Judd Trump says he will have to improve significantly to stand any chance of winning his second UK Championship.
The 2011 UK champion thrashed Jamie Jones 6-0 to secure a quarter-final place in York.
Breaks of 100, 59, 51 and 47 saw the world number two dominate to reach only his second UK quarter-final since 2014.
"It's going to get a lot harder than that. I know if I perform like that against one of the top, top players, then I'll be going home," he said.
"It [the scoreline] was a bit flattering. He didn't really turn up. When someone misses chances against you it's important to punish them - and that's what I did.
"I don't know whether it was a just a bad day at the office for him, but I'm sure he'll be disappointed with how he played."Ronnie O'Sullivan says he was asked to 'consider future'Watch on iPlayer: Amol Rajan Interviews - Ronnie O'SullivanUK Snooker Championship 2023: Match schedule, results, BBC coverage and format
Trump opened with a fine century break before Welshman Jones missed chances to level, allowing his opponent to cruise into a 4-0 interval lead.
It was also one-way traffic following the resumption as Trump claimed the two frames he needed for a routine victory and a meeting with either Mark Selby, a two-time UK champion, or Barry Hawkins on Friday.
"It was a nightmare, I didn't enjoy that at all," Jones told the BBC.
"I didn't settle down and the match got away from me. I think I tried too hard."
Meanwhile, three-time UK winner Ding Junhui beat Tom Ford 6-3 to guarantee a quarter-final berth.
China's Ding led 2-0 thanks to successive century breaks - 126 and 110 - before Ford responded with runs of 118 and 98 to restore parity.
But Ding pulled away with further breaks of 106, 51 and 48 to set up a meeting with either double UK winner Mark Williams or qualifier Jamie Clarke, also on Friday.
