The 'modern' era is considered to start in 1969, when the championship reverted to a knock-out tournament format from a challenge format. In the modern game, the best record is that of Stephen Hendry, who won seven times in the 1990s. Ray Reardon won six times in the 1970s, while Steve Davis won six times in the 1980s. Ronnie O'Sullivan has also won six titles, between 2001 and 2020.
