David Harold is an English former professional snooker player from Stoke-on-Trent. He was known by the nicknames of "the Hard Man" and "the Stoke Potter". He was also the first player on the television circuit to sport a plaster on his chin as a guide for his cue, which is a practice now adopted by Graeme Dott. As an amateur he played as David Harold, but after turning professional in 1991 he was registered as Dave Harold.

Graeme Dott is a Scottish professional snooker player and snooker coach from Larkhall. He turned professional in 1994 and first entered the top 16 in 2001. He has won two ranking titles, the 2006 World Snooker Championship and the 2007 China Open, and was runner-up in the World Championships of 2004 and 2010. He reached number 2 in the world rankings in 2007, but a subsequent episode of clinical depression seriously affected his form, causing him to drop to number 28 for the 2009–10 season. He then recovered his form, regained his top-16 ranking, and reached a third World Championship final. In 2011, he published his autobiography, Frame of Mind: The Autobiography of the World Snooker Champion.
