Singaporean Peter Gilchrist has won the International Billiards and Snooker Federation (IBSF) World Billiards Championship, beating world No.1 David Causier in the final played in Leeds on Wednesday night.

The 45-year-old, currently ranked fifth in the world by the IBSF, stunned 40-year-old Briton Causier 1,500-1,085 in the long format final to finish first among 59 competitors. In the long format competition, players win if they reach 400 points for the group stages, 1,000 for quarter-finals, 1,250 for the semi-finals and 1,500 for the final.

Gilchrist, who also won the world title in 1994 and 2001, enjoyed a perfect tournament. In the group stage, he won all four matches, beating England's Ian Williamson (400-145), India's Subramanian Venkateshwaran (400-65), Australia's Anna Lynch (400-40) and Vietnam's Kien Nguyen Trung (400-69). In the last eight, he defeated India's Rupesh Shah (1,000-853) and in the semi-final, he overturned a deficit of more than 100 points to vanquish Alok Kumar, also of India, 1,250-916.

He hopes the latest win will see him add more world titles more regularly. He said: "The last time I won this was 2001. I won it in (1994), so it's like every decade. But I'm not going to wait until 2020 now - I want to do it next year as well."

The England-born Gilchrist, who took up citizenship in 2006, now coaches the Singapore national team. Playing in Singapore's colours, he won the 2009 and 2011 SEA Games gold medals in the English billiards singles.
