Thepchaiya Un-Nooh Fires 147 Maximum Break Against Mark Williams
Thai snooker player Thepchaiya Un-Nooh compiled his eighth career 147 break during a round-of-32 match against Mark Williams at the 2026 International Championship in Nanjing on Monday, snookerhq.com reported.
Climbing the All-Time Maximum List
Un-Nooh manufactured the maximum break in the opening frame of the contest at the SNC National Fitness Center. Getting in early with a red to the middle, he maintained position throughout the clearance, pausing briefly only to double the 14th and penultimate red before cleaning up the remaining colors.
The maximum break is the 247th in professional snooker history and moves Un-Nooh into seventh place on the all-time list with eight 147s, breaking a tie with Ding Junhui. Ronnie O’Sullivan leads the historical standings with 172 maximums, followed by John Higgins with 133, Stephen Hendry with 114, Shaun Murphy with 10=5, Stuart Bingham with 9=5, and Judd Trump with 97.
Un-Nooh’s previous maximum came in March during the World Open final in Yushan, where he constructed a 147 on his way to defeating Ronnie O’Sullivan for the title. Despite the milestone in Nanjing, Un-Nooh could not secure the match victory against Williams, falling by a 6-3 margin.
Un-Nooh Claims High Break Bonus as Tournament Progresses
While the International Championship does not offer a dedicated tournament prize specifically for a maximum break, Un-Nooh is positioned to collect a £5,000 high break bonus. Williams advanced to the last 16 of the tournament, continuing a run that recently included a final appearance at the English Open and a semi-final finish at the Northern Ireland Open. The overall winner of the event will claim a £175,000 champion’s cheque when the final concludes on Saturday.
