He was known by the nicknames of "the Hard Man" and "the Stoke Potter" (conflating his home city's pottery industry and his profession of potting snooker balls).
He was also the first player on the television circuit to sport a plaster on his chin as a guide for his cue,[citation needed] which is a practice now adopted by Graeme Dott.
Harold was renowned for both his very strong defensive play and his unusual cue-action, with which he is able to unleash a great deal of power on a shot without using backswing on the cue.
[citation needed] He never repeated this achievement, although he reached his second ranking final in the 1994 Grand Prix, losing 6–9 to John Higgins.
He qualified for the final stages of the World Championship with a 10–4 win over Mike Dunn, but lost 10–3 at the Crucible in the first round proper to Shaun Murphy.
He took time out before the deciding frame to leave the playing arena and consume a couple of bananas, returning replenished to finish the job with a clearance on the colours.
This gave rise to the affectionate nickname "Bananaman" on the Betfair snooker forum,[citation needed] referring to a children's TV character who gained superhuman powers.
Harold also put up a battle against Shaun Murphy in the next round, but eventually lost 5–3; the last frame set a record at the time for being the longest ever in snooker history (93 minutes and 12 seconds).
Harold remarked after the final that, aside from claiming the World Championship, his one other remaining ambition in the game is to score a victory over O'Sullivan, who he has never beaten in a ranking tournament.
In September he beat Shaun Murphy 3–0 in the newly formed World Open in Glasgow but subsequently lost in the next round to Jamie Cope 3–2.
Harold subsequently failed to qualify for the next four ranking events, losing to players such as Ali Carter, Barry Hawkins, and Cao Yupeng.
