Katie Hamshaw: Not looked forward to a lunch break so much in AGES. Let’s go @TeamMouat!

Down to the skips' stones with the house wide open.

John Shuster shunts out the sole British resident to get us going...

The good news for those who haven't been following the curling so far: Great Britain qualified top of the round-robin pool stage with eight wins from nine games.

The bad news: their only defeat was at the hands of the United States, going down 9-7.

The United States are defending champions from Pyeongchang, but were fifth in the recent world championships.

Alice: Tell me you got a bit invested in the Winter Olympics, without telling me you've got a bit invested in the Winter Olympics: You're grateful that your calls ended early to watch the semi-final of the curling.

Malcolm McLeod: 5am here in Calgary and up and 'roaring' to go, cheering on Bruce and the lads in their semi-final!

Some of the women's teams are in the stands, and the Swedish girls have just given us a verse of some supportive tune.

Sweden's men are taking on Canada just now too in the other semi-final.

Eve Muirhead's women's team - who will play their own semi-final against Sweden tomorrow - are in the house to support.

There are a few shrieks of excitement acknowleged by Hammy McMillan and Bobby Lammie.

The pipes play Scotland the Brave once again, as before every session.

Hopefully it gets this Scottish quartet fired up for a huge match. Though maybe not when you've heard it about 50 times already.

On paper and on form, GB should take this match. But never write off John Shuster's USA.

They snuck into the semi-finals four years ago and stunned the curling world by going on to take gold.

They're underdogs, but they'll relish that.

Here we go then.

Is Team GB's very first medal at these Games just a few hours away?

If Great Britain can beat the United States they will be assured of a silver at least, with the possibiility of gold still glinting.

You can watch how this goes down on BBC One or at the top of this page.

The pipers are escorting the curlers to the sheet...

Just joining us? Here are the headlines on day 13 ahead of Great Britain's big semi-final in the men's curling (12:05 GMT).

• GB also snatched a place in the women's curling semi-finals by beating ROC and seeing a series of results go their way in a remarkably tense session.
• Earlier, Great Britain's Zoe Atkin qualified for Friday's freestyle ski halfpipe final with the fourth best score.
• GB's Gus Kenworthy is also into men's final, but he did so by stealing the final qualification place.
• Canada won women's ice hockey gold by beating defending champions USA.

• USA star Mikaela Shiffrin's difficult Games continued as she crashed out of the alpine combined. Michelle Gisin won gold for Switzerland.
• There was also a controversial women's ski cross final as Sweden's Sandra Naeslund won gold but German Daniela Maier was promoted into bronze by the judges.
• Japan's Miho Takagi won the women's 1,000m speed skating.

I am quietly confident but my palms are sweating.

That has all worked out very nicely. The Nordic combined medals are decided.

All eyes now can turn to the curling, plus the figure skating with Kamila Valieva on the ice at 13:45 GMT.

Can Bruce Mouat and team secure a place in the final? The USA stand between them and a guaranteed Olympic medal for Great Britain.

We're halfway through this free skate now and Poland's Ekaterina Kurakova is still leading. No wonder she was so emotional at the end of her routine - she had come into this in 24th place and will now finish at least 11 places higher than that.

Norway almost have their gold in the bag. Just a couple of kilometers remain.

Joergen Graabak has skied this final leg perfectly.

There's a fight behind for silver and bronze.

In the battle between two ice hockey superpowers earlier, Canada held off a comeback from USA to win gold in the women's final.

Canada led 3-0 in the second period and looked on course for a comfortable win.

The USA hit back with two goals late in the final period to ensure a nervy finish, but Canada held on.

This Nordic combined team relay finale is now live on BBC One. You can watch it above too.

The athletes get a less than friendly reception from their coaches as they pass by during this third leg. They roar encouragement/demands in their faces.

The result is the Norwegian athlete makes a break to try and build a lead before the final handover.

The next medal today will come in the Nordic combined team event.

It all ends with the 4x5km cross-country skiing relay, with the teams starting at staggered intervals depending on the standings from the previous stages.

We're halfway through the relay and there's nothing to separate Austria, Norway and Japan at the front.

Germany aren't too far behind either.

Ever wondered about some of the musical inspiration behind some of the world's greatest figure skating routines?

There have been iconic figures from heart-wrenching films such as the girl in the red coat from Schindler's List, anime characters, and let's be honest, what screams figure skating more than borrowing from musicals!

Our friends from BBC Bitesize go through some of there highlights here.

John Shuster is a terrier but the GB boys are playing so well and their momentum has just grown every single game this week and just dominating the game out there.

I don't think it would matter what John Shuster throws at them tonight, they're ready and they're here to do a job.

They've performed so well as a team and everything they're doing is so calm and calculated and it is just clinical, and that is what is so nice to watch.

It's a treat for us as spectators, you don't get nervous because you just feel like they're in control all the time.

I've got no doubts for this evening's game whatsoever.

United States superstar Mikaela Shiffrin's Olympic campaign continued to disintegrate with a third failure to finish costing her any hope of combined gold.

The 26-year-old, who had pulled up early in the slalom and giant slalom individual events earlier in the Games, was beaten to gold by defending champion Michelle Gisin of Switzerland.

Shiffrin will have a final chance to win a medal in Saturday's mixed team parallel slalom event.
