Ten round-robin matches took place across three sessions at Wetzikon Curling Club and following the day's play all countries have played three games.

Three nations have won all three of their games - China, Norway and Sweden while three teams are winless - Czech Republic, Estonia and hosts Switzerland.

There were just two matches played in the morning session with Russia beating Canada 8-1 and Sweden beating Czech Republic 6-1 in a match where only one point was scored on each end.

In the afternoon session there were four matches played with a close contest coming on Sheet C as Korea edged out Latvia 6-5, with the Koreans scoring two points on the final end to overturn a one point deficit and claim victory.

The other matches were more one-sided, with Scotland beating Switzerland 8-1, Norway beating Estonia 6-2 and China beating Slovakia 7-2.

In the evening session, Sheet C again played host to a close game as Norway edged out Russia 7-6 in an encounter where the lead changed hands several times.

The Russians led 6-5 with two ends to play, but Norway scored a single point on each end to win by one and maintain their unbeaten record.

The evening's other contests saw China comfortably beat the Czech Republic 8-2 thanks to a score of four on the third end, while Sweden beat Switzerland 5-3 and Canada overcame Korea 6-3.

Three more sessions of round-robin matches take place tomorrow, with 12 games scheduled across four sheets.
