Checkers is a video game based on the board game checkers. It was made for the Atari 2600 by Activision. What's notable about this version of the game is that the screen turns black when the opponent AI is computing moves to make against you, and given how fast the Atari 2600 is, a regular game can take nearly an hour to play.

Winslinator carefully chooses moves that minimize the amount of time the AI takes to compute its own moves in order to beat the game in record time. The strategy used here is not one that can beat the AI in the fewest moves, but one that can beat the game in the least amount of time. You can read the author's notes for more details.

There's a video that trims out the loading screens for those in a hurry.
