1. World Snooker Championship LIVE: Scores and latest updates as Judd Trump and Ronnie O’Sullivan in quarter-final action

Trump could do with winning this frame quickly and making a nice, confidence-building break. He’s having to move the cueball up to the baulk end for the moment but pots the blue into the green pocket to get it back on its spot.

Lands awkwardly on the next red though… The run of the balls not going for him at the moment. Has to play safe off a red after a break of 11 – he leads 34-0 but Jones has a look at a long red. He misses the pot and the red cannons the pink back into play. Trump has a tricky cut on a red to get back in and he makes it. Another chance for the 2019 champion.

The high value colours weren’t well placed and Trump eventually runs too far out of position on 23, so tucks in behind the yellow. He was a bit unlucky that the pack didn’t split better.

But Jones is too pacey with the roll-up into the reds and Trump is back in with a red to the right corner.

Big shot for Trump as he decides to crash into the main pack of reds off the blue when moving the break to 17. Connects well but a bit unlucky as he’s only left with a thin cut on a red into the left middle pocket. He makes it! Great pot and cannons into the blue which stops the cueball running too far away, so he’s on the brown.

The break moves beyond 20 although blue is now off its spot and the pink and black are tied up.

Right, both players left the arena for a quick break after that last frame and I’m not surprised. 90-odd minutes for two frames, let’s hope they start speeding things along slightly…

That’s better from Trump! Pulls out a stunning long red and follows it up with the green. Black is out of commission and when he plays the pink, it too is spotted somewhere it can’t be potted so he’ll be using the blue for now.

Jones digs out a nice pot on the yellow and then tidies up green and brown as well. Misses the long blue but Trump has no interest in playing on for snookers.

A marathon, 55-minute frame but Jones comes out on top and now leads 6-4. That’s a huge blow for Trump.

Four more penalty points to Jones and then finally he pots the red! Great bit of cueing from mid-range going around the brown.

Then pots brown to middle and just needs a mid-range yellow followed by green and brown to leave Trump needing a snooker…

Still fighting away on this final red – whoever pots it will likely go on to win the frame. Jones has a go into the green pocket but misses.

Trump then put in a snooker and he gives away 12 points as Jones goes back ahead 53-46 but when he does hit it, he puts his opponent back in a snooker. This is pretty compelling stuff if you’re a fan of safety play.

Four more penalty points from a similar position for Trump and every time Jones comes to the table now, he’s in a snooker. We pass the 40-minute mark in this frame. Trump leads 46-41

Jones gives away four penalty points when he hits the brown while trying to swerve to hit the red and Trump then puts him in another devilish snooker but he does brilliantly to come off the top cushion and connect with the red.

Trump definitely on top in this safety exchange though and earns another four points from a snooker when Jones comes up short. Trump now leads 42-41.

It’s been much more free-flowing stuff on the other table and Stephan Maguire has made a century to win just his third frame of the match as he trails 9-3 at the mid-session interval.

Dave Gilbert will need to win all the remaining four frames after the interval to win with a session to spare.
