The Artie Maitland-Porridge chess match was a game of chess between Artie Maitland and Porridge. Artie challenged Porridge, under the guise of a chess-playing Cyberman, to chess to win five Imperial shillings from Webley. Artie offerred a sandwich to earn the right to play. The Eleventh Doctor, Clara Oswald and Angie Maitland spectated.
Artie, to the Doctor's displeasure, opened with the infamous Fool's mate, moving his pawn to f4, enabling Porridge to check and subsequently checkmate Artie's king in two moves with his queen, ending the game in a decisive victory for Porridge. (TV: Nightmare in Silver)
