Mark Selby fended off a charge from Ronnie O'Sullivan to land his second Betway UK Championship title and shred any remaining doubts about his credibility as snooker's world number one.
In a match that peaked with a jaw-dropping stretch of play in the evening session that included three consecutive total clearances, Selby emerged a 10-7 winner.
As he lifted the trophy at the York Barbican, the 33-year-old from Leicester became the sixth player in the sport's history to secure the World Championship and UK titles in the same calendar year.
He joins illustrious company there in O'Sullivan, Stephen Hendry, Steve Davis, John Parrott and John Higgins, and as champion collects £170,000.
Come the end of the match there was no doubting Selby's relief, having seen a 7-2 lead slashed to 8-7 by a spell of vintage O'Sullivan break-building.
The five-time UK champion ploughed in breaks of 56, 80, 134, 130 and 82 to ask the question of Selby, but the challenge drew a rousing response.
O'Sullivan's two centuries in that streak had come either side of a 137 from Selby, with all three being total clearances.
The next ton came from Selby though, speaking volumes of his temperament as he made 134 to power one frame away from the winning line.
And after a cagey start to the next, Selby slotted a long red to set up a match-clinching 107, pointing to wife Vikki in the crowd as he sank the ball that made sure of another major piece of silverware.
Selby added: "He put me under pressure, asked the questions and I was really pleased with how I held up at the end.
"I tried to stay in the moment, not get too far ahead of myself."
O'Sullivan was hailed as "the best player in the world by far" earlier in the week by former UK champion Matthew Stevens, but Selby now has ample evidence to pick apart that argument.
A 95th consecutive week at number one begins for Selby on Monday, and this was his 10th ranking title. He is almost certain to remain at the top through to the World Championship in April, even if he fails to win another match before then.
Victory also meant he is now a multiple winner of all three of snooker's Triple Crown events - after two Crucible triumphs and three Masters successes.
"To win the three majors is a great feeling but to do it twice is even better," Selby said. "If I never won another tournament I'd be happy with my achievements."
O'Sullivan said: "It's a fantastic night for him.
"I scored all right but I missed too many easy balls.
"I think I did all right considering he's world number one and so far ahead of everyone else."
While it was far from pleasant to be outmanoeuvred by the man he described in a 2013 memoir as 'The Torturer', O'Sullivan knew what was coming.
Damien Hirst, the Britart multi-millionaire and friend of O'Sullivan, arrived after the third frame of the afternoon.
But Hirst, who has watched many of O'Sullivan's greatest wins, this time had to sit and suffer with fellow supporters of the 'Rocket'.
Selby promised to celebrate long into the night, just as he did on landing his first UK title four years ago.
"I'm having flashbacks to 2012," Selby said. "I strolled out of the after-party at 7.30 in the morning, went back to the hotel and went and had breakfast with nine or 10 other families, then went back to the room to get two hours' sleep.
"I woke up at 10 o'clock and thought 'I'll go down for some breakfast', and the woman in the dining room told me I'd already been down and I didn't believe her. It may be similar tonight."
