Kyren Wilson is on the brink of a fourth successive frame, thanks to a break of 66.

Kyren Wilson gets himself close to the winning line but misses another black off the spot...

The error isn't punished though - he is quickly back at the table to knock in the one remaining red and take the lead for the first time in the match.

Lei Peifan gets in first in the fifth frame but his first break ends on 21 with a missed pink to the middle.

A couple of reds are on cushions and there's a pack of six that Kyren Wilson will need to disturb if he's to nudge himself in front.

Qualifier Matthew Selt gets a frame under his belt with a break of 106 in frame four.

He trails Xiao Guodong 3-1 at their interval.

The draw for the first round of the World Championship was made on Thursday live on BBC Radio 5 Live.

Seven-time world champion Ronnie O'Sullivan, who has not played competitively since January, was paired with former runner-up Ali Carter in his opening match.

O'Sullivan was victorious in Crucible finals against Carter in 2008 and 2012.

Elsewhere, world number one Judd Trump will play Zhou Yuelong and Masters champion Shaun Murphy will take on World Championship debutant Daniel Wells.

After that earlier Xiao Guodong break came to an end on 73, Matthew Selt required a couple of snookers and chose to play on.

He couldn't get them, though, and it's 3-0 to the world number 14.

All the qualifiers here are strong enough to be able to win. You can be a rabbit in the headlights here but it seems to be less likely these days that a player really folds.

It's more likely that the seed struggles and that was looking like it may be on the cards, but Kyren was excellent to dig himself out of a little hole.

Kyren Wilson is over the line in frame four and, having trailed 2-0, heads to the interval all square with Lei Peifan.

Kyren Wilson builds a lead of 46 points in frame four, the last one to be played before a mid-session interval.

After Lei Peifan misses a long red, Wilson knocks one into the corner and is in prime position now to level the match.

No, it won't be a maximum.

Xiao Guodong lands awkwardly on all of the reds and has to head up for the yellow after red number nine drops.

Xiao Guodong has potted the first eight reds with blacks... a maximum on the first morning? Surely not...

A collector's item - a missed pot with the rest for Kyren Wilson.

But a break of 82 is more than enough to get the defending champion on the scoreboard.

Xiao Guodong registers what we hope is the first of many century breaks at this year's World Championship.

A contribution of 120 puts the Chinese player 2-0 ahead against England's Matthew Selt.

This will make Kyren Wilson feel a lot better about life after falling 2-0 behind.

The world champion drills in a long red and gets a helpful kiss on the blue to set up the first chance of the third frame.

Lei Peifan has looked confident. He's potted some really good balls, got a good start and settled down quickly.

For a debutant it's a wonderful start, and not such a good one for a defending champion.

Scottish Open champion Lei Peifan takes advantage of that Kyren Wilson miss to get beyond the winning line in frame two.

Another black missed off the spot by Kyren Wilson, which gifts Lei Peifan another chance.

Not sure if that was a bad contact or just a poor miss - either way, it's not the start that the defending champion would have wanted.

On Table Two, 14th seed Xiao Guodong made a break of 69 to clinch the first frame of his first-round match against Matthew Selt and he's first in at the start of frame two.

Kyren Wilson gets in first at the start of frame two but, after his opening red, misses a black off the spot.

A decent chance for Lei Peifan to extend his lead.
