Before the last stone in the match, which was Russian, Sweden had two stones centrally placed in the nest, well hidden.
The Russian player did not manage to find a way through for his stone but it hit a protective stone and the Swedish victory was clear.
In the eighth round, Anna Hasselborg put a stone that knocked away the Russian who was a little hidden in the nest.
But narrow margin, she pulled a hard stone between two other stones and fixed two points to Sweden who could turn the lead with 6-5 before the last two rounds.
The ninth round ended 0-0.
Before the eighth stone (out of ten) in the tenth time, the Russian team took a timeout.
Which team Sweden will face in the semi-final, which will be decided on Friday at 13.05, is not yet clear.
