The Brokenwood Mysteries S05e01

The dazzlingly clever and always entertaining Raymond Smullyan takes an unorthodox approach to chess puzzles by treating them as mysteries–with Sherlock Holmes as guide and mentor. The key concept is retrograde analysis. Rather than figuring out how to achieve some end from a given arrangement of chess pieces, the game is to examine the board and deduce what has happened in the past: On what square was the White queen captured? or, Is the White queen promoted or original?…To enjoy these problems you need only know how chess pieces move.

The York Mystery Plays are a cycle of originally performed on wagons in the city.

Join Holmes and Watson as they examine interrupted games to deduce prior moves. A series of increasingly complex chess mysteries culminates in a double murder perpetrated by Professor Moriarty.
