It was a bit nervy in the first five legs but they've started to relax now, particularly Dimitri.

It's a different Dimitri Van den Bergh to the opening few legs of this match.

Double 10 seals a third consecutive leg for the Belgian who is almost halfway to the final.

Big move from DVDB who smashes in 174 on the Heta throw to help set up double 18, which he takes out with aplomb.

But Dimitri Van den Bergh is clinging on, despite not being anywhere near his best.

HIs doubles haven't been great thus far but he finishes 16s to again close his deficit to a single leg.

Damon Heta comes back from the break refreshed and refocused, with three ton-plus visits in leg six that set up a double 16 chance - and he checks it out, first dart.

No wonder Dimitri was celebrating [heading off for the interval] - he's playing dreadfully, averaging 80, and he's only one leg behind.

Heta must know it's there for the taking with the way his opponent is playing, you've got to be ruthless.

As always we would love your thoughts on tonight's arrows action.

Luke Humphries is threatening a darting dynasty, having won the World Grand Prix, Grand Slam, Players Championship Finals and, of course, the World Championship, over the past few months.

Will he add the UK Open title - and, if so, where does he stand in the list of darting greats of all-time? Or is it too early to ask that question?

Get in touch via the methods outlined above.

The Belgian is in danger of going down by a double break but he has one dart at tops to salvage the situation - and nails it.

Damon Heta still with the advantage as we enter the first mini-break of the semi-final.

Damon Heta's nickname 'The Heat' is an anagram of his surname, obviously.

Big respect to anyone who can create one from Van den Bergh's surname...

Damon Heta hits a big 180.

Dimitri Van den Bergh responds with a bit of a brain freeze. One of his darts is hanging on by a thread but he tries to force a treble 20 anyway - and two of the arrows fall out.

That helps Heta take control and he cruises to a comfortable hold.

The scoring has not been spectacular so far but Damon Heta hits 127 to put pressure on a Van den Bergh double eight - and all three land wide of the wire.

Heta hits double six with his last dart in hand - and celebrates the early break of throw with a big fist pump.

The ITV4 commentators suggesting these two - former housemates - are also sharing the same chalet this weekend at Butlin's in Minehead, which is hosting this event.

And they've also shared the opening two legs as Damon Heta edges another nervy affair with double eight, just like Van den Bergh did in the opener.

Nerves? Little bit.

Dimitri Van den Bergh busts a possible 46 finish by hitting double 11 when he was going for double eight.

But Damon Heta is too far back and DVDB takes out double eight the next time after going exactly the same way.

We are under way, first to 11 legs for a place in the final.

Damon Heta also plays the showman role, with his crazy flame hat and leading the fans in a singalong of his 'Stand By Me' entrance theme.

These pair, close friends off the oche, absolutely hamming it up on the stage, perhaps trying to ease some nerves?

Soon be down to serious business though, no getting away from that - especially for Damon Heta, who is bidding to reach his first ever major PDC ranking final.

Dimitri Van den Bergh is in absolutely no rush to reach the oche, signing autographs and taking selfies with the Minehead fans.

The 'Dream Maker' making a few dreams come true among the crowd. And then he treats them to his dancing skills once he finally gets up on stage.

Right then, the two overseas players remaining in the tournament meet first up.

They are close friends who have even shared a house in the past but that will be put to one side as they vie for a place in the UK Open final.

Their progression to the semis was somewhat contrasting - Damon Heta edged a high-scoring, thrilling encounter with 17-year-old Luke Littler while Dimitri Van den Bergh eased past a below-par Martin Lukeman.

We'll be seeing Damon Heta again shortly - the ITV4 pundits have been looking back at his sensational quarter-final victory over Luke Littler...

Former World Grand Prix champion Alan Warriner-Little: "In any sport, when you get moments like that, you've got to relish them. It was something from the gods, we were bouncing in the commentary box.

"The first two sessions - both players at the top of their game, hitting each other with sledgehammers, it was absolutely amazing."

Former PDC World Championship quarter-finalist Chris Mason: "I can't recall ever seeing two players perform at that level at the same time. We've seen it in spells from Phil Taylor and Michael van Gerwen. But it took something like that to get the better of Luke Littler, that's how impressive his part was in that because Damon had to produce those kinds of numbers.

"We're neutral in this, we don't have a dog in the race so I just wanted to see the drama of a decider.

"It was just remarkable and a great moment for Damon. I've been banging the drum for Damon for the past couple of years and it was great to see him play the darts we know he is capable of."

This is what they're playing for, along with a first prize of £111,000...

A reminder of the two semi-final ties that will kick off the evening session in Minehead.

They were made via a random draw - as happens after every round of the UK Open, the 'FA Cup of Darts' - following the quarter-finals earlier this afternoon.

• Dimitri Van den Bergh v Damon Heta
• Luke Humphries v Ricky Evans
