The splendidly named Percival Guy Laugharne Fothergill (1868-1948), who lived at various times in Twickenham, Staines and Isleworth, was a composer of mostly lightweight problems who was active between the 1880s and the 1940s. I’ll be writing a lot more about him for British Chess News in a few months time.

White to play and force mate in 3 moves, against any defence.
