The 'Rocket' starts in fine fashion with a wonderful 136 century break.

O'Sullivan's 207th Crucible century.

@NosdivadS: Ronnie O’Sullivan must know now that this could be the best ever chance he’ll get at an eighth world title.

Great long red from the 'Rocket'.....will the seven-time world champion show his class tonight?

Both semi-finals can be watched on BBC TV or via this page. Take your pick.

Stuart Bingham will not be overawed by this big occasion, he's not that type of player who folds easily.

And the way he came back in that second session, from 8-6 down - when we thought possibly he'd blown it - that was superb.

Stuart Bingham waves to the crowd as he enters the arena, before Ronnie O'Sullivan delights the Crucible crowd with his arrival.

John Higgins is our first player into the arena....quickly followed by opponent Kyren Wilson.

Welcome back for the conclusion of this year's quarter-finals.

What a night we have in store.

Can Ronnie O'Sullivan keep his quest alive to win a record eighth Crucible crown?

And can four-time world champion John Higgins recover from 9-7 down to beat Kyren Wilson?

Stay with us to follow all the action unfold.

What a day it's been at the Crucible....and there's plenty more action to come tonight (19:00 BST).

Ronnie O'Sullivan returns after a short break to conclude his match with Stuart Bingham, finely poised at 8-8.

And four-time world champion John Higgins resumes looking to overturn a 9-7 deficit against former Crucible finalist Karen Wilson.

See you then.

Stephen Maguire, speaking on BBC Two after his defeat to Dave Gilbert: "There was no way back after that first session, I handed the match over.

"But fair play, he played better than me and deserved it.

"I'm never going to just lie down, but it's a day and a half I'd like to forget.

"I feel like I gifted it to him - and I hate that."

Dave Gilbert fought back tears speaking to BBC Two after reaching the semi-finals: "I was struggling to even get to the qualifers to be honest. I was thinking of turning up, taking my 10 grand and going home.

"Andy Lee (fellow player and friend who has helped him) - lifesaver. I'm sorry I haven't been like this for a while. I can't wait to get out there.

"I'm feeling good. I've won a lot of scrappy games, just battling."

On possibility of facing John Higgins again after losing to him in the semi-final five years ago: "I'd love to play the great man again and see how we fare. He's a legend and I'd love to have that challenge again."

He'll be delighted he gets back into the semi-finals for the first time since he lost to John Higgins 17-16 in 2019.

Dave Gilbert withstood a fightback from Stephen Maguire to book his semi-final spot.

Gilbert had led 9-2 and was pegged back to 10-7, but kept his cool and was understandably emotional after his triumph.

Stuart's been absolutely brilliant to win in these last two frames, which he absolutely needed to do as he couldn't afford to go in 9-7 down.

All of a sudden you've got to get some food inside you now, get some energy, and then come back again (tonight).

Otherwise your concentration levels could drop.

That's an amazing turnaround from Stuart Bingham's perspective.

Ronnie didn't kill him off, but he came back so strong.

It proves how dangerous he is, he just loves playing snooker and, given the chance, he's a free-flowing player.

And he's done it, Bingham holds his nerve to leave this match on a knife-edge.

That was a wonderful break of 92 under pressure.

Advantage Bingham here...he's in on a break of 40. Just a few balls to get back on level terms.

Last frame of the session....can Bingham get all square with the 'Rocket'?

A wonderful contribution from Stuart Bingham when he needed it the most, this is turning into a real match.
