O'Sullivan 8-7 Bingham
Bingham shows he's still well up for the fight, a fine break of 125 sees him pull within one frame of levelling. A massive final frame of the session.
That's Bingham's 50th century at the Crucible.

Worst case he's going 8-8 into final session, but knowing Ronnie he'll definitely want to push on and possibly get to 10-6.

Not only is Ronnie the best player of all time, but he's the best player I've ever seen for pouncing on mistakes. Not letting his opponent breathe out there.
These are the moments that can be most damaging.
O'Sullivan 8-6 Bingham
Bingham looked like he was getting going, but he missed a red to middle on 28 and O'Sullivan capitalised to double his lead with a superb 84 break.
O'Sullivan 7-6 Bingham
Ken Doherty
1997 world champion on BBC Two
Before that break I think Ronnie looked very vulnerable. Stuart has had his chances to win a lot more frames than he has done.
It's kicked Ronnie into gear a little bit.

Six-time world champion on BBC Two
Ideally Ronnie would like to get a really substantial lead in these four frames after the interval.

John Parrott
1991 world champion on BBC Two
It almost looks like lift off is going to happen now.
O'Sullivan 7-6 Bingham
That's more like it from the 'Rocket', an excellent break of 79 enough to edge ahead.
Gilbert 13-8 Maguire
He's done it. Dave Gilbert is into the last four at the Crucible.
Gilbert beats Stephen Maguire 13-8 and will face either Kyren Wilson or John Higgins in the semi-finals.
O'Sullivan 6-6 Bingham

Ken Doherty

The problem was the black rocked a little bit on the spot, which means Ronnie can't pot the red. Ronnie just questioned it, which he had every right to do so.
It was a tricky situation for Ronnie and the referee.

Steve Davis
Six-time world champion on BBC Two
It was an unsettling moment. Unfortunately for Ronnie it became a problem.
He wanted to know if the ball was on the spot and whether he could get through to the red.
I think, though, the end result was that he probably couldn't pot it anyway.
O'Sullivan 6-6 Bingham
Bingham pinches the frame, this could be going all the way. O'Sullivan concedes needing one snooker.

Neil Robertson

He played safe even though he could pot the red. It's unbelievable.
This is probably one of the greatest bits of sportsmanship I have ever seen in any sport. That's incredible.
I've never seen anything like that before.
O'Sullivan 6-5 Bingham
Now then. O'Sullivan turns down a chance to pot the red as he was unsure whether the black was lying correctly on its spot.
Gilbert 12-8 Maguire
Dave Gilbert will resume after the mid-session interval, needing just one frame to reach the semi-final.
The winner will meet either Kyren Wilson or John Higgins, who resume their quarter-final tonight with Wilson 9-7 ahead.
O'Sullivan 6-5 Bingham
But he's messed it up, the break finishes on 42 after a miss on a blue to middle.
O'Sullivan 6-5 Bingham
Great chance for Bingham...he's in the balls.
O'Sullivan 6-5 Bingham
Big frame this in the context of the match, can Bingham finish all square before the mid-session interval?
