Judd Trump produced a great escape to keep alive his hopes of a first Betfred World Championship title.
At the tournament he regards as being "10 times bigger" than any other, Trump was in deep first-round trouble when he dropped the opening frame of the day to slide 7-3 behind against Liang Wenbo.
The 26-year-old had been off his game on Wednesday and it called for a champion's response to clamber out of danger.
Trump, who reached the 2011 Crucible final and was a semi-finalist last year, was up to the challenge and took seven of the next eight frames to win 10-8.
His victory tees up a tantalising second-round clash with Wenbo's fellow Chinese player Ding Junhui. Trump admitted it was going against him at 7-3, but he was heartened by edging the next frame, and said: "Then I got some momentum and played some really good stuff.
"I took the balls really well, felt very confident, very relaxed under pressure. It seemed like when I had my back against the wall that's when I thrived.
"I played some real good snooker, just solid snooker. I wasn't forcing it really.
"I took a bit of heart from when I was losing big to Shaun Murphy a few years ago and came back to win that."
On the other table, Hong Kong's Marco Fu edged 5-3 ahead of Scotland's Anthony McGill as they began their best-of-25-frame second-round match.
