Seven minutes of perfection: Thepchaiya Un-Nooh rolls in a 147 maximum break

Snooker does not get cleaner than this. Thailand's Thepchaiya Un-Nooh, one of the fastest players the game has ever seen, opened his last-32 match against three-time world champion Mark Williams at the International Championship in Nanjing with a maximum 147 break — every red, every colour, perfection — completed in just over seven minutes. It is the eighth maximum of his career, lifting him to seventh on the all-time list of 147-makers. The break was not quite enough to win the match — Williams took it 6-3 — but maximums outlive results: long after the scoreline is forgotten, a flawless 147 remains one of sport's purest sights.
