It's a reference to the 1984 film "Wargames", starring Matthew Broderick, who plays a computer-savvy teenager who inadvertantly causes a DOD supercomputer to begin a nuclear escalation with the Soviet Union.
When Broderick's character first contacts the DOD computer, he thinks he's logging into a game company's computer. On the list of the computer's games (actually war simulations), he sees "Global Thermonuclear War". When he tries to get the DOD computer to play it, the computer initially responds "How about a nice game of chess?"
Another famous quote from the film is the same computer saying, "The only winning move is not to play."
Yes, I remember the movie but didn't recognize the dialogue. That was a cute premise.
A friend of mine years ago was a movie buff and a computer whiz. He compiled lists of all the famous computers (and robots) in movie history.
One of my favorites has always been "The Forbin Project". I think this movie might have been shown under the computer's name "Collosus".
The computer's revelation "There is another system" is the key dramatic development. Haven't seen it in years.
And Matthew Broderick's computer was an IMSAI. :)
