Kim Yu-na of South Korea stole the limelight of the Vancouver Olympic Winter Games on Tuesday when five gold medals were decided from skating and skiing.

The world champion defeated her nearest rival Mao Asada of Japan in women's figure skating short program, earning 78.50 points with her Olympic Games James Bond routine, world best score in women's figure skating.

While in men's speed skating, Kim's compatriot Lee Seung-Hoon became the luckiest man, winning the men's 10,000 meters after Sven Kramer of Netherlands was disqualified for a crossover mistake.

The women's figure skating in Vancouver could be a rivalry between Kim and Asada, also world championship title holder.

Skating after Asada, Kim gave a flawless performance which scored her world best points, breaking her personal best and the world record of 76.28 set at Skate America in November last year.

"(Skating after Asaka) I was a little worried but there was no pressure," said Kim."I have been waiting for this for a really long time. I felt comfortable and I was able to enjoy my short program today."

Kim lost just twice in the past two seasons, both times to Asada at the 2008 world championships and the 2008-2009 Grand Prix Final.

Lee Seung-Hoon, a surprised winner in the 5000m speed skating 10 days ago at the Richmond Olympic Oval, renewed the Olympic record in a time of 12 minutes 58.55, slicing 0.37 seconds of the previous mark set by Jochem Uytdehaage of Netherlands on Feb. 22, 2002.

Lee's victory came only after the three-time world champion and record holder Kramer clocked 12:54.50, but later was disqualified for incorrect changing of lanes with 8 laps remaining of the event.

Lee became the first ever Asian champion in the long distance at Winter Olympic Games and probably the luckiest champion in Vancouver.

Lee said: "Today I did my very best and that's the best record I could do today. I'm lucky to get this medal. On the other hand, had Kramer not been disqualified, he would have had it. I know I am lucky. I will work harder to become a better skater and I'm extremely happy."

In Cypress Mountain, Canadian Ashleigh Mcivor dashed out of the snowing course to win the first Olympic gold in the women's ski cross event.

Mcivor, 26, pushed herself forward quickly after a strong start and led the four-member big final squad in bigger and bigger gap. When the reigning world champion rushed to the finish line first, the home crowd were inspired by the sixth gold medal of Canada so far.

Norwegian Hedda Berntsen and Marion Josserand from France grabbed the silver and bronze respectively.

��This is just the most amazing thing in my entire life. I am so proud of myself. There's nothing I could have done to be better equipped,�� said Mcivor.

Austrian Alpine skiiers continued their power on Tuesday, beating the United States to defend the Nordic Combined team title.

The quartet of Bernhard Gruber, David Kreiner, Felix Gottwald and Mario Stecher started the 4x5km cross country stage 36 seconds behind ski jump winners Finland.

But after Gottwald had put the defending champions in the third leg, Stecher held off United Stats' world 10km large hill champion Bill Demong to seal gold in 49 minutes 31.6 seconds.

Demong pushed the Austrian close to capture United States' second ever Olympic Nordic combined medal, but fell back in the sprint finish to score silver, 5.2 seconds back.

Germany lay fifth after the ski jump but gradually cut their way through the field to capture bronze, 19.5 seconds down on the winners.

Other two gold medals went to Russia and Switzerland with Russian biathletes taking the women's 4x6km relay and Swiss Carlo Janka winning the men's giant slalom race.

After 11-day competitions, the United States and Germany both had seven gold medals. Norway, Canada and Switzerland each took six.

In men's curling round robin, host Canada won all its group stage matches after beating China 10-3. In the semifinals on Thursday, Canada will meet the winner between Britain and Sweden, who finished in a tie for fourth spot and now face a Wednesday play-off.

In another semifinal of men's curling, Switzerland will take on Norway.

After 10-day competitions, China, Sweden, Canada and Switzerland advanced to the top four. In Thursday's semifinals, China will meet Sweden and Canada play Switzerland.

While in men's ice hockey, Canada trounced Germany 8-2 to setup a quarterfinal showdown with Russia on Wednesday.
