Grandmaster Bobby Fischer, pictured above in 1971 at age 28, is considered to have been the world's most brilliant chess player. In his new Fischer biography, Endgame, Frank Brady writes that the chess prodigy was a man of paradox: "Bobby was secretive, yet candid; generous, yet parsimonious; naive, yet well informed; cruel, yet kind; religious, yet heretical. His games were filled with charm and beauty and significance. His outrageous pronouncements were filled with cruelty and prejudice and hate." /AP hide caption
