 FACT: Francis is shown looking at a yardage book, or a series of  hand drawn diagrams of every hole at The Country Club. In reality,  yardage books did not come into use until the 1960s, first by Dean  Beaman and later popularized by Jack Nicklaus.  Harry Varden is shown laying Francis a "stymie" during the playoff.  A stymie occurred when a player’s ball blocked the path of his  opponent’s ball on the green (the balls not being within six inches  of each other). This only applied to singles match play. The playoff  for the 1913 US Open was medal (stroke) play and the stymie rule  would not have been in effect. This rule was eliminated in 1952 by  the USGA.
