Men's semi-final: USA 4-5 Great Britain (after five ends)
Thomas Duncan
BBC Scotland in Beijing
Bobby Lammie does an unbelievable job on the sweep. His power is such an asset to a skip to be able to guide the stone.
A big cheer goes up from the British contingent. We've had another chorus from the Swedes too. Absorbing stuff.
Men's curling - USA 4-5 Great Britain
Steve Cram
Curling commentator on BBC TV
Excellent from Bruce Mouat and exactly what was needed.
Semi-final: USA 4-5 Great Britain (after five ends)
Understated precision trumps flashy flamboyance in the fifth end as Britain's Bruce Mouat nudges John Shuster's stone out of the house and scored two for Great Britain as we head into the interval.
Semi-final: USA 4-3 Great Britain (after four ends)
John Shuster definitely seems more a pool guy than a snooker player.
He is not shy of playing with power and ambition. An all-or-nothing, death-or-glory curler.
And for the moment, it is working for him.
Bruce Mouat with the final stone in the fifth end....

Interesting the different strategies - US not afraid to get in there, move the stones around and rely on their skip to rescue them if needs be.
It's fascinating to listen and watch.
Semi-final: USA 4-3 Great Britain (after four ends)
Two countries divided by a common language. And about seven notches on the volume knob.
John Shuster directs the sweeping operation with a serious of earnest hollers and bellows. Sample slogan: "Dig in there buddy!"
Bruce Mouat is altogether more reserved.
"It's really got to go," he calmly pleads to Hammy McMillan and Bobby Lammie on brushing duty.
Great Britain with the hammer and upper hand in this fifth end so far.
Figure skating - women's free skate
Sonia Oxley
BBC Sport in Beijing
Kamila Valieva has been practising her quads in the warm-up, and they are looking pretty solid so there are no obvious signs of nerves. Not even wavering at the noise of all the camera shutters.
She will be the last of this final group of five to perform.

Robin Cousins
Olympic gold medallist figure skater on BBC TV
For any athlete who represents their country , who dreams of the Olympics - the moment was being on the podium and to be able to watch my family have that moment with me
To not have that moment in front of your team-mates is heartbreaking.

The final group is warming up on the ice, including Kamila Valieva…
Kamila Valieva has been introduced to the arena, she’s very popular with some sections of the crowd.
They're into the fifth end in the other semi-final, which sees Sweden 3-1 up against Canada. Winners gets at least a silver; loser has another match to try and win bronze.

Kevan Sangster: Loving the men’s Curling SF with Team GB v US . Return of the Limey Stone Cowboys?
Semi-final: USA 4-3 Great Britain (fifth end)
Thomas Duncan
BBC Scotland in Beijing
The US are not as consistent as GB, but they do love a big occasion.
John Shuster goes for tough shots, and he seems to pull it out of the bag when they make it to the knockouts.
Bruce Mouat and co will be hoping he starts to fluff his lines soon.
Figure skating women's free skating programme
The penultimate group in the women's free skate programme have just finished.
We'll now have a short break before we see the final six, which includes Kamila Valieva, her Russian team-mates Anna Shcherbakova and Alexandra Trusova and the other contenders.
Alysa Liu of USA leads on 208.95 after 19 of 25 skaters.
Many are outraged that Valieva is competing given her failed test. Will she end on top of the standings? What will the reaction be if she does?

That is exactly what everyone says about John Shuster - he finds the shots that matter.
Semi-final: USA 4-3 Great Britain (after four ends)
John Shuster attempting a salvage operation with Great Britain lying one...
What has he got?
He got a 24-carat winner.
Perfectly weighted, precisely plotted and, from Great Britain lying one and looking set to steal, the United States takes two points from the end.
Channel change!

Curling will continue on BBC Two - grab that remote and don't miss a thing!
Semi-final: USA 2-3 Great Britain (after three ends)
The United States are struggling in this end after Christopher Plys makes a bit of mess of his first stone.
He makes slight amends with his second.
But Great Britain's yellow stones are more numerous and better placed in the house.
US lying shot, but British stones are huddled around it.
