handlers to stop playing. Koltanowski had his own organization, the Chess Friends of Northern California, which resisted the USCF rating system and dominated Northern California Chess through the mid-1960s. Koltanowski later decided "if you can't beat 'em, join 'em". He won election as President of the United States Chess Federation in 1974. He also directed every US Open from 1947 until the late 1970s. He was sometimes referred to as the "Dean of American Chess." Perhaps Koltanowski's most remarkable accomplishment was that he made his living entirely from chess. He wrote many books; his best-known work is Adventures of a Chess Master, published by David McKay Co. in 1955. In it, he recounts primarily his tours giving blindfolded simultaneous exhibitions. He also wrote books on the Colle System which he sold by mail order. He taught a system which would enable even rank beginners to get out of the opening with a playable game. This saved his students the trouble of memorizing vast amounts of chess opening theory. However, he never played this opening himself against strong opponents. Koltanowski's books contained many statements and anecdotes which were factually incorrect. They were also lax in terms of spelling and editorial standards. Koltanowski died of congestive heart failure in San Francisco in 2000 at the age of 96. Blindfold Knight's Tour Koltanowski's most sensational chess entertainment was the ancient exercise known as the Knight's tour, in which a lone knight traverses an otherwise empty board visiting each square once only. Of the countless patterns for achieving this feat, there are trillions of sequences for performing the more restricted version known as the re-entrant (or closed) tour, wherein the knight on its 64th move lands on its original starting square. For Koltanowski, who claimed to have a "phonographic memory" (a keen memory for sequences), the trick relied on mastering just one re-entrant pattern. He could begin on any square in the sequence and complete the tour by rote. However, it was his original twist that gave Koltanowski's performance dramatic value well beyond the mechanical moving of the knight through the memorized sequence. Koltanowski began his tour with a large chalkboard divided by lines into a grid eight squares by eight. As he solved problems on a large demonstration board, audience members were encouraged to come onstage to enter words and numbers into the squares. By the time all 64 squares were filled, it
