Ali Carter reached his first World Championship semi-final with a 13-9 victory over 2002 champion Peter Ebdon at The Crucible.
The 28-year-old carried a 9-7 overnight lead, which included his historic 147, and eased through Wednesday's final session to wrap up a 13-9 triumph.
A break of 59 gave Ebdon the first frame but Carter hit back by winning four of the next five to prevail.
He will now face either Stephen Maguire or Joe Perry for a place in the final.
Carter never threatened a repeat of his heroics from Tuesday evening - making no breaks of 50 or more in the scrappy four frames captured subsequently - yet his passage to the last four rarely looked in doubt.
606: DEBATECarter admitted he had only managed a few hours' sleep following his magnificent 147 but said: "I don't need any, I'm pumped up on adrenalin.
"I watched the break again on TV last night, I was keen to see the celebration because I was quite pleased to say the least.
"It was always going to be a tough battle today after achieving that yesterday. The main objective was to win the match, you don't want to make a maximum and lose because that would take the shine off it."
A magnanimous Ebdon said: "The better man won on the day. There were three or four occasions when I should have cleared up to win frames but all credit to Ali, he put me under a lot of pressure and was a worthy winner.
"The 147 was a fantastic break and I was absolutely thrilled for him. He is a really nice guy and one of the players I go out to dinner with and share a bottle of red.
"I didn't play up to my capabilities so I'm going to have to work hard and come back next year because I'm determined to win this again."
