Third time unlucky for maximum-less man Thepchaiya Un-Nooh

Thai snooker player Thepchaiya Un-Nooh suffered another maximum break nightmare during qualifying for the International Championship in Sheffield.

The 39-year-old missed the final black for a 147 for the third time in his career in the second frame of his 6-4 win over China's Lei Peifan.

Un-Nooh missed the last ball at the 2015 UK Championships and the curse struck again in a 2016 World Championship qualifier against Anthony McGill.

Un-Nooh already held an unwanted place in snooker history as the only player to have missed the black for an official 147 more than once.
