During the UK Championship, we're looking back at some of the most memorable moments on this day in the history of Snooker. Today, we reflect on the one that got away for Willie Thorne in 1985...
The heavy-scoring Leicester cueist was one of the best break-builders in the history of Snooker - notably hitting over 200 maximums during practise.
He was a star during the sport's boom in the 1980s and part of Barry Hearn's Matchroom stable - singing and appearing in the music videos for Snooker Loopy and the far less successful Romford Rap.
Thorne was beginning to establish himself as a major force to be reckoned with when he reached the Final of the 1985 UK Championship, and built a 13-8 lead over Steve Davis going into the start of the evening session.
The defining moment in the match, however, saw Thorne miss a simple straight blue off its spot to squander a chance to stretch his advantage to 14-8 (he would later admit to playing the screw shot to save having to walk around the table).
World number one Davis needed no second invitation - clearing to reduce the deficit - and the pendulum swung his way, as he won eight of the last nine frames for glory.
Although Thorne would rise to a career-high of seventh in the world rankings at the end of the season, that would prove to be his best chance at a major title.
