Judd Trump had a routine 6-2 win over Mark King, but fellow former champion Neil Robertson was pushed all the way before beating Graeme Dott 6-5 in the UK Championship third round.
World number five Trump was not at his sharpest but was always on top against King, scoring one century and two 50s.
Robertson, the UK winner in 2013 and 2015, trailed 2-0, 3-2 and 4-3.
But his form remained strong and five breaks of more than 50 saw the Australian through to the last 16.
Scotland's Dott, the 2006 world champion, proved a typically nagging opponent.
But Cambridge-based world number 10 Robertson showed impressive battling qualities to set up a fourth-round meeting with either Mark Allen or Hossein Vafaei.
"Barring one or two unforced errors, it was a fantastic match," Robertson said. "I was really pleased with my performance and how I dug in.
"I played solid but was not at my best, but in the decider I played a killer safety shot and put the frame away."
Trump's appearance in the last 16 at the York Barbican will be his first time at that stage since he lost to Ronnie O'Sullivan in the 2014 final.
The Bristolian, a nine-time ranking event winner, plays Joe Perry in round four.
Trump said: "I missed some balls I shouldn't have missed but I am still in the tournament.

"I always felt in control and the self-belief is back. Even when I do miss easy balls I feel I can come back.
"I have worked really hard recently - probably the hardest in my career. Under pressure I feel like am confident compared to where I was a few seasons ago when I would have probably collapsed.
"I am focusing on my strengths rather than perfecting my weaknesses."
Meanwhile, Trump's close friend Jack Lisowski, the world number 17, took a big step towards Masters qualification with a 6-3 win over closest challenger Marco Fu.
Lisowski, who will play defending champion Ronnie O'Sullivan in the fourth round, raced into a 3-0 lead with breaks of 69 and 109, but said he "sort of fell over the line".
Former world champion Stuart Bingham knocked in the highest break of the tournament of 145 on his way to a hugely impressive 6-2 win over David Gilbert.
A high-quality match saw four centuries in the first four frames as Bingham took a 3-1 lead.
Bingham won the next frame, and set up a fourth-round meeting against either Sonny Akani or Jak Jones, with a break of 67.
"I expected a good match. I knew I had to be on top form and I started off like a house on fire," Bingham said.
"I am playing well and it was an unbelievable standard in the first four frames."
