Alan Turing was not only a brilliant mathematician and computer science pioneer, but also a gifted runner (with a marathon time of 2:46). It is no wonder, then, that he invented a game that combines rigorous thinking and running: Round-the-house chess.
The rules are as follows: It looks almost like a normal game of chess, except instead of opponents taking turns in playing, each player has to run around the house once before being allowed the next move. If you overtake your opponent, you get two moves in a row.
For those living in or near Cambridge (UK), my former colleague Daniel Murrell is organising a Turing chess tournament this coming weekend (Sunday, 23 June) to honour Turing’s 101st birthday.
