As expected, it is a full house at the Crucible and if you have got a ticket for this session then you're in for a treat.
Ronnie O'Sullivan v Pang Junxu on table one and Luca Brecel against Ding Junhui on table two.
Will the two Chinese players make superb fightbacks and get themselves back into it?
O'Sullivan 6-2 Pang
Stephen Hendry
Seven-time world champion on BBC iPlayer
It's the easy things that let you down and that's what let Pang down, especially in the first four frames. If you do the easy stuff well, you've got a chance.

MC Rob Walker has introduced the four players to the Crucible Theatre crowd and the action will be under way shortly.
There are two tables in play at this stage of the World Championship – you can watch dedicated coverage of both matches on the BBC iPlayer or via the "Watch and listen" tab at the top of this page.
Coverage on BBC Two starts at 15:00 BST.
Snooker's fabled "Class of 92" is still going strong, with two of its three most famous graduates having already booked their places in the World Championship quarter-finals.
Mark Williams, 50, will face 49-year-old John Higgins in the next round. Williams came through a tough test against Hossein Vafaei, while Higgins proved once again why he is absolute granite on a snooker table by winning a deciding frame against Xiao Guodong.
After his win, Higgins told the BBC: "It was different maybe 20-odd years ago when we were really big rivals – now we walk into the practice room and we give each other a nod as if to say: 'How are we still here competing with everybody?'
"It's incredible, and obviously you throw Ronnie into the mix as well – three special players."
Will Ronnie O'Sullivan, also aged 49, join them in the last eight?

Ronnie O'Sullivan was in superb form to complete his first-round victory over Ali Carter earlier this week. He could not quite match that display on Saturday, but 'The Rocket' still leads Pang Junxu 6-2 and is a strong favourite to reach the quarter-finals.
Is O'Sullivan your pick for the title? Or is there another player who you think will be lifting the famous trophy on 5 May?

O'Sullivan 6-2 Pang
Ronnie O'Sullivan holds a commanding lead after Saturday's first session against Chinese qualifier Pang Junxu.
The seven-time champion won the first four frames and ended 6-2 in front.
Pang had his chances, but was punished for his misses. It is a lesson he will need to have learned overnight, otherwise his hopes of a first Crucible quarter-final could be over fairly quickly.
As for O'Sullivan, he'll hope to be as close as possible to the winning post of 13 frames before Monday evening's conclusion.
Brecel 7-1 Ding
Performance of the World Championship so far? Luca Brecel was in sensational form in the first session of his second-round match against Ding Junhui.
Ding made a superb 141 break in the first frame but managed only 15 more points in the next seven as the 2023 world champion stormed into a 7-1 lead.
Brecel was simply brilliant, knocking in two centuries and four more breaks of 50 or more. No wonder Ding looked pretty non-plussed…
Murphy 3-5 TrumpMichael Emons
BBC Sport at the Crucible Theatre
World number one Judd Trump took a 5-3 lead in his World Championship last-16 tie with fellow former world champion Shaun Murphy, but narrowly missed a chance to move closer to winning a £100,000 bonus.
Trump, 35, fought back from 2-0 and 3-2 down, winning the last three frames of the session, but, when on 98 in frame eight, missed a pot on the yellow that would have given him a century break.
He has made 98 centuries this season and is the only player who could get to one hundred tons this term, something that would earn him a £100,000 prize.
Trump will have another eight frames to play later on Sunday as the match resumes at 19:00 BST, before the final session on Monday from 13:00 BST, in the best-of-25 match.
Only two players have made a hundred century breaks in one campaign – Neil Robertson in 2013-14 with 103 and Trump himself with 102 in 2019-20.
On the other table, Zhao Xintong completed victory against Lei Peifan to set up a quarter-final with fellow qualifier Chris Wakelin.
It's day nine at the 2025 World Snooker Championship and in Sunday's afternoon session we will be watching two of the game's great entertainers.
Ronnie O'Sullivan and Luca Brecel had built handsome leads by the end of the first session of their respective second-round matches – can either produce a repeat today and earn themselves a day off before a Crucible quarter-final?
Or will Chinese duo Pang Junxu and Ding Junhui find a response?
We are taking a short break on the updates for now, but will be back from about 14:15 BST to build up to Ronnie O’Sullivan against Pang Junxu (6-2) while Luca Brecel leads Ding Junhui 7-1.
Murphy 3-5 Trump
A 98 break from Judd Trump put him ahead after the morning session.
Murphy 3-4 Trump
Judd Trump hits the front for the first time thanks to a break of 62 to move 4-3 ahead in his last-16 tie with Shaun Murphy.
One frame more to go in this session.
Murphy 3-3 Trump
We're back level on table one as Judd Trump took frame six, winning it 88-6.
Trump is two century breaks away from winning £100,000 but his best break so far today is the 70 he made in frame four.
Result: Lei 10-13 ZhaoMichael Emons
BBC Sport at the Crucible Theatre
A delighted Zhao Xintong has just been speaking to the media after his 13-10 win over Lei Peifan.
"I'm so happy, that's the first time into the quarter-finals and I'm so proud of myself," he said. "In the first round he [Lei] came back against Kyren Wilson so I knew I wasn't ready to win and I needed to be strong.
"I just want to go through the Crucible and I need to try my best and enjoy it as it is very nice, the crowd is nice and I want to stay longer. This is my first time to play Chris Wakelin, I know he is really good player."
On potentially becoming world champion, he said: "It's a dream for every snooker player, if I do that I would be really happy."
On what winning the world title would do to Chinese snooker, he replied: "It would be very good for Chinese snooker. Now Chinese snooker is stronger and has a lot of young Chinese players starting."
Lei 10-13 Zhao, Trump 2-3 Murphy
Shaun Murphy has retaken the lead against Judd Trump and done so with a break of 103 in frame five.
Lei 10-13 Zhao
It is all over on table one as Zhao Xintong becomes the fourth man into the quarter-finals after beating compatriot Lei Peifan 13-10.
Lei 10-12 Zhao
One last opportunity for Lei as he comes to the table 59-25 behind. He is 34 points adrift, with 35 on the table. He needs perfection to stay in the tournament.
Lei 10-12 Zhao
Zhao Xintong is up to 41 and has a potential match-winning chance here.
Lei 10-12 Zhao (first to 13)
Zhao Xintong may just be getting a bit nervous. He was 41-12 ahead in the 20th frame and closing in on victory, only to then lose it with Lei then making breaks of 94 and 65 in the next two frames for three successive frames.
First to 13 gets through and plays Chris Wakelin in the quarter-final.
