Zhou Yuelong remarkably made the second 147 of his professional career as he came from a frame down to beat Peter Lines 4-1 in Milton Keynes in the first round of the Scottish Open.
The UK Championship semi-finalist produced the magnificent maximum break in the third frame to go 2-1 up in his opening match. It was the 164th maximum in snooker history.
The Chinese 25th seed never looked back as he took the next two frames to seal his place in the second round.

Defending champion Mark Selby had a straightforward evening against Yuan Sijun, winning 4-1.
Yuan did, however, get the highest break of the match, a 122 in the fourth frame.
Mark Allen was almost perfect when it came to potting, notching three hundreds as he beat Jimmy White 4-1.
David Gilbert, who looked well off the pace, was knocked out by Matthew Stevens 4-3 in a tense, scrappy affair. Gilbert, who was 2-0 down, fought back to take his spot in the second round in the deciding seventh frame.
The first result of the Scottish Open proved to be a huge upset as Zak Surety, ranked 116 in the world, knocked out Stephen Maguire 4-1.
Yan Bingtao also fell at the first hurdle, losing 4-1 to English Open quarter-finalist Jak Jones, who made a century (109) and two half-centuries en route to a shock victory.
But the first-round match between Mark Selby and Yuan Sijun was one of a number of matches which was delayed when results of the latest round of coronavirus tests were held up. Jimmy White and Mark Allen were also amongst those waiting for the green light to play.
An epic UK Championship only finished in the early hours of Monday morning, meaning Judd Trump's first round match against Alexander Ursenbacher originally scheduled for 7pm on Monday has been moved to tomorrow.
