Judd Trump remained on course to lift a third consecutive Northern Ireland Open title after beating Martin Gould to reach the quarter-finals in Milton Keynes.
The reigning champion needed a deciding frame to see off Luca Brecel earlier on Thursday. However, he enjoyed a more comfortable victory in the last 16, overcoming former German Masters champion Gould 4-1 with breaks of 103 and 76 along the way.
The world number one is joined in the quarter-finals at the Marshall Arena by the likes of Ronnie O’Sullivan and Ding Junhui.
Trump – winner of this event in 2018 and 2019 – lost his previous meeting with Gould in the European Masters semi-finals in September.
But he drew first blood on the brown in a lengthy opening frame, although world number 34 Gould levelled on the colours.
Despite being forced to a re-spotted black in frame three after rattling it in the jaws of the corner pocket, Trump held his nerve to move back in front before reeling off breaks of 103 and 76 to advance.
His quarter-final opponent will be Scott Donaldson, who knocked out high-flying Mark Allen before seeing off Noppon Saengkham in the last 16.
Elsewhere, O’Sullivan overcame stomach problems to book his place in the last eight.
The Rocket appeared to be physically struggling on Thursday – notably breaking wind during his 4-2 victory over former UK champion Matthew Stevens much to the amusement of referee Ben Williams.
Locked at 2-2 with Thepchaiya Un-Nooh later on, O’Sullivan produced a nerveless 70 clearance to steal frame five on the black before a run of 52 in the next saw him over the line.
In the quarter-finals, the six-time World champion will face Ding, who dropped just a single frame all day as he swept aside Yuan SiJun and John Higgins.
Elsewhere, former UK semi-finalist David Grace produced an amazing fightback from 3-0 down to stun Michael Holt 4-3 to set up a last-eight date with China’s Yan Bingtao, who edged out compatriot Zhao Xintong by the same scoreline.
Two-time Crucible runner-up Ali Carter also advanced to the quarter-finals; making breaks of 103 and 101 in his 4-2 success over Ben Woollaston.
The Captain will face Kurt Maflin, who recorded a pair of 4-1 wins over Ryan Day and Igor Figueiredo.
