ESPN investigates the historic Kasparov vs. IBM chess games

The battle of wits between IBM and chess grandmaster Garry Kasparov is one of the biggest moments in the history of artificial intelligence. After conceding defeat, the Russian suggested that the IBM team had cheated their way to a victory, something that the company, to this day, refutes. A new film, from Nate Silver's FiveThirtyEight, seeks to shed some light on the accusation and what prompted his allegations. Directed by Hollywood uber-producer Frank Marshall, the documentary examines the controversial 44th move and how a simple computer error proved to be Kasparov's undoing.
