Wonderful first stone from Brad Jacobs. Three yellow stones are scattered to all corners of the Ice Cube. This will be at least one point for Canada, which could well be enough to halt this final. Murdoch puts one in the house, but the Jacobs wrecking ball is about to swing once more...

Time-out called by Britain, coach Soren Gran summoned. What can be conjured up? It could be a case of two stones to keep this match alive.

Granite skidding down ice, rock on rock before GB look to form a yellow guard at the front door. Canada, though, are the bulldozer. Each British wall is knocked down.

Canada are strutting around like Mick Jagger on ice. The minimum amount of time an Olympic final must be played for is eight ends, so we could be seeing the final stones being curled down the sheet. Two each in the house, four each in hand.

A point gained for GB, but yet another mistake prevents what should have been two stones added to the score. The skip simply couldn't keep both stones in an otherwise empty house. Canada to have the hammer in the eighth end. Did Murdoch say this might be the last one?

Rob in Sheffield: The Canadians are giving the Brits something most people will never get - a lesson in curling. This could get embarrassing if Dave and Company don't get it together soon.

Rob from Somerset: Get real, people. We aren't getting gold from 6-1 down before the halfway stage. Brutal, but true.

I'd almost liken this to the last rites of a one-sided Test match. You know who's going to win, but there's still formalities to conclude. Still, bit of perspective needed. Great Britain are winning Olympic silver - the bronzes of the GB women and Jenny Jones were celebrated, and so should this.

"The sounds of 'let's go Canada, let's go,' are the only song being sung in the Ice Cube. It looks a forlorn task for Great Britain as Canada are on the verge of winning the men's curling gold for the third successive Olympics."

Canada continue on their unstoppable black march towards gold. Britain have the hammer in this seventh end, but the Canadian tactic is to simply keep the house as clear as possible. Even if Britain pick up one, or possibly two points here, they won't really hurt Canada, who would then have the hammer anyway.

"I think David Murdoch is trying too hard now. Just play the basic shot, the ones you train on. Now it's a big, big gap to Canada, and it's a huge mountain for Britain to climb.

"This is a terrible way to finish a championships, but don't forget these boys are playing for gold or silver - they are in the final of the Olympics."

If this gap gets much bigger, this match won't be going 10 ends. It's a simple task for Brad Jacobs to roll his final stone towards an unguarded button to give Canada another two points. Only four ends remain.

Conflab for GB as Dave Murdoch prepares for the first of his two stones. Practically no noise in the Ice Cube, bar the scrape of granite on ice when Murdoch sets on his way. He's up against it, leaving Canada with a simple double to knock both yellow GB stones out of the house. Brad Jacobs completes the task, to cheers and bell-ringing from the fans in red.

"Why are Canada's T-shirts so tight? Considering the guns they are carrying..."

Four stones apiece remain, hammer-holders Canada with two hovering above the button. Greg Drummond for GB, but those red boulders aren't for shifting. It all feels a little flat, doesn't it?

"There's a party atmosphere in the Ice Cube as the players take a break. Safe to say the Canada fans are enjoying this the most. The British fans are willing their boys home but it's not happening on the ice at the moment for David Murdoch and co. Canada skip Brad Jacobs used to work in a bank and it doesn't take a maths genius to work out the defending champions have a commanding lead. Can GB come back?"

Break completed, sixth end already on the ice. Canada have the hammer. Could we see something special? Or are the Canadians about to sprint to gold?

"Britain's backs are against the wall and now they've got nothing to lose - they must go all guns blazing and not give anything away. The boys will not be feeling the best but they still have five ends to go. So, they must try to force Canada but it's a lot to ask - Canada are a fantastic team. But it's not over yet - let's have faith."

What about that first half? I suspect no one in Britain was expecting such a big struggle. As I said, Team GB have already completed one big comeback in this tournament, but this Canada team are dominant at the moment. They need little excuse to give it some chat, but right now they are walking the walk too.
