The 2005 Royal London Watches Grand Prix was a professional ranking snooker tournament that took place between 8 and 16 October 2005 at the Guild Hall in Preston, England.
John Higgins won in the final 9–2 against Ronnie O'Sullivan. In the final, Higgins set two records: His century breaks in the seventh, eighth, ninth and tenth frames marked the first time a player had ever recorded centuries in four consecutive frames in a match during a ranking tournament.[1] He scored 494 points without reply,[2] the greatest number in any professional snooker tournament, until Ding Junhui made 495 points without reply against Stephen Hendry in the league stage of the 2007 Premier League.[3]
