Reading Bobby Fischer Goes To War: How The Soviets Lost the Most Extraordinary Chess Match of all Time. I followed this event closely when it was news. Now Fischer is back in the news due to the recent granting of Icelandic citizenship to him. An avid chess-player at the time, I had no idea what Fischer was doing outside of the moves of the game, it was my first introduction to the notion of gamesmanship, bizarre as his form of that was. Finally a writeup of what occured, and hopefully a full explanation of the motivations.
Update/Review: You really have to be very interested in this topic to want to read this. It did fill me in on some of the events, which I only barely remembered via NY press coverage at the time. It most made me wonder why Iceland wanted to take him back in. Reinforced my impression of Fischer as an embarassment ... Although it seemed like Fisher-Spassky progressed interest in chess at the time, it has progressed very little since then.
