Highest break: 123
Qualified as a Referee: 1986
First Professional match: 1992
Most memorable match: It's got to be the 2004 World Championship final between Ronnie O'Sullivan and Graeme Dott. It's the pinnacle of a referee's career. I was 33 at the time and I'm still the youngest referee to take charge of the final.
Most embarrassing moment: I was refereeing a match at the World Championship between James Wattana and Jimmy White. I gave a free ball and for some reason I forgot to take the brown out of the pocket. Luckily I realised before the next shot was played, and put it right.
Toughest rule to implement: The push shot. We often have to rely on the honesty of the players as they are the only ones who know for sure whether they have fouled. They are very good in terms of calling fouls on themselves.
What do you carry in your pockets? A coin, two ball markers and a pen.
Off table interests: Rugby union - I support Newport Gwent Dragons. And socialising with friends.
