Australia's former world champion Neil Robertson was given a fright before booking his place in round four of snooker's UK Championship.
The dogged Mark King levelled the match from 2-0 down and stayed on 37-year-old Robertson's heels before he lost a tight tenth frame and the match 6-4 at the prestigious tournament in York.
Two-time champion Robertson carded a ton and four 50+ breaks in his battling win and the Melburnian admitted concentration played a key role.
"It's always tough against Mark and there was a lot of noise coming from the other table," Robertson said.
"It was tough to keep focus."
Robertson was referring to Nigel Bond's shock win over world champion Judd Trump.
Bond, who turned professional 30 years ago and was World Championship runner-up in 1995, stunned the world No.1 in round three.
The 54-year-old opened up a 5-3 lead, and then held his nerve in frame nine after a long duel on the final pink, before potting it and ending his fellow Englishman Trump's title hopes.
But 2015 world champion Stuart Bingham cruised into the last-16 with a 6-1 victory over China's Zhao Xintong.
Bingham never looked back after posting a 127 break in the opening frame, and three more half-centuries eased him past an opponent who could manage a highest break of just 60.
China's Li Hang also progressed, beating Marco Fu 6-4 in a high-quality encounter that was highlighted by the winner hitting breaks of 131 in successive frames, while Fu also posted two centuries.
