The word 'risk' does not feature in Wu's dictionary.

He does not mind going for his shots and it is refreshing to see because he never fears what he may leave if he misses - he is always looking to win.

Neil Robertson can't make the first century of this quarter-final, but a break of 70 is enough to restore his one-frame advantage.

Neil made a 77 break to win the second frame but this has been the best break he's made so far.

The reds weren't easy but the cue ball has been better in this visit and it was a great plant to start the break off.

For the second frame in succession, a Wu Yize visit breaks down on 56.

It doesn't matter - Hossein Vafaei misses a mid-distance red and Wu pulls out a fantastic plant to the bottom left corner to get back in.

There was a fair bit of space between those reds and they were not lined up with the pocket at all. He's made that plant, as they say - and how.

That helps him add another 52 to the earlier 56 - and Hossein Vafaei looks a slightly worried man in his chair. Two frames of the session to go.

Neil Robertson has picked off the loose reds to move into a 22-point lead with 59 remaining.

There's at least one more available red, but two of the other three are blocking each other and the third is close to the corner but tight on the side cushion.

Still work to do for the Australian.

John Higgins leaves a red over the corner pocket for Neil Robertson. The only trouble for Neil is that there's another red in the way.

No bother, though - he plants the first red onto the second from long distance to start another break.

"That was anything but easy, it had to be so precise," says Joe Perry in the commentary box.

Signs that Wu is beginning to really feel at home.

Hossein Vafaei's poor break-off shot leaves him a chance of a red to middle which he gobbles up.

The next shot is key though - a superb positional shot off the green to get on the red nearest the black. In goes that red and Mark Selby's conqueror has a chance to build a healthy lead in frame six.

John Higgins has now made six unforced errors in this opening session. It feels a little like after the Lord Mayor's show at present but it's just whether Neil Robertson can punish him.

Neither player has hit the heights so far.

Neil Robertson couldn't make the most of his opportunity after that John Higgins miss, adding just eight points, and we might be in for another one of those scrappy frames now that Higgins has sent a red up into the baulk end.

Wu Yize's break ended on 56 as an attempt to split the remaining reds was not met with any fortune.

Hossein Vafaei made a decent fist of trying to get back into the frame but a lot of the reds were awkwardly placed and there was just too much to do.

In the end, he pushes the boat out on a doubled red to middle, knuckles it and the red goes up near the top corner, leaving Wu a gimme and he mops the remaining required balls up nicely until missing an exhibition pot on the blue. Frame long over by then.

John Higgins doesn't add too many more... he gets the wrong side of the blue and that eventually proves costly, with the next red from mid-distance staying up.

An easy starter left for Neil Robertson, too.

An anxious look towards the middle pocket from John Higgins as a dead-weight pink only just drops in, via a nudge off the near jaw.

The Scot is on a break of 20 with plenty of open reds to go at.

It's amazing to think that the greats of our game have probably forgotten more than Wu Yize knows yet - but he's already playing at this level.

Not just competing but challenging for titles, big titles. He won one earlier this season (the International Championship in China, beating John Higgins in the final).

In five to 10 years, it's amazing to think where this player will be, he's got the world at his feet.

The 22-year-old Chinese star has started the second mini-session the way he left off the first, looking in fine fettle and has already built a 50-odd point lead...

No two frames are ever the same, but in that little mini-session, apart from one of the frames, the balls just got a bit awkward. Some of the safety was played at the top end of the table and that doesn't always make for free-flowing games.

Hopefully this mini-session will be a little different and both players are settled in.

Reigning world champion Zhao Xintong let a 3-0 lead slip as Shaun Murphy fought back to claim a 5-3 lead in the opening session of their World Championship quarter-final.

Zhao, 29, has openly talked about the pressure of defending his crown and lifting the 'Crucible curse' that has followed first-time winners at the famous Sheffield venue, but began in scintillating fashion.

A break of 122 suggested Zhao had picked up from where he left off against Ding Junhui in the second round, and when he pinched the second frame and made a half century in the third, he had established a healthy advantage.

But Murphy, who won the title in 2005, crafted a 69 then reeled off the next four frames to turn the match on its head.

Over on the other side of the auditorium, Barry Hawkins shared the opening six frames of a high-quality contest with Northern Ireland's Mark Allen.

However, Hawkins, who had already compiled a century break and three other half centuries, knocked in breaks of 75 and 63 to open up a deserved 5-3 scoreline in his favour.

Both matches resume at 19:00 BST.

Still plenty of action to come this afternoon, of course, but from 19:00 BST the final session of the day will get under way.

Shaun Murphy and Barry Hawkins will begin with 5-3 leads against Zhao Xintong and Mark Allen respectively.

There will be live TV and text coverage of that session on this page later on.

I think 2-2 is a true reflection of the match. They've been very even. This one could go very close.

Like on the other side of the curtain, John Higgins and Neil Robertson head to the mid-session interval level at 2-2.

A break of 56 gets Higgins over the line in frame four.

John Higgins is put back in by Neil Robertson, having potted the pink when playing safe off a red.

With the cue ball tight to the top cushion, he attempts to screw back to a similar position off the pack and flukes a red into the middle.

Higgins then tries a cut-back black - and gets it! Great shot.

And the reds are scattered all over the place - a good chance to level the match before the interval.

A beautifully put-together 90 break with some fine positional play brings Wu Yize level at 2-2 at the interval.

A lovely collection of cute cannons, powerful pots and pinpoint positioning.

It draws much admiration from Ken Doherty in the commentators' box.

Only shame is that the final red along the cushion rattles the jaws - no century but the number 10 seed is back level as both players head out for their mid-session interval.
