That will annoy Ronnie O'Sullivan.
O'Sullivan 5-2 Pang
Another early blunder by Pang Junxu, who takes his eye off an simple red, allows Ronnie O'Sullivan a chance to capitalise on the rest of the table. However, after a break of 37 the Rocket misses a red straight down the cushion with the rest.
Williams 11-10 Vafaei
Lee Walker
Former World Seniors champion on BBC iPlayer
Another very good effort by Hossein Vafaei. He's not going away in this match.
Mark Williams will be disappointed - he got in first and made [a lead of] 35. But he missed a red and this has been the result - an excellent break.
Williams 11-10 Vafaei
Now just one frame in it!
Hossein Vafaei misses the final black but it doesn't matter - he's done enough to clinch the frame with a break of 72.

The match was running away from Pang Junxu but that was a wonderful frame. Pang has given Ronnie O'Sullivan something to think about.
O'Sullivan 5-2 Pang
Pang Junxu takes his opportunity in the seventh after that simple miss by Ronnie O'Sullivan and, after another brief visit by the Rocket, Pang is able to complete the clearance.
It keeps the Chinese player in the contest with one frame of the session remaining.
Williams 11-9 Vafaei
Mark Williams hasn't quite been able to find prime position at any point in frame 21 but he just keeps on potting balls to stay at the table.
But the Welshman, with a 35-point lead, misses a very straightforward red to the corner.
Hossein Vafaei frees the black in potting his first red and then cuts in a very fine black to keep the break going.
Some of the reds have gone safe but there are a couple free for Vafaei to eat away at that deficit.
O'Sullivan 5-1 Pang

A lapse in concentration from Ronnie O'Sullivan on that red. There was no pressure and the frame was there for him.
O'Sullivan 5-1 Pang
A break of 52 from Ronnie O'Sullivan at the start of the seventh frame, but he ends up missing a simple red into the corner pocket. A little bit of side on it cost him, perhaps. A chance for Pang Junxu with the reds well placed.
O'Sullivan 5-1 Pang
Pang Junxu produces a masterful escape from a Ronnie O'Sullivan snooker but cannot repeat the feat later in the frame and concedes it to his opponent.
O'Sullivan has restored his four-frame cushion and will definitely be in front at the end of this session - but by how much?
O'Sullivan 4-1 Pang
Ronnie O'Sullivan is given a sniff after Pang Junxu misses a fairly straightforward pot into the corner pocket, and the Rocket rattles through all but one red with relative ease during a break of 68. Can Pang respond?
Williams 11-9 Vafaei
We're back where we started in this concluding session as Mark Williams and Hossein Vafaei share the first four frames.
The trouble for Vafaei is that the frames are starting to run out in this second-round match.
He makes a break of 74 to reduce his deficit to 11-9.
However, Williams needs to win just two of the possible five frames left in this match to get through to the quarter-finals.
O'Sullivan 4-1 Pang
Ronnie O'Sullivan has his hands resting on his lap, and one knee crossed over the other. He looks fairly relaxed during this sixth frame as Pang Junxu starts with a break of 33.

Dennis Taylor

That was a frame which mattered for Pang Junxu and he's got it on the board.
O'Sullivan 4-1 Pang
A break of 119 helps Pang Junxu reduce the deficit to three frames. That will give him massive boost of confidence after struggling for rhythm.
O'Sullivan 4-0 Pang
Dennis Taylor

It would be nice for Pang Junxu can compile a century break here. This has been much better.
O'Sullivan 4-0 Pang
A break of 93 for Pang Junxu now as he pots the final red and looks to be closing in on winning his first frame in this match.
Coverage has come to an end for now on BBC One, but live action on both tables continues on this page via the "Watch and listen" tab and on the BBC iPlayer.
O'Sullivan 4-0 Pang
After the mid-session interval, Pang Junxu has come out with a bit of aggression. He takes on a couple of long pots and manages to sink a red with the second of them to give himself a chance to attack the pack.
However, he's making life difficult for himself with the black after some poor positional play. He has a break of 30 and 38 points in total so far in this frame, but can the Chinese player get himself on the board in one visit?
Williams 11-8 Vafaei
Hossein Vafaei's thin safety with the rest leaves Mark Williams a chance to clip in a long red, which he does and the 50-year-old then clears the table to take a firm grip on this contest now.
