"This is where O'Sullivan's mind man Steve Peters earns his corn - Selby has now won 10 of the last 12 frames and it will be a very confused defending champion looking for answers in his dressing room."

Aged 28, Ronnie O'Sullivan won his second world title with an emphatic final win over Graeme Dott in 2004. All this despite a horror start where he trailed 5-0.

But the Rocket came back to win 18-8, the joint fourth biggest final win which he went on to equal again in 2008 against Ali Carter.

Will O'Sullivan win his sixth world title? He has got a lot of work to do.

For much of yesterday, there were fears of a one-sided final. That is what it is becoming, but not in the way many expected.

This is the first time O'Sullivan has lost more than 14 frames in a World Championship final. Selby takes his eighth frame out of the 10 to have been played today.

Remember, he was 8-3 and 10-5 down. Now he is 15-12 ahead. The finish line is only three frames away for Selby.

Artist Damien Hirst is at the Crucible, but does not have much to smile about as he watches pal Ronnie O'Sullivan struggling to overhaul Mark Selby.

Hirst, pictured with his 2012 artwork entitled "I am Become Death, Shatterer of Worlds", appreciates the tension both players are under.

In today's Independent on Sunday,, external Hirst says: "It is the most mentally challenging sport.

"I have got a snooker table at home, I have had some lessons and can pot a few balls. But put three people in the room watching me and I miss everything. I can't imagine what it is like doing it in the Crucible in front of that crowd and on live television."

A bad miss from O'Sullivan in the early stages of the 27th frame. He tries to cut it in, but gets his angles wrong and the ball remains on the baize. Selby is 34-4 up and has just forced a mistake from O'Sullivan.

"O'Sullivan is really struggling to keep his head above the mud here.

"As for Selby, I'm not sure I've ever seen a player more at home kickin' and a gougin' in the mud and the blood and the beer."

Seven-time world champion Stephen Hendry will be answering the best of your questions during the interval so if you want to ask him something on this year's final tweet @bbcsnooker, external using #bbcsnooker.

We will have the answers to the best of your questions on this page later this evening.

O'Sullivan is in new territory here. He has never lost a World Championship final. Selby is looking to stamp his authority on the match, in the way O'Sullivan did on Sunday afternoon.

If Selby wins this frame he will have won eight of the 10 frames to be played today, after starting Monday's play 10-7 behind. It is 24-0 to Selby at the moment.

Andrew Walker:, external Looks like being a cracking final this, can Selby hold his nerve?

Lee Carberry:, external I think the scrappy ends to frames are doing Selby a big favour.

Kevin Art:, external Brilliant final, proper matchplay snooker, the best player will win, not the best potter.

Britain's leading female flat racing jockey Hayley Turner is among spectators soaking up the action at the Crucible.

Turner, who rode a winner at Lingfield on Friday and another at Goodwood 24 hours later, made the trip to Sheffield after a family barbecue in Nottingham.

She was joined for the final by fellow snooker lover Amy Weaver, a racehorse trainer based in Newmarket.

"Mark does not play the obvious safety shot. He is looking to put you in the most difficult spot possible to prevent a counter attack. He is just so clever."

John Parrott
Former world champion on BBC TV

"Mark never gives you anything. He plays more intelligent shots than anyone else on the circuit. He breaks your rhythm up and it is hard match play."

Selby has a two-frame advantage for the first time and only needs four more frames to be lifting the trophy.

Ronnie O'Sullivan's 8-3 lead yesterday seems a million miles away from how this match is now.

Ronnie O'Sullivan 12-14 Mark Selby (39-64)

The Crucible has seen some fantastic drama. Here are some the best fightbacks at the famous Sheffield venue.

Steve Davis v Dennis Taylor (1985) - They started the final session with Davis leading 15-12, but Taylor won the title 18-17, on the final black ball.

Stephen Hendry v Jimmy White (1992) - Hendry was 14-10 down, but won eight frames in a row, including three century breaks to win 18-14.

Ray Reardon v Alex Higgins (1982) - Higgins was 13-12 up going into the final session, the scores were level at 15-15 after Reardon won three consecutive frames, before Higgins won the last three to seal the match 18-15.

And almost a fight back..

Peter Ebdon v Graeme Dott (2006) - Ebdon was trailing 15-7 and fought back to 15-13, although he still ended up losing 18-14.

Selby has not been two frames ahead in this match yet. He could soon be. He leads 58-25 with the colours remaining.

Mark Selby's highest break in this match is currently 74.

There have been six previous instances of players winning a final without making a century break. They were Neil Robertson (2010 - highest break of 90), Graeme Dott (2006 - 68), Ken Doherty (1997 - 85), Stephen Hendry (1994 - 89) and Steve Davis (1985 - 87 and 1984 - 84).
