Action is under way in the women's 500m speed skating event - the 35 competitors have two runs this afternoon with the lowest aggregate score to decide the gold medallist.

The early pace has been set by Dutchwoman Marrit Leenstra who clocked a time of 39.03 seconds. The favourite is Lee Sang-Hwa of South Korea, the Vancouver champion.

How on earth did Great Britain win that? What must Felix Schulze be saying to his team-mates after that final-stone goober? A steal for Team GB? Perhaps, but think of the sporting pain suffered at the hands of Germany over the years.

Can you believe this? Germany's Felix Schulze makes a complete hash of the final stone of the match to give Great Britain victory. Instead of dislodging the GB brick from the centre of the house, he slides by, giving GB one point in the final end, enough for their second win from three matches.

Just what GB didn't want. Murdoch's final stone collides with a GB guarding brick. The skip blasts a piece of rubber from the ice. Germany have the chance to take the match...

BBC Sport commentator

"I think Andrew Musgrave has to look back on his performance with real pride. He has taken a huge step up and will learn from this and he is young enough to come back in four years time and have another go. The fact he is so disappointed is testament to his competitive spirit."

Amazing, amazing stuff. The penultimate German stone kisses a GB boulder that was guarding the front of the scoring area. That one red GB brick that was in the centre of the house remains there. Skip Dave Murdoch to come with GB's final effort.

Harry Fox:, external Can't believe I'm saying this, but this match is thrilling.

Chloe Richardson:, external It's so tense I can't watch, but it looks so fun, I want to try curling.

Brilliant from Dave Murdoch. Now, it's the red of GB that sits in the middle of the house. Problem is, Germany have two stones remaining to GB's one.

Andrew Musgrave misses out on a place in the men's sprint semi-finals after finishing last in his quarter-final.

The Briton, who has put in the best performance by a British cross-country skier by reaching the quarter-finals, started strongly but slipped back and was unable to close the gap on his rivals.

Two stones left, GB call a time-out. One yellow German stone sits on the blue, second, ring of the scoring area. Head coach Soran Gran is called to consult. What's the shot?

Three stones remain for each team. Germany with the hammer. Only one yellow German stone at the back of the scoring area. Business end (no pun intended).

Team GB might be feeling pretty good about their slopestyle prowess right now, but the US Olympic Team have reminded everyone who's boss - on snowboards at least - with their latest Facebook post,, external saying: "Did #TeamUSA sweep snowboard slopestyle? Yes. Yes we did." Olympic champions Sage Kotsenburg and Jamie Anderson show off the evidence.

This is what I love about the Winter Olympics. For four years, it's almost as if curling doesn't exist. The Olympics come round and BAM! We're all hooked. Tenser than waiting for your last number in the bingo hall right now in this GB v Germany match - and it's only a group game. Imagine what it would be like in the medal matches. Middle of the final end, all square, two red GB stones in the house.

The quarter-finals have just been completed in the ladies' sprint and defending champion and eight-time Winter Olympic medallist Marit Bjoergen of Norway is safely through to the semis.

American Shaun White, who has won halfpipe gold in the last two Winter Olympics, is heading to the final in this year's competition after a stunning first run sees him score 95.75.

"You know the pipe is in bad condition when even Shaun is struggling for speed," says BBC commentator Ed Leigh.

The next highest score in the first run of the second heat is 90.00 from China's Yiwei Zhang, while the highest score from the first heat came from Ayumu Hirano of Japan, who registered 92.25.

Right then, final stone of the end. Dave Murdoch crouches, slides. Red stone drawing from right to left as we look, but the German pressure means GB are forced to take one shot to level the game at 6-6. Good news, no? Not really. GB wanted to keep the hammer for the final end, but if they hadn't taken the shot then, Germany would have been out of sight.

Decisions for GB and Dave Murdoch as three German stones hover around the house. "If you throw a bomb" is the chat. Meanwhile, in ice hockey, Sweden's women have beaten Germany 4-0.
