David Murdoch produced an inspired last stone to guide Great Britain to victory over Norway to reaching the semi-final of the men's curling competition in Sochi.
GB prevailed 6-5 against the Vancouver 2010 silver medalists despite trailing going down the final end as Thomas Ulsrud appeared to have inspired his rink to the brink of the last four.
But British skipper Murdoch, who finishing fourth in Canada four years ago, clinched a stunning two with the final stone of the match to book a semi-final meeting with world champions Sweden on Wednesday.
"It's just tremendous - it's great to get into the semi-finals."We've had fantastic support through the week and that game was absolutely incredible.
"We weighed up our chances and we guessed we had a chance to win the game; we're not scared of playing shots like that because it was a chance of getting into the semi-finals.
"We've got a good record against Sweden and they've been in great form by winning most of their games, but you can see now we're really coming into our game."
The British men join their female counterparts in the knock-out stages after Eve Muirhead's rink secured a semi-final against Canada after beating hosts Russia on Monday.
It gives both rinks a chance to secure Britain's third medal of the Games which added to Jenny Jones' snowboard slopestyle bronze and Lizzy Yarnold's skeleton gold, would match UK Sport's pre-Olympic target of three medals and continues Britain's successful association with curling.
