The Chessmaster is a long-running series of chess video games made for various consoles and computers. The NES version of the game comes with various ways to tweak the CPU opponent, such as allowing it to think while you make your move and whether or not it has access to a predefined set of moves to make early on.
FractalFusion plays against a CPU opponent set at "Newcomer 1", the easiest difficulty setting, and utilizes the Bongcloud variant of the Wayward Queen Attack to checkmate it in record time.
