We're back for the concluding session. Who will prevail?

Kyren has found his form at a vital stage. He doesn't really want an interval - he wants to stay out there.

John Higgins battled back but he has no elbow room now. Kyren Wilson just needs one more.

Can you chalk your cue in a confident manner?

Kyren Wilson appears to do so. He's radiating confidence,

And why wouldn't he be? He's now just one frame away from the semi-finals as they go to the mid-session interval after a brilliant 108 clearance.

Remember (how could you forget?) that Ronnie O'Sullivan is going for a record eighth world championship crown in the modern era.

It would be a 42nd ranking title. Remarkable.

John Higgins has fought very hard in this game but it is slipping away from him.

That was a brilliant brown from Ronnie O'Sullivan to dig himself out of a hole.

He'll breathe a sigh of relief in his dressing room.

But O'Sullivan has pinched it in dramatic style, potting the brown and blue to leave it all square again.

What a gripping frame. O'Sullivan just needed the yellow to win, but missed a pot to a middle pocket.

Bingham needs all the colours for a re-spotted black.

Kyren Wilson is clear favourite to progress now.

He's looking relaxed and focused at 11-8 ahead against John Higgins.

David Gilbert was absolutely beaming as you might imagine in his post-match press conference a little earlier.

The Englishman is back at the single table set-up, with his only previous appearance in the last four at the Crucible coming back in 2019, the same year he hit a career-high ranking of 10th in the world.

He has slipped down them in recent times to sit 31st but has so far looked like one of the form players of the World Championship.

“It was an impossible thought not too long ago but I’m in the semis and feeling great," Gilbert said.

"It is a massive achievement. Only five weeks or so I couldn’t be bothered to play in the qualifiers, I thought 'just turn up take the £10,000 and that’ll be that'.

"I have a lot of confidence in myself and am motivated to prove to myself that I can go out and play.

"I miss being a top 16 player. I have had times in my career where I have pressed the self destruct button. But the motivation is back now. If I am sitting here on Monday night with the trophy, no one could be more proud."

Kyren Wilson was a beaten finalist in 2020 and he wants to go one better this time.

He looks in good shape and takes the second frame of the evening to move three frames from victory against John Higgins.

The winner will face David Gilbert in the semi-finals.

Stuart Bingham fancies the job. He's started to realise he can win it.

He's growing in confidence and he's relaxed.

O'Sullivan had a chance to edge ahead, but broke down on a break of 39.....and Bingham has showed nerves of steel to pinch that frame for a well-deserved lead with a run of 67.

Stuart Bingham is not going away. He is looking calm and composed and exuding confidence which not every player is capable of when they face Ronnie O'Sullivan.

Stuart was asked the question - and he answered it. He just loves snooker.

Stuart Bingham will just not budge, this one looks like it's going the distance.

The 2015 world champion responds with a break of 63 to level matters.

There's one reason John Higgins is a four-time world champion.

He knows how to dig in.

The Scot takes the opening frame of the evening and trails Kyren Wilson by one.

Ronnie's job is to keep Stuart in his chair for as long as possible.

Stuart has just got to try and force his way into the match, he's got to be patient.

But sometimes against Ronnie O'Sullivan you never see a ball.
