Ding Junhui has just made the eighth 147 break in the 31-year history of the UK Championship.
It was his second maximum having made one in the 2007 Wembley Masters.
It was the fourth of the season and the 67th in snooker history.
There have now been 36 televised maximums and 44 in ranking events.
Only 15 have been made by the loser of the match.
Ding's 147 came in the third frame of his last 16 clash with John Higgins, which reduced his arrears to 2-1.
He becomes the 11th player to have made more than one in competition.
