Nothing's going to be easy now. You just feel it. No easy shots for Ben Woollaston any more.

It's hard, but when you get chances you've only yourself to blame.

The tension ratchets up again as Ben Woollaston pots a red but then misses a pink to middle.

He's been in three times in this frame and only scored 13 points.

He's just not thinking clearly at the moment and it's totally understandable.

It's the biggest match, the biggest night of his life as a snooker player. So much on the line.

But it is about thinking clearly when it matters most.

Ben Woollaston runs out of position fairly swiftly and we're back to a safety exchange.

A Ben Woollaston safety goes awry. Mark Selby pots an opening red and is away again.

Again, though, as has seemingly happened so often in this match, there are a gaggle of reds near the top cushion and making a sizeable break will not be easy.

A missed red with the rest ends Selby's break on 12 and Woollaston will get another chance to win frame and match.

That chance that Ken Doherty talks about comes early in frame 18 as Ben Woollaston pots a red to middle and lands on the blue.

He tries to disturb the cluster of reds but hasn't quite got the right angle and that'll be end of break with only six points added.

Wonderful break - and it all came from a little bit of help from his opponent. He missed an easy red to the green pocket.

Then when Selby did get in he played a wonderful shot to the black, using all his cue power. He played a positive shot, into the pack, beautiful, landed on a nice red and went on to construct a lovely break.

You can never discount Mark Selby, no matter how badly he's playing.

Ben's going to get another chance. He has to take it. He can't miss like he did there because he's going to get punished. He just wants a chance and I think he'll get another couple before this match is over.

No century, but an 81 break gets the job done for Mark Selby. 9-8 now.

Mark Selby absolutely does capitalise. Snookers needed for Ben Woollaston.

Now, can Selby - whose highest break tonight before this frame was 38 - make a century?

I'm not sure it would be the biggest win of Mark's life, but if he were to somehow turn this match around from this point and come out the winner tonight, with what he's been through and all the talk about his equipment, it would be a monster win.

Disappointment for Ben Woollaston, who ends up tight on the cushion after going into the pack of reds and a long one to the top corner wobbles in the jaws.

Can Mark Selby capitalise?

Well then... off we go again.

And Mark Selby's first safety from the baulk end goes in-off, leaving Ben Woollaston a thin cut to the middle.

The world number 44 is off and running, with what he hopes will be the break that clinches frame and match.

And... after another series of tippy-tappy shots off the pack of reds, we're going to have a second re-rack.

There's no question it would be the biggest win in Ben Woollaston's career.

He hasn't been at the Crucible for many, many years.

Coming to play one of the best players of all time and his friend and fellow Leicester cueman, and get the win, would be an absolute milestone for Ben Woollaston.

This is Ben Woollaston's first appearance at the Crucible since 2013. He's never won a match in the main draw of the World Championship.

We're going to have a re-rack at the start of frame 17, after a bit of a safety stalemate.

They're not winning the frames in one visit but, at this stage of a match, you don't mind. You'll take two 40s or a 50 and a 30 is enough.

Ben settled pretty well there, he didn't twitch or anything or miss anything easy.

He's close to the biggest win of his career.

It's the hardest frame to win - the one to get over the line.

Snookers required now - Ben Woollaston is about to go 9-7 in front.

And he does.

Mark Selby, the four-time champion, is on the brink of a first-round exit for the second year in a row.

Ben Woollaston breaks down on 49. He leads by 37, six reds left, four of them on cushions.

Mark Selby tries to develop one of them but leaves it over the corner pocket and Woollaston sinks it. Another chance to get within one frame of the second round.

A Mark Selby safety catches the bump of the middle pocket, leaving Ben Woollaston a chance to commence a break with a long red.

He quickly takes the lead in the frame and there are plenty of open reds to go at. Good opportunity to clinch the frame here.

Mark Selby gets the first opportunity in the 16th of a possible 19 frames. He splits the pack of reds off potting the blue but lands on nothing.

Break over at 12 but Ben Woollaston returns to the table with the cue ball tight against the baulk cushion.
