Mark Williams is in the BBC studio.

"I was starting to twitch before the end," admits the 2025 finallist.

Full Willo quotes to come.

Mark Williams' long pot success is 69%. Not bad for a player who says he struggles to see the balls.

A handshake between two left-handed greats, two of the finest players of their both own and this current generation.

But tonight belongs to the elder statesman.

Mark Williams, aged 50, becomes the oldest man to ever reach the World Snooker Championship final.

If Mark Williams sinks the black here, surely that's game over...

He does it!

And Williams celebrates with a fist pump.

Mark Williams is so cool, he doesn't feel nerves like other players, he's very calm.

Mark Williams has not reached the Crucible final since he last won here in 2018.

He is on the verge of ending that seven-year wait now, this break looks potentially match-winning.

Oh! The black wipes its feet before dropping in to the bottom right. Heart in mouth moment.

BBC Radio 3 Unwind's Niall Breslin looks at how the intense pressure at the Crucible can affect a snooker player's mental health and the importance of mental skills for all sportspeople.

A few oohs and aahs as Williams bumps the blue off the jaw of the right middle pocket - it drops in, almost in slow motion.

But Williams remains at the table, inexorably reeling off reds.

Now Judd Trump plays a stunningly cut red - and he's freed up the black!

But he can't find the right angle, and he leaves the black over the pocket.

Could that be a decisive moment?

Mark Williams breaks the deadlock with a well cut red into the bottom right, but gets an inopportune kiss off a loose ball.

He can't build a break, and this frame remains in the balance.

The black is surrounded by three reds, the pink is the wrong side of the baulk line and neither man has scored a point yet in frame 31.

You could cut the tension with a knife.

Interesting factoid - both men have the same largest break in this match so far: 116.

Another indicator of how little there is to separate them.

With the black out of service, this has turned into another very tactical frame. Both men are playing up and down the table, plenty of caution on display.

Judd Trump plays a terrific snooker with the white behind the brown, but Mark Williams worms out of it.

It's "one frame at a time" stuff, don't get ahead of yourself, play the balls that are in front of you, hope your opponent doesn't push on and you never know what's going to happen.

You need to be optimistic as a snooker player.

Frame 31, Judd Trump breaks.

And in doing so, a red ends up right next to the black. The big-scoring colour is out of commission for now.

What a treat these players have served up to this Crucible crowd.
