In 1980, George Low wrote in "Education" magazine:Mr. Leonard Barden, manager of the junior squad, traces the resurgence of interest to media coverage of the Fischer–Spassky duel eight years ago and its sequel between Korchnoi and Karpov six years later.In about 1972–73, he recalls, the selectors started casting their nets much wider than the Home Counties grammar schools where the recruiting ground had traditionally been. He and his colleagues looked through the results of a lot more tournaments all over the country. Those who had real talent were encouraged to go in for the National Junior Squad Championships and to enter adult tournaments. They were also given the opportunity to play against adult grandmasters in 'simuls' (simultaneous games involving 20 or 30 boards). Mr Barden now has 500 players on his books in whom he takes an active interest, following their tournament games and writing to suggest alternative strategies in their games.
