“Robert James "Bobby" Fischer (March 9, 1943 – January 17, 2008) was an American-born chess Grandmaster, and the eleventh World Chess Champion.” – Wikipedia This movie is not about Bobby Fischer. It’s actually about Josh Waitzkin’s childhood and chess.
“In this film, Josh Waitzkin's family discovers that he possesses a gift for chess and they seek to nurture it. They hire a strict instructor, Bruce Pandolfini (played by Ben Kingsley) who aims to teach the boy to be as aggressive as Bobby Fischer. The title of the film is a metaphor about the character's quest to adopt the ideal of Fischer and his determination to win at any price. The main conflict in the film arises when Josh refuses to adopt Fischer's misanthropic frame of reference. Josh then goes on to win on his own terms with the kind of gracious sportsmanship that Fischer rejects.” –Wikipedia
In real life, Josh wrote a book titled The Art of Learning : A Journey in the Pursuit of Excellence, where he discusses how he learned (some would say mastered) two different disciplines- chess and tai chi.
