Russia have outclassed Norway 4-2 to make it two wins from two at the Ice Hockey World Championships in Stockholm.
Pavel Datsyuk opened for the Red Machine early in the second period and Denis Denisov soon doubled their lead.
But the Norsemen twice pulled back to within a goal in an action-packed second period before Aleksandr Perezhogin netted Russia's fourth and last on the night just after the second break.
Evgeni Malkin made two assists in the game to take the lead among the best scorers after three days of competition.
"We have key guys like Malkin playing very well," said Russia's defenseman Dmitri Kalinin. "If they continue to do that, we'll see what happens. But we just have to keep playing hard."
While the hitherto perfect Russians prepare for a seemingly harder test against Germany, Norway lick their wounds till the next time they get a chance to beat the Red Machine. They have never beaten Russia – or the Soviet Union – at the IIHF World Championships, losing eight straight times dating back to 1954.
