Ding Junhui has one difficult red nestled against the side cushion but moves it superbly off the green.

Brilliant shot.

Zhao Xintong gets in with an audacious double and proceeds to knock in 61 before missing a black off its spot. What a miss that is.

Ding Junhui is back at the table but it would take something special to clear up from here and snatch the frame.

At 5-0 yesterday we were thinking Kyren Wilson had no chance. He was struggling with his tip on his cue, he was all over the place.

But Mark Allen went into his shell and let Wilson come back. He's starting to play well now.

Ding of old won have won at least one of the two previous frames. He has had chances to win the last two frames and at his level you are going to get punished.

His technique is just starting to let him down under pressure these days.

Zhao Xintong wins another frame that really ought to have gone Ding Junhui's way.

The 39-year-old is oin control but when he misses a green and then also brings the black off the cushion it works to his opponent's advantage.

The world champion doesn't need asking twice and pinches the frame on the black.

Kyren Wilson halts Mark Allen's mini-revival to level this match up once more.

Wilson builds a 38-point lead, but can't bring the reds into play off potting a blue and is forced to play a safety.

Wilson returns and leaves Allen requiring multiple snookers, but Wilson produces a superb long pot on green and Allen stays in his seat.

Wilson takes the frame 65-28.

Ding snatched at that blue. That was his chance. You are going to have a lot of mini turning points but that feels like a big one because Ding had the chance to go two ahead.

Also with the way he lost it...he was short with the green and he should never have been short on the green clearing up. His cue action under pressure, we just saw him let go.

Ding Junhui comes unstuck going from green to brown. It means he's faced with a tough blue that he rattles in the jaws.

Zhao Xintong lays a snooker with his next shot and all of a sudden this see-saw frame is going back his way. Even more so when he knocks in a long blue and then clips the pink to the middle to draw level.

That feels like a big turning point.

That was world class from Ding. It is not his strength playing those shots with power.

What a pot that is. It is the best pot of the match. He was forced into it but what a shot that is.

Zhao Xintong takes a 52-point lead but can't quite get a decent run of the balls to finish this frame off.

He then misses a long red but fortuitouslyleaves the white safe. It's put Ding Junhui in all sorts of bother but he pots his way out of trouble.

He takes on a long red down the right of the table and finds the heart of the pocket. What a shot that is.

Mark Allen wins a second frame on the spin to retake the lead, and he's a bit fortunate.

Allen's break leaves Kyren Wilson in a snooker that should be easy to escape, but he hits the pink off the cushion instead of red to gift his opponent six points.

An incredible fluke sees Wilson plant one red off another and into the pocket, with the cue ball snookering Allen, but with his next shot Wilson pots the white.

Wilson trails by one point, but somehow misses a simple red and Allen goes on to take the frame 68-38.

Zhao Xintong feels aggrieved as black to the bottom right corner seems to wander off course.

It allows Ding Junhui to get set and deliver the perfect riposte, which in this case is a well crafted 80 break to go back in front.

He has the cue ball on string there. This really is wonderful snooker.

I think having won that last frame after losing six in a row, Mark Allen looks a little more confident and relaxed out there.

It is not often where the mid-session intervals come at the same time on both tables so the Crucible foyer has been heaving with people, having a walk around, heading to the bar or the loo.

A new addition to the Crucible experience this year are some of the memories from over the years for you to have a look at.

One such case has the Chinese flag Zhao Xintong wrapped around himself after winning last year's final and that is alongside a trophy Steve Davis won for his win in 1987 as well as a pair of white gloves from referee Jan Verhaas, who refereed six world finals.

Zhao Xintong started off very slow but once the second half of the season kicked in he built up a bit of steam.

He's the first player to ever win the World Grand Prix, the Players and the Tour in the same season. He destroyed the whole field at the Tour Championship in Manchester but since he has been here he has been a bit nervous. That will settle him down.

After the mid-session interval the standard will improve.

It's been absolute genius from Zhao Xintong, the first century of many I think to come in this match.

Ding Junhui miscues, gives up a free ball and suffers the most severe punishment.

Zhao Xintong never looks like missing and clears up as far as the brown to register a sublime break of 116.

Mark Allen stops the rot as he ends Kyren Wilson's winning run at six.

Off a strong break Allen pots nine balls - as many as he did in the previous six frames combined.

Allen gets a stroke of luck as Wilson misses a straightforward green, and from there he makes a break of 33.

He needs one more red to secure the frame, but the red catches the cushion and won't drop in.

Fortunately for Allen, Wilson misses a pink and the Northern Irishman is able to wrap up the frame 56-7.
