"I think Ronnie was getting a bit frustrated. He was getting drawn into a game he did not want to play. He obviously wants to attack now."

A five-frame advantage for Ronnie O'Sullivan, who has produced his best form of the final. He made a break of 131 in the 14th frame and he follows that with an effort of 87 to make it 10-5.

Selby had won two frames in a row, but has now failed to pot a ball in the last two frames.

Ronnie O'Sullivan 10-5 Mark Selby (87-0, O'Sullivan 87 break)

The 14th frame lasted just nine minutes and 26 seconds and was the second shortest of the match so far. The third frame, where O'Sullivan also scored a century, was the fastest of the match lasting eight minutes and 57 seconds.

Now we are seeing the final we expected. O'Sullivan was under pressure and has responded superbly. Soon to be 10-5.

Ash O'Sullivan:, external I hope to see Ronnie O'Sullivan get a 147 in this final. Especially in a deciding frame.

Martin Warren:, external Don't know why but the commentary team of John Virgo and Dennis Taylor is always superb!

Ronnie O'Sullivan's break of 131 in the last frame is the best of the final so far, but does not make it onto the list of best breaks in this year's competition.

It took less than 10 minutes to seal the frame and O'Sullivan then goes on to make his 12th century of this year's championship. His score of 131 is the 747th century of his career, as he closes in on Stephen Hendry's career record of 775.

O'Sullivan is now 9-5 ahead. What a way to squash Selby's spirit.

Mark Selby's mini-fightback is quickly ended by O'Sullivan in the 14th frame.

Earlier on today we asked six-time world champion Steve Davis your Twitter questions.

Here is another answer from the Nugget.

Richard asked: "How can Ronnie be beaten, especially when he gets on a roll?

Steve Davis: "Only by taking every possible chance that you get and by keeping with him. Inevitably there is a lapse in concentration that happens to every player, so when it does, you have to be in a position to capitalise. You feel as if you need to take every chance, but that puts added pressure onto your game."

"There have been matches with big leads and players have been pegged back. You still have to keep on pushing."

"At some stage Ronnie will get frustrated, his rhythm is not great and he is looking ragged."

Ken Doherty says: "This was a bigger frame for Mark to win and he has closed the gap now. He needs to win this session 4-1 as otherwise it is too much of an uphill battle for him. It won't damage Ronnie's confidence though."

A huge slice of luck for Selby. O'Sullivan pots the last red, but the cueball then cannons into the green and it vanishes into the yellow pocket.

Selby does the rest with the remaining colours and it is now 8-5 to O'Sullivan.

Ronnie O'Sullivan 8-5 Mark Selby (45-96)

We have seen a couple of re-racks in this match. Ken Doherty explains why and when they are used.

"You have a re-rack in a frame, as it just saves time when a frame isn't going anywhere and neither player can pot any balls," says Doherty.

"Both players want to get on with the game and so when it becomes a stalemate it is often best just to restart the frame.

"The players will generally ask the referee if there can be a re-rack and sometimes the referee will give the players three shots each to see if something can be resolved, but generally the players will agree on a re-rack themselves."

Ken Doherty says: "This frame is still in the balance at the moment. Mark should have put this frame away already, but he keeps bringing Ronnie back to the table. It is a huge frame in the match."

It is now 63-45 and Selby has just given away 14 points away after clattering into the black twice when aiming for a red.

Selby holds a 63-27 advantage. O'Sullivan needed a snooker, which he has just gained. This could be like a punch to the solar plexes for Selby if he falls further behind in the match from this position.

Ken Doherty says: "If it finishes 10-7 tonight, then it wouldn't be too bad for Mark Selby. He can't play any worse than how he done so far today.

"We would all like to see a close final. We saw in this championship that when he is put under pressure, Ronnie O'Sullivan can still score century breaks, but it can go the other way, so Selby needs to try and find a way back into this match."

A tom:, external Ronnie O'Sullivan is the equivalent of Leo Messi, Muhammad Ali (pictured) and Michael Jordan all rolled in to one.

Andy Jenner:, external Ronnie, when he is focused is unstoppable. I feel sorry for anyone playing him, as they can't compete. Sixth title for him I think.

Martin Garrett:, external Why are there so many football shirts at the Crucible? You wouldn't wear a rugby shirt to a cricket match.

More from 1997 world champion Ken Doherty: "I was lucky to play in an era where I played against three of the all-time greats - Steve Davis, Stephen Hendry and Ronnie O'Sullivan.

"If Ronnie wins tonight he will be very close to equalling Stephen's record.

"Ronnie is the most naturally-gifted player to have ever lifted a cue. When you play him you have to play your own game. I have beaten him and been beaten by him, but when you play against him it is such a buzz as you know you have to be on the top of your game.

"He is one of those players that when you play against him you just sit down and admire him."
