Ronnie O'Sullivan will go down as one of the greatest stars to ever grace the snooker table - and 'The Rocket' has produced yet another moment of brilliance to add to his collection.
The 47-year-old is the current world number one, having won the World Championship a record seven times.
He is currently in action at the UK Championship, which he has also won seven times, and has been in the quarter-finals of the York event.
O'Sullivan ended up beating China's Zhou Yuelong 6-5, but the world number one did not have things all his own way in the contest.

O'Sullivan had been leading 4-1, but then Yuelong fired back to lead 5-4 and it looked like the Briton was poised for a shock exit, having been sitting in a commanding position.
But O'Sullivan rallied to win the final two frames and clinch a 6-5 victory and book a place in the semi-finals and avoiding exiting the competition after being so close to what looked to be a straightforward victory.
The Rocket admitted after the encounter that he was "embarrassed at times" in the match and was "all over the gaff" as he reflected on his victory.
Speaking to BBC Sport, O'Sullivan said: "I felt a bit embarrassed at times - it was just desperation I started to play all right.
"I was just going through the motions and plodding away. I was just so frustrated with how poorly I played, there really was no pressure on me.
"I was awful. Technically I'm all over the gaff."
Despite that, O'Sullivan did managed to pull off quite a shot in the fourth set which underlines his enduring quality and clash.
O'Sullivan potted the brown ball in the top left hand corner from an extreme angle, with the white rebounding off both cushions, jumping in the middle of the table, before eventually coming to a halt at the bottom end.
In so doing, O'Sullivan was then in a great position to continue and back with a couple of red balls to remain at the table.
Watch it for yourself below - it just goes to show that though form can be temporary, class in indeed permanent.
