CALGARY, FEB. 13 -- The Soviet Union hockey team, stymied on the undersized rink in the first period, got goals from Alexei Gusarov and Alexander Mogilny early in the second and beat Norway, 5-0, in an Olympic opener today.

Playing in the Corral, where seats close to the ice prevented expansion of the rink to international dimensions, the second-seeded Soviets couldn't exploit their superior skating and wide-open style in the first period.

Most of the Olympic hockey games will be played in the newer Saddledome.

But the Russians scored twice within a minute in the second period against the 10th-seeded Norweigan team. The Soviets are seeking a second straight hockey gold medal and seventh in nine Olympics.

Gusarov scored a power-play goal from the left point that went over goalie Vernon Mott with 2:34 gone in the period.

At 3:30, Alexander Chernykh fed Mogilny, alone on the right side. Mogilny shot the puck from 10 feet between Mott's legs.

The Soviets made it 3-0 on Vladimir Krutov's power-play goal at 17:13 from the right corner of the crease.

They padded their lead with third-period goals by Andrei Khomutov and Igor Stelnov and outshot Norway by 30-12 in the game.

Twice the Norweigans failed to capitalize on two-man, two-minute advantages. They failed to get a shot on goal with that edge in the second period and its 5-on-3 effort failed in the third.

Sergei Mylnikov was the Soviet goalie. Regular starter Evgeny Belosheikin has a sore leg.

Earlier, Peter Schiller scored at 12:59 of the third period to lift sixth-seeded West Germany to a 2-1 upset victory over third-seeded Czechoslovakia in the first competition of the Games.

Roy Roedger eluded the defense on the left boards and fed Schiller, who broke in on goaltender Jaromir Sindel and sent a backhand shot between the legs. Goaltender Karl Friesen, who faced 31 shots, preserved the victory with several tough saves in the remaining minutes.

Czechoslovakian goaltender Dominik Hasek, considered one of the best in the world, did not play because of a groin injury.
