Jak Jones looked nervous at the start but now it's Stuart Bingham who is looking more nervous, even though he's won the championship.

Maybe it's because he's the favourite.

Nine times out of 10 he wins the frame from the position he was in when he missed the black off the spot.

He has to dictate the pace of play. He is letting Jak Jones dominate the patterns of play with long bouts of safety.

What a performance from Jak Jones in this third session. His solid technique is standing him in good stead.

Stuart Bingham has something to think about in the interval.

And there we have it. Jak Jones finishes things off to take the frame and ensure a two-frame advantage after winning that mini-session 3-1.

Stuart Bingham will be raging having missed blacks off the spot in successive frames.

Jak Jones goes past the 50 mark. It's his seventh half-century in this match so far and puts him 49 points ahead with 43 points to play for.

Job almost done. An 11-9 interval lead looks likely.

Can you believe it? That's the second black Stuart Bingham has missed off the spot. How costly will that be? A lapse in concentration.

It's getting hot out there.

Jak Jones is steadying himself.

No need for further explanation on that entry. It's all there for the taking for Jones.

Stuart is not taking his chances - he missed the long pot on the green and missed a black off the spot earlier,

You'd think he would kick on with the chances he's had but Jak Jones is sticking in there.

Stuart has missed a trick because he didn't press on.

The final frame before the mid-session interval is under way. And Jak Jones gets in instantly with a sumptuous long red.

I'd say he's been slightly more consistent than Stuart Bingham in this match-up. He's not let a few bad shots affect him too much.

"He's unflappable," says Shaun Murphy.

But the Welshman's break ends on 16 in really unlucky circumstances as he crashes in a red and goes in off the blue.

It is nine years to the day that Stuart Bingham clinched his only world title to date.

Could this be the day he books his place in a second final? The odds have got a bit longer after losing a lengthy 19th frame to trail by one at 10-9.

The 47-year-old would become the oldest world champion in Crucible history, if he were to lift the trophy on Monday evening.

Jak Jones holds his nerve to seal the deal. He leads by one at 10-9.

Stuart Bingham's long pot success is down to 40% in the match now.

That's a big reason as to why Jones is back in the lead.

We're already 37 minutes into this frame. One for the purists.

Stuart Bingham goes for a tough green and leaves it.

This should be frame over.

Jak Jones has given away 99 points from 22 fouls so far in this semi-final.

It's around 10% of the total points that Bingham has scored.

Stuart Bingham has the sniff of victory in his nostrils. He pots the final red and moves onto the colours.

But the green is a problem ball and he has to play safe.

Bingham trails by five points. Twenty five are still up for grabs.

Ball-run Bingham doesn't fully get away with a careless safety. Jak Jones tries his luck with a double and nails it. But he can't pot a colour so plays safe.

One red remains. The Welshman leads by 17 points.

Jak Jones has a terrific technique, a very solid stance and cue action and it's holding up under pressure.

That reliable technique almost results in a fabulous long red but the attempt is just off target. The frame is still very much in the balance.

Jak Jones tries to move one of two tricky remaining reds to a pottable position but doesn't succeed.

The world number 44 has the consolation of a 22-point lead as Stuart Bingham rejoins the action.

This frame hinges on that red on the side cushion. Jak Jones needs the red by the black to win the frame. How does he choose to move it?

Bingham has missed a black off the spot. Unforgiveable, to pinch a Stephen Hendry phrase for such situations.

He doesn't get away with it. Bingham looked set fair but has gifted a great chance to the Welshman. Can Jones make the most of it?

Some sloppy safety play by Jak Jones, resulting in a potentially costly double kiss, lets in Stuart Bingham.

It's nice to see nerves and players miss. They're human, they are on the precipice of the final.

There's a lot riding on this and the chance of lifting the trophy will be in the back of their minds.

Agreed Ken, there are certainly growing signs of nerves out there as we get closer to the business end of this semi-final. It's a scrappy start to frame 19.

Shaun Murphy

What a body blow that would have been early in the session for Jak Jones if Stuart Bingham had pinched that frame with a chance he should never have had.
