Sherlock or Doctor Who – who would win in a chess match?
While Sherlock is undoubtedly a highly intelligent human being, the Doctor would probably have the edge. Not only does he have a bit more life experience (a mere 900 years), he has a greater knowledge of chess as well: we have frequently seen him in past regenerations sit down to play with friends and enemies alike. His robotic dog K9 did get the better of him once, but K9 had been programmed with all championship games since 1866.
Besides, Sherlock doesn't really get along with board games. In the Hounds of Baskerville, John tells Sherlock they are never playing Cluedo again because "it's not actually possible for the victim to have done it".
