Neil Robertson is one frame away from securing his place in the second round.

The world number three swerves around the blue brilliantly to land a long pot on red, but is unfortunate that the cue ball leves nothing open.

It matters not - he builds a break of 80 to win the frame 84-4.

Mark Allen looked set for a 147, but he wanted that frame, he wasn't going to push the boat out.

And he'll be picking up on the body language of his opponent. He wants to grind him into the ground, doesn't want to give him an inch or give him any sort of confidence.

Mark Allen wins a fourth frame in a row to stun Kyren Wilson.

Allen looked to be on for a 147, but in the end misses a simple red and settles for a break of 78.

Wilson didn't leave his seat - he has got some serious work to do.

This is the cue Kyren Wilson won the Masters with. He has had enough time in between sessions to change the tip if he didn't like it.

It's cruel to say, but he's only really got himslf to blame. You can't blame your equipment, you should be ready to play when you come to the World Championship.

If he didn't like his tip when he won the Masters then he should have changed it.

This is getting a bit ugly for Kyren Wilson.

After a tight opening, Mark Allen compiles a half-century break to take full control of this match.

Wilson looks downbeat, and understandably so.

After a slow start to the frame saw both players foul, Neil Robertson break for 80, his second best of this match, to win the thirteenth frame 84-4.

The Australian needs two frames after the interval to snatch the final place in the second round.

Against an opponent who is a bit reluctant, Neil Robertson has stayed true to his game plan to pot the balls and play attacking.

Neil Robertson puts daylight between himself and Pang Junxu by winning the twelfth frame 78-6.

The 2010 winner looks to have this one back under control with one frame to go until the mid-session interval.

Kyren Wilson had two or three chances in the first frame, another great chance there. He's just not scoring enough, like the way he was scoring during the Masters.

He looks like he is struggling - he's lacking confidence, his cue ball is not as tight as it should be.

That all derives from not being completely content with your equipment. If you're banging the tip on the floor when your opponent has just gone out, it doesn't give good signals.

It's very worrying times already, he looks totally out of sorts. He needs a good frame in one visit to get back on the horse.

Kyren Wilson looks to have lost the cue ball, but he edges the black in beautifully on his way to constructing break of 46.

But that's not enough to keep Mark Allen at bay, as he breaks for 46 to win the frame 64-46.

Wilson is making a fair few mistakes here, he doesn't look comfortable.

He's become the ultimate percentage player, Mark Allen. He doesn't take many risks, that's why he is so tough to beat.

Very edgy, both of them were feeling the nerves. Glaring missed pots. It's understandable, it's a big match for both of them, a lot at stake, but these are two serious campaigners.

Kyren Wilson spoke about his cue, he's not happy with it.

The pink he played - he was supposed to be hitting it side-to-side, but hit it full on and left it open for Mark Allen.

If he's having problems with his cue on a simple shot like that, it doesn't bare well for the rest of the match.

Neil Robertson works hard to construct a break of 77, before Pang Junxu opts to play on despite trailing by 73.

Robertson looks a bit confused, bu he returns to the table and takes the frame 88-28 to reclaim the lead in this match.

Mark Allen edges a tactical opening frame 62-53.

Wilson leads by 52, but pots the cue ball and Allen cuts the deficit to 12 before plying a safety on the blue that snookers his opponent.

Wilson takes the three-cushion route and fouls twice to gift Allen 10 points.

Allen pots the blue before punishing Wilson for not making the pink safe.

Pang Junxu carries on where he left off by beginning the session by drawing level.

Neil Robertson's break sets up Pang for a superb long pot on a red, and he accumulates 23 points.

Robertson goes ahead, but Pang breaks for 45 to leave Robertson requiring two snookers.

But it's the Australian who finds himself trapped and he fouls.

Pang takes the frame 73-29.

Steven Hallworth
Snooker commentator on BBC TV

Kyren Wilson has been critical of his cue, in fact he says he hates it.

If this game goes to the sword and becomes a dog fight, he will have to rely on his equipment.

But what he might lack in a good piece of wood, he makes up for in grit and determination.

I don't think we've ever had a line up in the second round like we've got. So many of them are potential final matches.

I can't pick a best one, they are all brilliant.

Here's a reminder of how the draw is shaping up.

There was a bizarre moment in the second frame of the first session of this match as Neil Robertson, the 2010 world champion and world number three, conceded the second frame before it was out of reach.

The Australian led 1-0 against Pang Junxu, but missed a black and then conceded with the score at 10-57 to the Chinese player. Robertson was 47 points behind but, with three reds on the table, 51 points were still achievable.

Conceding a frame when you can still mathematically win is not allowed so referee Terry Camilleri then warned Robertson, with the Australian saying he thought he had been 57 points behind.

When the score was explained to him, Robertson said "ah, I miscalculated the score, sorry".

The incident will still cost him a mandatory £250 fine. After their first session, Robertson holds a 5-4 lead, although Pang did make a break of 122 in the last frame of the night.
