John Higgins hoists his knee on top to the side of the table to pot a tricky yellow, smirks, then calls for the rest. Still as flexible in the mind, eh, John?

The Scotman rattles it against the pocket but Xiao Guodong is not able to capitalise. Higgins returns to leave Xiao needing snookers with the brown, blue, pink and black still in play.

Higgins nestles the brown, obscured by the blue, close to the corner pocket. Xiao ends up striking the cue ball with it with such ferocity the brown ends up flying off the table, and the man from China duly concedes the frame.

Back level.

Lei makes 48 to lead this time before missing another red down the side rail, very similar to the one that failed to drop in the first frame.

It cruelly stays over the pocket and he's soon regretting it. Zhao, after a few nibbles at the cherry, snatches the frame and leads by two.

They'll surely find more fluency later in the match, but this will do for Zhao to edge in front.

Trailing 44-33, Lei has an excellent chance to take the opening frame, but he misses the final red from close to the side rail and leaves it in the open.

Zhao capitalises and clears to the brown, which is enough.

On BBC TV, Shaun Murphy says: "That was the first frame on a plate.

"If Kyren Wilson's watching, he'll be thinking 'He didn't miss any of those against me'."

Xiao Guodong wanted to treat us to an exhibition shot at the end of the frame there! It doesn't really matter that he wasn't able to pull it off. Overall, that was not the best frame but they all count.

A relatively risk-free start to afternoon session by both John Higgins and Xiao Guodong as they look to feel themselves into the contest.

Lots of tutting and eye rolls from Higgins after a safety shot leaves Xiao a tricky long red long which he duly sinks and proves key in him banking the frame.

The 36-year-old from China pots the next two reds and almost manages a clearance during a break of 42 only to leave himself too much to do on the black.

An audacious double from Xiao on the black sees the cue ball end up in the corner pocket affording the Crucible crowd a chuckle.

We're under way again.

Four-time champion John Higgins and Xiao Guodong produced a classy session on Thursday evening that finished all square.

Similar today would set up a tantalising final nine frames on Saturday morning.

Zhao Xintong is fancied by many to have a deep run at this World Championship, but could Lei Peifan carry on where he left off against Kyren Wilson and take another major scalp?

We'll have eyes on both matches throughout the afternoon, so stand by for news, updates and expert opinion from the commentary box.

Round two is giving us plenty of excitement already, but how is your memory of round one?

It's been an incredible day for 75-year-old Brian Nicholls from Tamworth, who won £25,000 after Mark Allen's maximum 147 earlier today.

One of the event sponsors, Midnite Sports and Casino, have been running an initiative where for each session of this year's World Championship, one person in the crowd is selected at random and if a 147 happens, on either table, they win £25,000.

Lifelong snooker fan Brian, who had never been to the Crucible but had the ticket bought for him by his son as a present for his 75th birthday, has just told the media he fancied taking his family on a cruise to America next year with the winnings.

"Twenty-five grand is a lot of money, it's lovely," said Brian. "I wasn't calm, my heart was pounding. After the yellow, that was the ball where I thought 'it's on'. My son had pointed out a possible 147 with a few reds left.

"I thought he [Allen] had blown it when he got to the yellow as they are only human and can make a mistake. When that black went in, wow, lovely!

"I couldn't believe it. The Crucible is a wonderful place, I've been walking around it having a look around. I hope Mark wins his match tonight and wins the tournament - I wanted to kiss him!"

Colin from Aberdeenshire: Everyone knows about 147 breaks at snooker. Has anyone ever had a 72? 15 reds, 15 yellows and the colours?

Great question Colin, what a break that would be. The lowest-scoring total clearance we can find evidence of in professional competition is a 109 by today's 147 hero Mark Allen, at the 2016 Northern Ireland Open.

Players from eight countries have won snooker's most prestigious title and become a world champion - but China is still waiting for its first success.

Could 2025 be the year that changes?

This season's World Championship last 16 includes six Chinese players - Ding Junhui, Lei Peifan, Pang Junxu, Si Jiahui, Xiao Guodong and Zhao Xintong - with England having the next highest total with five.

"This has got to be the biggest year for China in terms of chances of having a world champion," said Jason Ferguson, chairman of the World Professional Billiards and Snooker Association (WPBSA).

"We've seen players like Lei Peifan winning ranking events and players bounce on to the scene and that could happen here. These boys have no fear and really want it.

"If a Chinese player became a world champion there's no doubt that player would become a national hero."

It was a special morning session at the Crucible as Mark Allen made that 147 - the 15th main draw maximum in the history of the World Championship.

But could the famous Sheffield theatre be replaced as the tournament's home in the near future, given the contract to keep it there expires after the 2027 event?

Matchroom Sport president and veteran promoter Barry Hearn remains a driving force behind snooker's negotiations with local authorities. He has indicated a new venue will be found elsewhere unless the tournament's long-time home is revamped or a suitably larger new home is found in the city.

The 980-seat capacity is seen as a problem, with Matchroom, which runs the snooker tour, convinced it could sell many more tickets with a bigger arena.

Hearn told 5 Live Breakfast: "It's black and white: we love the Crucible, we love Sheffield, but the Crucible and Sheffield have got to love us.

"We want to stay but the financials have to be taken into consideration. The facilities where the Crucible is are no longer fit for purpose, that's the key issue."

We've reached the end of the dramatic opening session, but there's plenty more snooker to come:

14:30

• John Higgins (3) 4-4 Xiao Guodong (14)
• Lei Peifan v Zhao Xintong

19:00

• Mark Williams (6) 4-4 Hossein Vafaei
• Mark Allen (8) 4-12 Chris Wakelin

In truth it wasn't the best of sessions between Mark Williams and Hossein Vafaei. We had some awful frames so 4-4 was a probably true reflection of things.

Mark Williams chunters away after failing to cut a tricky black into the corner pocket which leaves him needing snookers in the eighth frame.

The Welshman refuses to give up the ghost with just pink and black left in play. However, eventually Williams fouls by accidentally knocking in the black attempting to outfox Hossein Vafaei.

Both players share a knowing chuckle at the end of the frame. It will be all square when they return for the evening session.

Mark Williams knows whatever happens in the eighth he will not be behind going into the evening session so that was a key frame.

Mark Williams sees a tough pink rebound out of the pocket but it's purely academic as he nudges himself in front in clinical style, passing 100 points in a frame for the first time in the match, albeit not in one visit. The Welshman has a bit of momentum now.

Mark Williams puffs his cheeks out as he takes his seat after getting himself back on level terms by taking the sixth frame against Hossein Vafaei.

Northern Ireland's Mark Allen compiled an incredible 147 maximum break but is one frame away from being eliminated from the World Championship by Chris Wakelin following a thrilling session in their last-16 tie.

Allen was trailing 10-2 after losing all four previous frames in the morning session on Friday, went straight to the practice table in the mid-session interval and then produced snooker's moment of perfection in the first frame after the restart.

He became only the 11th player to make a 147 at the Crucible. This was the 15th maximum in the main draw stage of the tournament and the first since Mark Selby's clearance in the 2023 final.

However, world number 20 Wakelin, who beat former world champion Neil Robertson in round one, holds a 12-4 lead and only needs one more frame to move into the quarter-finals when the match resumes at 19:00 BST.

This match might turn into a classic, but it hasn't begun that way.

Vafaei battles his way back in front, sinking the pink after Williams missed following a spot of safety jousting.

One red left on the table with Mark Allen 17 points ahead but snookered. This is a massive frame. It's either going to be 12-4 or 11-5 to Chris Wakelin going into tonight's final session.
