Ronnie is actually playing with a different cue today. He likes the tip on this one. If he gets through he is going to swap back and put a new tip on that one.

Ronnie is still the only player who can opt out of so many tournaments and dial himself in for particular events.

You would not put it past him to pull another rabbit out of the hat even though it is getting harder for him.

The acid test will be when someone starts to play really well against Ronnie.

In the penultimate match of the first round, Si Jiahui of China takes on Iran's Hossein Vafaei.

World number 15 Si reached the semi-finals in 2023, but the 23-year-old is looking for his first career ranking title.

Vafaei, 32, beat Chinese practice partner Gao Yang 10-4 in the final round of qualifying last week to secure a place at the Crucible for a fifth successive season.

The world number 32 reached the last 16 of the World Championship in 2023 and 2025.

World number one Judd Trump awaits the winner of this one.

Ronnie pulled off some wonderful long pots [in the first session] which has been his Achilles heel over the last couple of seasons. He has not been up there with the best in the world in that department but that was tidied up a lot.

He wanted to get the job done early and was right on it.

Ronnie O'Sullivan dominated the opening session of this match on Tuesday.

Ronnie O'Sullivan heads into the concluding session of his first-round match with He Guoqiang with a commanding 7-2 lead.

O'Sullivan, 50, is chasing a record eighth world title in the modern era and it would be a huge surprise if he was not to advance to a meeting against fellow 'Class of 92' great John Higgins.

Four-time winner Mark Selby only needs three more frames to move into the last 16 of he World Championship after he dominated the opening session against Wales' Jak Jones.

Selby, 42, has lost in round one at the Crucible in both the past two years, but stormed into a 6-0 lead over the 2024 runner-up, helped by breaks of 67 and 50.

Jones took a tight seventh frame, before Selby instantly regained his six-frame advantage thanks to a break of 78, although Jones ended well with a 90 break in the final frame of the session.

Selby leads 7-2 and their match will be played to a finish in the evening session, which begins at 19:00 BST.

Seventh seed Selby will aim to continue a remarkable run of results for the seeded players, with all 12 to have finished their matches to have won.

The World Championship has been played at the Crucible in Sheffield since 1977 but never before have all 16 seeded players advanced into the second phase.

Fifteen, set in 1983 and then matched in 1993, is the current record and if Selby, Ronnie O'Sullivan, Si Jiahui and Neil Robertson all gain victories then all 16 of the qualifiers would have been eliminated in round one.

Not long now until the action gets back under way. You can stay across it all on BBC Two.

Jak Jones is letting his cue arm go in the last frame of this session and is playing beautifully.

Where was this earlier?

The Welshman gets a huge slice of luck on 51 with a red that hits both knuckles of the left middle before wandering into the top right corner. It allows him to go on to make 90 before missing a black to the corner.

Has Jones given himself a route back into this match? He'll still be a long way back heading into this evening's concluding session.

Mark Selby looks determined to not let Jak Jones off the hook.

He has a laser-focused look about him as he gets in amongst the balls and takes another frame with a break of 78, his highest of the match so far.

It looks like we'll have time for a ninth frame.

Jak Jones gets a frame on the board to a huge cheer from the crowd.

That looked like another frame that was going to go Mark Selby's way but the Welshman constructs a break of 34 to finally get over the line in own.

Four debutants were making their first appearances at the Crucible and three of them are now out with the fourth very likely to join them heading for the exit door later today.

Antoni Kowalski, the 22-year-old who was the first from Poland to qualify for the finals, lost 10-4 to Mark Williams on Sunday.

English teenager Stan Moody, 19, lost 10-7 to Kyren Wilson the next day and now another Yorkshireman, 20-year-old Liam Pullen, is out after that 10-6 loss to Chris Wakelin.

The only debutant left is China's He Guoqiang but it will be the story of the tournament if he can recover from 7-2 down against Ronnie O'Sullivan.

That's 12 out of 12 seeds through. We just need O'Sullivan, Mark Selby, Si Jiahui and Neil Robertson to complete the set and make a bit of Crucible history of all 16 seeds progressing.

The partition has gones albeit Jak Jones may wish it hadn't.

Mark Selby rattles off another frame by potting a long yellow and putting the Welshman, who needs snookers, in one himself.

Jak Jones is well and truly having one. He goes in off while playing safe on the yellow and now finds himself snookered behind the black while 25 points down.

The Welshman brilliantly gets out of that but Selby is still in charge of this tactical exchange.

There are 27 points remaining.

Chris Wakelin pulls out a cross double.

Brilliant from the world number 13, who then polishes off a few more balls to give himself an unassailable advantage and a very good first-round victory.

He's just had too much nous for the 20-year-old debutant.

That's every single seed through so far.

Jak Jones gets himself back into the sixth frame before running out of position.

He then ends up snookered on the final red and gives up a free ball. Selby knocks in the brown but then misses a pink while playing with loads of right-hand side.

Jones rolls in a straightforward red but flunks the black off its spot. Wow.

Liam Pullen has clearly decided it's all out attack from here.

But then he rattles the jaws with a red to the bottom left corner it stays out and tracks across the table to end up giving Chris Wakelin a look at a pot into the opposite side.

Wakelin enjoys a run of 62 before failing to drop in a black off its spot. That would have been the match.
