Trump 12-9 Murphy
It could have been a 134 for Shaun Murphy, but he missed the brown.
However, still a fantastic frame-winning visit of 112 and a third frame on the spin for the Magician. Can he conjure up one of the greatest of all snooker great escapes?
Trump 12-8 Murphy
Ken Doherty
1997 world champion on BBC Two
Judd, if he wasn't worried before, will start to be getting a bit worried now.

Shaun Murphy will get a mammoth £147,000 if he is to make a maximum 147 in this tournament.
Any player who does it twice in the UK Championship, Masters, Saudi Masters and World Championship this season will get a £147,000 bonus.
Murphy made a 147 break in his Masters semi-final win over Mark Allen back in January so another moment of perfection would be very profitable.
Judd Trump yesterday collected a £100,000 bonus when he reached the 100-century mark for the season.
Si 10-10 Woollaston
Steve Davis
Six-time world champion on BBC Two
Si Jiahui's body language is not good.
He should just play the balls not the player.
Trump 12-8 Murphy
Shaun Murphy doing exactly what the BBC Two pundits have said, so far.
He's carried on where he left off before the interval, a wonderful break into the 60s and counting...
Trump 12-8 Murphy
Stephen Hendry
Seven-time world champion on BBC Two
Don't make any unforced errors, don't miss anything easy and then you've got a chance of at least prolonging the match.
And maybe of doing something special.
Trump 12-8 Murphy
John Parrott
1991 world champion on BBC Two
Shaun has to play every frame as if it's the final one and give everything he's got.
Meanwhile, the players are back out on table two...

It's all square again going into the interval as Ben Woollaston wins his third of four frames this afternoon.
Hard to predict a winner here.

Paul Curran: What a quarter final we could be in for, Trump v Brecel, not much safety there you would think.
Trump 12-8 Murphy
Stephen Hendry
Seven-time world champion on BBC Two
This interval is coming at a good time for Judd. He can forget about it and come back fresh and probably win the match in the next frame.
If they had kept going without an interval, Shaun was starting to get a bit of momentum there and it might have been a different outcome.
Trump 12-8 Murphy
Image source, Getty ImagesThe break ends on 72 but Judd Trump misses a tricky black and concedes shortly after.
Still life in Shaun Murphy yet as the players head backstage for the interval. Judd Trump, though, only needs one more frame to reach the quarter-finals.
Si 10-9 Woollaston
There's been a sense all along that this match might go all the way, and nothing that's happened today has changed that.
Si Jiahui edges back in front, and it's a big frame next before the mid-session interval.
Trump 12-7 Murphy
Ken Doherty
1997 world champion on BBC Two
There are a few matches here that have been turned around from a 12-8 scoreline and Shaun is certainly giving himself a chance.
He's past the snookers required stage in this frame...
Trump 12-7 Murphy
Huge chance for Shaun Murphy to take this match to at least the final mini-session.
Bit of a fortunate - I'm almost certain unintended - four-ball plant gets him in, and the reds are spread beautifully. He'll expect to win the frame from here.
Trump 12-7 Murphy
Dennis Taylor
1985 world champion on BBC Two
He is the sort of player, Shaun, who, if he gets on a roll, can knock three or four frames together in very little time.
Trump 12-7 Murphy
Real look of focus and concentration on Shaun Murphy's face here.
He's taken these balls nicely and reduces his deficit with an admirably cool and composed 88 break.
Murphy halts Judd Trump's five-frame burst from 7-6 and he's still in this - just.

Managed to tune into the snooker over lunch and just saw that break from Judd to go 12-6 up. Every shot was so controlled and smooth it almost looked like slow motion. He's a cut above most players for me and it's a crime he only has one World Championship - hopefully this year is number two of many more.
Tim
Trump 12-6 Murphy
Shaun Murphy trudges back to his seat thinking he might have played his last shot in this year's World Championship after missing a tough red with the cue ball tight on the cushion.
But a surprising miss to middle by Judd Trump grants the Magician a lifeline...

There are another six main events in the UK this year with tickets on sale for them already.
The next main domestic tournaments are...
