John Higgins knows he's missed a trick there.

Can Shaun Murphy punish him?

Methodical stuff from John Higgins as he bids to take this to a deciding frame.

The Scot nudges his break up to 50 to put himself in striking distance of the frame, only for his positioning to let him down at a key moment.

Higgins leaves himself with a bit to do on a black into the corner and his cut is too thick which leaves it hovering over the pocket.

Higgins grimaces.

The two pervious frames John started to look weak, he wasn't striking the ball properly.

All of a sudden he's at the point of no return and he's striking the ball as well as you can - incredible.

John Higgins cracks a difficult pink into the bottom-right corner pocket.

That made a lovely crunch as he cued it.

"Shot of the day so far, given what is on the line if he missed it" Stephen Hendry says.

Hard to argue. Higgins' break up to 25 now.

He's given himself a great chance, John Higgins.

There are lots of open reds at the baulk end of the table, but he'd like to get down to the business end and get scoring.

John Higgins breaks the shackles and takes on the middle-pocket gamble and...pots it!

The table is still slightly tricky with the 50-year-old Scot is showing good cue-ball control. A promising break of 10 thus far.

A cautious start to the 32nd frame with neither player willing to take the cue ball from the cushion behind the pack of reds.

Who is going to gamble on attempting to pot a red into one of the middle pockets?

Shaun Murphy is playing beautifully - the way he's come back at John Higgins, when he went two behind, is quite incredible.

He's got that steel, that grit and determination that sometimes he's been guilty of missing over the years, but he seems to have found it.

Shaun Murphy disposes of all but one of the reds in a break of 38.

He attempts to double the final red into the middle - and misses - but with 64 points in the bank the frame is his.

Murphy is now just one frame away from the World Snooker Championship final.

John Higgins attempts to pot a red into the right-middle pocket but it drifts along the cushion and sits over the corner pocket.

"Go Shaun!" cries a member of the crowd.

There's a brief delay while a punter is told to switch off their phone before Shaun Murphy chips away at the reds on the table. Murphy has 36 points and counting to Higgins' 8.

I expected Shaun Murphy to get that, but the tension is building.

Does this suit John Higgins to have a tactical frame? He's a tactical master.

A break of 24 from Shaun Murphy is concluded when he is unable to knock a red up the table and into the top corner.

Both players feeling the pressure here.

Fingernails being bitten down to the quick at the Crucible as this match boils up.

John Higgins misses a black but Shaun Murphy's poor positional play a couple of shots later prompts a long deliberation with the pack of reds tightly grouped.

Murphy superbly cuts the solitary red on the cushion into the corner then sinks the black.

When Shaun Murphy goes behind he doesn't look like missing.

But when he gets on level terms the mistakes start creeping in again.

It's getting tense out there isn't it?

This is going to be a nerve-jangling frame you can just feel it.

John Higgins fails to cut a red into the corner pocket, but Shaun Murphy misses a blue into the top-right corner.

A few nerves showing.

Shaun Murphy with the break-off for frame 31.

"Come on Shaun!" roars a punter before being reminded of the Crucible etiquette.

John Higgins begins with a long red with the cue ball rolling back up to baulk.

The Scot then cuts the green into the middle pocket to bring himself down to the business end of the table.

He seems to have potted a lot of balls in this break.

The frames that Shaun's winning, he's winning comfortably. The frames that John's winning are much closer, more tactical exchanges.

The first two frames this afternoon he won to zero. The first session since the mid-session interval he won to zero. This one he's going to win with three points in reply.
