The pressure of playing world No 1 Ronnie O’Sullivan seemed to get Zhou Yuelong as he endured an embarrassing moment in their UK Championship clash.
Having eased past Matthew Stevens in the first round, O'Sullivan was again quickly into his stride at the York Barbican, winning the first frame before duly racking up a 56-0 lead in the second. But then a missed pot left his opponent weighing up six reds to aim for, and the possibility of a long plant.
A clearly anxious Zhou, who had beaten Chinese compatriot Yan Bingtao 6-5 in his previous encounter, spent almost a minute deciding how to play it. The two reds were aligned to the top jaw of the pocket, meaning a thin contact was seemingly required.
