Williams' best performances during the 2012/13 season came in China as he reached the semi-finals of the Shanghai Masters and the quarter-finals of the Wuxi Classic and China Open. He also performed consistently in the PTC events, getting to one semi and two quarters.
But otherwise it was a disappointing season for the two-time World Champion and he even joked about retiring after losing in the first round of the UK Championship. He also suffered a first round exit at the World Championship, against Michael White.
In 2011 he reached the final of the Australian Goldfields Open and Shanghai Masters but lost two close matches against Stuart Bingham and Mark Selby.
His 2010/11 season was highlighted by victory in the new German Masters, achieved with a 9-7 defeat of Mark Selby in the final in Berlin watched by a packed house of nearly 2,500 fans.
"I'm really happy with that win, it was a nerve-wracking experience, both in front of that unbelievable crowd," he said after winning his 18th ranking event in all and eighth overseas. The previous season had seen Williams win his first ranking title in four years, beating Ding Junhui 10-6 in the final of the China Open.
Known for his awesome single-ball potting and exceptional touch, Williams first ruled the Crucible in 2000 when he became the only left-hander to win the world title.
He came from 13-7 down to beat fellow Welshman Matthew Stevens 18-16. His second world title followed three years later when he beat Ken Doherty by the same scoreline in another close final. That completed an incredible hat-trick of snooker's biggest titles as earlier that season he had won the UK Championship and the Masters.
He has won the Masters twice and his first Wembley crown came in dramatic circumstances in 1999 as the final against Hendry went down to a respotted black, Williams potting it to a baulk corner after Hendry had missed a chance to a centre pocket.
Williams made the first competitive 147 of his career in a match against Rob Milkins at Sheffield in 2005 - and that was handy timing as it scooped him a £161,000 bonus. He became the fifth player to make a maximum at the Crucible.
In 2004, Williams was awarded the MBE in the Queen's Birthday Honours list. "It is a tremendous honour for me, for Wales and for the game of snooker," he said.
In his teenage years, Williams was a keen boxer and won several fights before being on the wrong end of a thumping from an older, heavier boy which curtailed his brief career in the ring. His hobbies include playing golf and five-a-side football as well as driving exotic sports cars and motorbikes. He and wife Joanne have sons called Connor, born in 2004, and Kian, born in 2007, and their third boy was born in 2013 .
