Judd Trump says he is playing "near enough faultless snooker" after making a 147 during his Northern Ireland Open second-round victory over Gao Yang.
Defending champion Trump made a maximum break in the third frame as he beat Gao 4-0 to progress in Milton Keynes.
Trump also recorded breaks of 127 and 109 to extend his quest for a third successive NI Open title.
"It's always special, even if with no crowd," said the world number one, who cleared the table in under 10 minutes.
"I was very nervous and it's exciting to make, you know that everyone is at home willing you on.
"It's special for me, it's only my fifth one I think, and whenever you make them on TV, it's always that extra bit special. It was an all-round near-perfect game for me today, I played really well."
Trump will face Belgium's Luca Brecel in the third round.
Ronnie O'Sullivan, runner-up to Trump at the NI Open in each of the last two years, will join Trump in third round after he beat Elliot Slessor 4-1.
Slessor had won his only two previous meetings with O'Sullivan, including at the 2017 NI Open.
Northern Ireland's Mark Allen, the recent winner of the Champion of Champions event, progressed to round three with a 4-2 win over Robert Milkins.
Ding Junhui, John Higgins and Kyren Wilson are among the other high-ranked players to progress but others have fallen by the wayside - Mark Selby losing 4-0 to Lukas Kleckers, Mark Williams losing 4-2 to Dominic Dale and Neil Robertson going down 4-2 to Ben Woollaston.
World Snooker has been running all of its tournaments in Milton Keynes because of the Covid-19 pandemic.
