A Documentary about the Epic Match Between Garry Kasparov and Deep Blue

Seventeen years ago in New York City, brooding chess champion Garry Kasparov sat down to take on an opponent he had vanquished just a year earlier: the IBM computer, Deep Blue.

FiveThirtyEight and ESPN Films follow the drama of those nine days in a short documentary film, “The Man vs. The Machine,” directed by Frank Marshall. The story — part of FiveThirtyEight’s new digital short series, “Signals” — hinges on a single move, the 44th move of the second game.
