Brightwell started playing
Othello in 1985, after finding himself sharing an apartment with fellow mathematician and Othello player
Imre Leader. He has finished three times as runner-up in the World Othello Championship and is a 5-time British Champion, and has served as chairman of the British Othello Federation and as editor of the British Othello Newsletter. He created the Brightwell Quotient, often used in Othello tournaments, to resolve ties. ==References==
