alekhine to Botvinnik, Tal, Petrosian and Spassky. Samuel Reshevsky is the ideal person to write this book because he played all of them except for Steinitz.
