Christie wins short track heat, Gilmartin also through

"Jack Whelbourne skated his heat superbly and is the fourth fastest qualifier. Don't write him off - he could be a dark horse in this 1500m event. I am confident he can pull something special out here."
There is no rest for Britain's Jack Whelbourne in the men's 1500m because he will be back in action at around 11:15 GMT in the third of three semi-finals.
The 22-year-old has been drawn against Italy's Yuri Confortola and Sjinkie Knegt of the Netherlands, both of whom he beat in the heats, as well as Canada's Charles Hamelin, Eduarto Alvarez of the USA and home favourite Seme Elistratov.
The top two to go through to the A final and the third and fourth placed finishers into the B final.

"That will make Eve feel better. It was just the one, but it will help to settle the nerves. It hasn't been a great start but it is only 3-1 after four ends."
Take a deep intake of breath and flare those nostrils because there's a whiff of a British comeback at the Ice Cube Curling Centre. Team GB win a point in the fourth end to reduce the gap against Sweden to 3-1.

Curlers can burn up to 1800 calories during a game, which isn't that surprising considering they spend nearly three energy-sapping hours manically brushing the ice.

"Our girls are not far away so they do not have to panic. But they have to get back to basics and keep it simple. A double gets Britain straight back in the game."

"It's not the start Eve Muirhead's team wanted and against the head they have lost three shots in the first three ends - and it has been somewhat of their own making. The Swedes are playing fine and taking their shots."
High-fives from Sweden as they knock Britain's rocks out of the circle. The momentum is with the defending champions. How will Britain respond? Eve Muirhead with the final stone... "Get it," scream the British girls, but their shouts are in vain and they lose two shots to fall 3-0 behind.

BBC Sport curling commentator
"All of these shots are a learning experience and you're seeing how the ice is playing. The result is important but also how the team play and you don't want to play badly in the first match.
"But it's not been a good start for Britain. In the first end everyone looked nervous. It's pretty full in here, probably about 90%, but we have not seen the venue completely full yet.
"It's important Britain do not panic. It's early stages and they want to strike back, but if the opportunity is not there you have to be patient."
Tony Gibbs:, external #lovecurling Keep going GB! 1 down is not much, and you can beat Sweden.

"That was a superb skate by Elise Christie. She didn't panic and kept her head and came round wide for a good win. It was a flying finish by Charlotte Gilmartin and a great performance by her too.
"The disqualification of Russia's Tatiana Borodulina for two false starts in the opening heat was amazing. She must have been so nervous."
Image source, APHas Charlotte Gilmartin qualified for the quarter-finals? It's close, very close, but the Briton's last-gasp dip in the third heat was perfectly timed and the 23-year-old joins team-mate Elise Christie in the quarter-finals.
A trouble-free and composed race from Britain's Elise Christie who wins the heat in 44.775 and progresses to the quarter-finals. The top two qualify and it was home favourite Sofia Prosvirnova who trailed Christie in second.
Elise Christie is on the start line for the 500m women's short track. The starter's bang goes off and the racers sprint into the first corner.

"Eve Muirhead is such a perfectionist. If she does not perform at 100% she will crucify herself. Her team are very consistent.
"You are not going to win the game in the first or second end, you are going to win it in the ninth or tenth end."
Eve Muirhead with the last stone in end two but it's a steal for Sweden, though, and the defending champions ease 1-0 ahead.

The format of the curling competition is straightforward and involves 10 teams playing each other once, with the top four qualifying to the semi-finals. The captain - Eve Muirhead for Britain - decides the tactics and usually plays the often-pivotal last stone.
If the sight of women frantically brushing the ice with brooms and bellowing at rocks is confusing you somewhat then help is available. Not from me of course, that would be ridiculous, but in a cheat sheet on this website.
