Luke Davies: This final is gripping! Would love a final-frame decider.

The table hands back to Selby for a safety exchange, as he now trails 19-5. This is tense, safety snooker at its best. Higgins knows that one mistake and it is all over for him.

This is the view from where Selby's family have been watching the match.

No-one is going anywhere. Higgins has just rolled a red in the middle and leads 14-5. Can he extend this final by one further frame?

Watch the closing stages of Mark Selby's 131 century break which has left him just one frame away from the title.

After all the controversy of frame 31, John Higgins lightens the mood by joking that he can't climb on to the table for a tricky shot as he has eaten "too much haggis". A nice moment, and one you can watch again here...

Higgins has to cue over the green, and eagle-eyed referee Jan Verhaas spots that Higgins hits the green with his cue, before sending the cue ball into the pack of reds. Selby gets another four points closer to the trophy.

This is what he had to do...

...and this is what he did.

Selby gets a red to the middle for the first point of what may well be the last frame of the competition and then sticks Higgins in a snooker, with the cueball welded in behind the green. (1-0)

Gary Lineker, who hails from the same city as Selby, writes on Twitter...

Amid all the controversy, Selby has got his mind back on the game (it didn't take long) and is closing in on the title.

He is one away from glory. A century break of 131, to crush Higgins' spirit, takes the Englishman to the brink of the title.

Joseph Rutter: Wouldn't be a May bank holiday without some late-night drama at the Crucible. 

Craig Steeples: Should be going to be bed but gripped by the snooker!!! Yes I said gripped by the snooker!!

Luigina Ciolfi: I'm cross-eyed with tiredness, but cannot possibly stop watching this now... 

Rob Blake: Forgot how much I love this game. Sheer class #thetensionmounts, external

Roxy Dodd: This is getting close. Up early for work tomorrow but no way im missing this.

Back to the action, and Selby has taken his break into the 50s. He is closing in on frame 17 of the 18 he needs. (51-0)

We're getting a bit deep for nearly half ten at night...

Scotty Little: Just looked again and he double hit the white anyway, so he actually fouled twice #bbcsnooker, external

Matthew Hersee: Schrodinger's snooker. Both did and did not hit the black. (Probably depending on who you want to win).

Z‏: "Too much haggis." Only in snooker at such a high level in such a tense stage will you see such scenes.

So in frame 32 (version 2.0) we still haven't had as many points as we had in the original. It's proving to be the tricky sequel at the moment.

James McCann: It gets even better.. a re-rack!

Dean Anderson: This has final frame decider written all over it!

Ben Gosling: You seriously couldn't ask for a better final than this for the Crucible's 40 year anniversary - I'm glued to the screen!

'Too much haggis' jokes John Higgins as he struggles to climb on to the table to reach a long shot.

These bad jokes are contagious. They're everywhere.

David Baker: The debate is bigger than the chicken or the egg did the white touch the black? Ref was spot on.

Andy Powell: Scenes at the snooker. Physics rewritten as black clearly hit from 1 angle, and clearly not from another. Adjudication in: Selby hit the black in 4k, feathered it in HD, missed by a mile in SD.

Watch what the pundits thought about the referee's 'was it a foul' call in the 31st frame.
