Kim Yu-na of South Korea won her second Grand Prix of the season with a precise and passionate free skate and Zhang Dan and Zhang Hao of China took their second gold medal in two weeks in pairs.

Yuko Kawaguchi and Alexander Smirnov of Russia completed a quad throw salchow, only the second time the jump has been accomplished in International Skating Union competition, but finished with bronze behind Aliona Savchenko and Robin Szolkowy of Germany.

Weir was less than half a point behind Lambiel going into the free program and ended more than 11 points ahead. That gave him his second Grand Prix gold of the year and a berth in the Grand Prix Final.

In the absence of a quad, Weir relied on consistency in his free skate, hitting all of his jumps with assurance, including the opening triple axel-triple toe loop.

Lambiel has a big quad on his best days, but Saturday wasn't one of them. He missed both planned attempts, putting his hand down on the first and falling on the second; his two axels were only doubles.

His bold steps to flamenco music gave him a two-point edge over Weir on presentation. Andrei Griazev of Russia won bronze.

Weir, who has developed a huge and vocal following among young Russian women, said he was boosted by the crowd reaction.

"It was like a royal welcome," he said.

Skating to the soundtrack of "Miss Saigon," Kim opened with a triple flip-triple toe combination and didn't show even minor faltering until her triple lutz when she landed with a wobble. She sat into her subsequent triple salchow slightly, but recovered her form and had a late-program double axel. Earlier, she made a double axel-triple toe combination.

The gold in Moscow and her win at the Cup of China qualifies Kim for the Grand Prix final, which she won last year.

"Some jumps were unstable," Kim said. "But I got my personal best (score) and I made it to the Grand Prix final, so I'm happy."

Yukari Nakano of Japan won silver, opening with a triple axel and completing an unexpected triple-double-double toe loop cascade. Nakano also qualifies for the Grand Prix final.

Joannie Rochette of Canada moved from fifth place after the short program to win bronze. She made a double axel-double axel combo late in the program, though she put her hand down. She also stumbled coming out of both jumps in a triple toe-triple salchow.

Rochette was aided by the disintegration of Kiira Korpi's free skate. The Finn was third after the short program, but missed all three of her combination jumps.

Zhang and Zhang, who are not related, had small problems skating to the moody soundtrack of "The Myth." He put his hand down on a triple salchow, while there was some synchronization failures in their spins.

Savchenko and Szolkowy opened with a long throw triple flip, but were plagued by problems in the middle of the program until ending with an elegant throw triple salchow.

Kawaguchi landed the quad awkwardly and expressed frustration with other rough points in the program.

But their coach Tatiana Moskvina was delighted with the quad.

"It's always difficult the first time. The fact is that it happened," she said.

In ice dancing, Oksana Domnina and Maxim Shabalin of Russia were in a strong lead after the original dance segment, more than 10 points ahead of Nathalie Pechalat and Fabian Bourzat of France.

The Russians amused the crowd with tongue-in-cheek moves to a Cossack dance, including a straight-line lift where Domnina kicked her legs as if she had been seized by a lusty suitor. Unlike the other contestants, who chose Eastern European music, the French couple stood out with flamenco music that they played to with passion and humor, including Pechalat pulling a fan flirtatiously from her bodice.
