Two-time champion Mark Williams holds a 10-7 lead over four-time winner John Higgins after a fascinating first day in the World Championship final.

Wales' Williams, 43, surged 4-0 ahead before Higgins got off the mark with a century.

Two further tons helped Higgins, 42, level the final at 7-7 but Williams added one of his own en route to winning three frames in a row. The best-of-35 final resumes live on BBC Two at 14:00 BST on Monday.

The winner will collect the trophy and a record £425,000 in prize money at Sheffield's Crucible Theatre.

Both players are aiming to become the oldest champion since Ray Reardon, who was 45 when he triumphed in 1978, and shared four centuries and eight further breaks of 50 or more.

A quick recap of day one.

Mark Williams took all of the opening four frames, but John Higgins won three of the next four to trail 5-3 at the end of the first session.

Williams took the first frame of the evening to go 6-3 in front, before a run of four frames in five for Higgins, who has made three centuries, brought it back to 7-7.

But just when the Scot was thinking he had put himself in a good position, Williams stepped on the gas again, winning the final three frames. He leads 10-7, 18 is the finish post.

Annie Scott: Dear John, Dear Mark. Please have a late finish tomorrow night because I’ve stupidly booked myself to go out from 7:30 - 9pm tomorrow evening. I will be giving myself a stern talking to, don’t you worry! Thanks. Love Annie xxx

Christophe: Excellent day of snooker. Good three-frame lead going into tomorrow. Mark Williams will now push on to the title.

Mark Hill: Absolutely loving the snooker final. Had a bit of everything and it’s only halfway through.

That was an astonishing last frame with Higgins making a schoolboy error. I knew Higgins could win this final but I wasn't so sure about Williams but he's shown he can. He looks really assured.

John will rest up tonight and have another big push tomorrow. He has the ability to do that.

So how safe is a 10-7 lead? Well, John Higgins led by that margin against Mark Selby in this final after the first day last year, before the world number one fought back to win that 18-15.

So not very safe at all then.

That error lets in Williams and he does the rest to end day one 10-7 ahead.

These last three frames of the day could prove to be crucial, very crucial. Higgins, four behind twice, had pulled it back to 7-7, before Williams has taken the final three of Sunday.

He will sleep well tonight, only eight frames from the title.

Two wonderful exponents of the sport and we've seen two shots that are hard to explain: Mark attempting the double and John trying to get that red out. You could see what was going to happen.

Higgins is 43-48 behind, but there is a red next to a brown close to the pocket. Higgins tries to separate the two, but can only down the brown ball. That could be his last shot of the day. 43-52 now.

Mark got that shot selection wrong by attempting the double into the middle pocket but I can't see John winning this frame in one visit because of the red next to the brown. He'll just be thinking of closing the gap and then playing a safety shot off the red.

A risky red doubled into the middle stays on the baize and gives Higgins a chance to wrap up the last frame.

Hard to know if Higgins would be happy with being 9-8 behind at the end of this second session. He was 4-0 and 5-1 behind, but also had pulled it back to 7-7.

It looks like this frame is in the bag for Williams, but there is no shot on a red after just glancing against the pack. It is now 7-48, but this one is not done yet.

Remember, at no stage today has John Higgins been in front. In fact, there has only been once where he has not been losing, when it was 7-7, but breaks of 118 and 64 in the last two frames from Williams have been good enough to take him 9-7 in front.

A missed long red leaves Higgins scratching his head and Williams with an opportunity to end the day 10-7 in front.

John Higgins is opting for the double a lot tonight, but with mixed success. This one is a no, but it doesn't really matter. 0-17 in the final frame of the day.

I think it is important to go to bed knowing you have the lead but as we've seen in the semi-finals I don't think it really matters for John Higgins because he's so good at coming from behind, as is Mark Williams.

It's just about getting the edges here and there.

Jonny The Sloth: Would love to see Williams win this final, he’s played fantastic snooker over the tournament, definitely deserves it!

Mind-in-Requiem: Mark Williams has played absolutely brilliant today but make no mistake, John Higgins will come back ferociously tomorrow.

So, the last frame of day one.

To win the World Snooker Championship you need your fair share of luck. Watch as Mark Williams got a slice of it with this fluke from frame 15 which he went on to win to retake the lead.

John Parrott

Mark Williams has stepped it up since John made it 7-7. Higgins has just had to sit and suffer. There's certainly nothing wrong with his nerves. He's been superb.

That should have been 8-8, but John Higgins' powerful missed black leaves the door open for Mark Williams and he takes the chance with a 64 clearance.

One frame left today and Mark Williams will definitely start tomorrow with the lead. It will either be 10-7 or 9-6.
