ANSWER: Pankaj Advani
Explanation:
Ace Indian cueist Pankaj Advani clinched his 17th world title after he thrashed his arch-rival Mike Russell of England in the IBSF World Billiards Championship at Doha in Nov 2017.
Advani beat Russell 6-2 (0-155, 150-128, 92-151, 151-0, 151-6, 151-0, 150-58, 150-21) to defend the 150-up format title he had won in Bengaluru last year.
Advani, winner of maximum number of world titles in any sport by an Indian, increased his total by one more as he dominated the remainder of the final.
He clinically constructed lethal breaks of 151, 151, 151, 145 and 110 to completely dismantle his longstanding rival.
Earlier in the tournament, Advani had overcome fellow Indian Rupesh Shah in the semi-finals 5-2, while Russell got the better of Singapore's Peter Gilchrist 5-1.
