If GB's men or women curlers lose their semi-final, all is not lost. They will play the loser of the other semi-final for the bronze medal.

The women's bronze medal game takes place at 08:30 GMT tomorrow with the men's equivalent the following day at the same time.

It's not just the women curlers who are in action today, with the men's semi-finals taking place at 15:00 GMT. Sweden - who topped the group with eight wins and a loss - take on Great Britain, while reigning champions Canada play China in the other semi-final at the same time.

Both matches will be available to watch on the BBC, so why not have the GB match on your telly and the Canada v China tie on your tablet, mobile or BBC Sport app?

If, and of course it's a very big 'if' at this stage, Britain's Eve Muirhead and her rink beat Canada, they will take on either two-time reigning champions Sweden or Switzerland (who play each other at the same time as GB v Canada) in the final. That would take place on Thursday.

The IOC page on Vkontakte, a popular Russian social media site, has focused on ice hockey where Russia have been doing well.

"Worth noting that the last man to finish in the first run of the men's giant slalom - and 26 out of the 107 starters didn't - was 26.78 seconds behind leader Ted Ligety. That honour goes to India's Himanshu Thakur. Violinist Vanessa-Mae was also 26 seconds adrift after her first run in the women's event yesterday. But she copped some flak for being famous."

How do you rate Britain's chances of success in the men's and women's semi-finals? Have you been caught up in curling fever during the Games? And have you created a makeshift curling rink at home or in the office using brooms and maybe a mop bucket on wheels?

If Eve Muirhead and David Murdoch lead the men's and women's teams to victory in their semi-finals, it will guarantee them a medal and would make these Winter Games Britain's most successful ever.

It would bring GB's total to at least four medals, matching the four won in Chamonix 1924. But Britain would have one gold, at least two silvers, and a bronze, topping the gold, silver and two bronze won in Chamonix.

Sweden hold a 1-0 advantage over Slovenia as we head into the final six minutes of the second period of their quarter-final at the Bolshoy Ice Dome. You can follow the action via the video stream at the top of the page.

Great Britain's women's curling campaign got off to a disappointing start with defeat to two-time reigning champions Sweden. They bounced back with a 12-3 victory - including a score of seven in end four - over USA.

Eve Muirhead and her team edged an 8-7 win over China and then thumped Japan 12-3. A 10-8 victory against South Korea was followed by an 8-6 defeat to Switzerland.

They beat Russia 9-6 in their penultimate game, which proved to be enough to qualify for the last four thanks to other results, but finished the round-robin stages with an 8-7 defeat to Denmark.

Ever since she saw Rhona Martin win curling gold in 2002, Eve Muirhead has had her sights set on doing the same thing herself. She won three World Junior Championships before getting her first Olympic chance at 19 at the Vancouver Games in 2010.

The team failed to get out of the group stages, but when competing as Scotland, Muirhead led her rink to a dramatic last-stone victory against Sweden at the 2013 World Championships in Latvia.

As a talented scratch-handicap golfer, she was offered golf scholarships to several US universities, but turned them down to pursue her curling ambitions. "With golf, it's tough to make it to the top. I knew from a young age that I had good opportunities to do well in curling," said Muirhead, who is also an accomplished bagpipe player.

We've got just over an hour until Eve Muirhead leads her British rink out into the Ice Cube Curling Arena to take on unbeaten Canada in the semi-finals. Win this, and GB are guaranteed a gold or silver medal.

Germany are sitting pretty at the top of the medal table with eight gold medals among their haul of 15. Norway are second, with seven gold, and Netherlands third on six gold. Britain are 18th with Lizzy Yarnold's gold and Jenny Jones' bronze. Can the GB curlers add to that tally and move us up the table?

"With Sweden scoring on the power play, Slovenia will need to work their way back into the match. The score is a fair reflection though."

Sweden get the breakthrough in their quarter-final against Slovenia, with Alexander Steen scoring his first goal of the tournament with only 90 seconds remaining in the first period.
