Kim Yu Na delivered a strong message to world champion Mao Asada with her victory at the recent Four Continents Championship in Vancouver.

After seeing Mao beat her with two triple axels at the Grand Prix Final on home ice in Seoul back in December, Kim knew she had a prime chance to try and regain a psychological edge at the site of the 2010 Vancouver Games and heading into next month's world championships in the United States.

Kim, who won Skate America and the Cup of China this season, continued her strong campaign with an elegant performance in the short program, where Mao struggled.
