However, Chinese teenager Liu Jiayu has shown her capability of making a splash at her first Olympics as the 17-year-old has clinched six World Cup titles. The former martial art apprentice began her snowboard training in 2003 and triumphed at last year's World Championships in Gangwon, South Korea with the highest ever score in the women's event.

In the mass-start snowboard cross, American Jacobellis will try hard to prevent the nightmare in Turin from happening again. Jacobellis, leading all the way down, let the gold medal slip away as she fell in executing the last jump.

Four years later, Jacobellis comes to Vancouver as a favourite again. By now, the 24-year-old is the winner of 19 World Cup races and two World Championships.

Recently, the "lucky" winner Tanja Frieden from Switzerland announced retirement after tearing both Achilles tendons in a World Cup event. This time, Jacobellis, nicknamed "Lucky" promises: "That won't happen again."

As coach Peter Foley said, it was a huge battle to make the U.S. men's snowboard cross team as six riders have been on the World Cup podium this season and only four of them make the Olympic team.

At last, defending champion Seth Wescott is going to lead seasoned Nate Holland, World Championships bronze medallist Nick Baumgartner and three-time World Cup winner Graham Watanabe.

In the parallel giant slalom, the 34-year-old Canadian Jasey Jay Anderson is going to fight hard with the Schoch brothers from Switzerland. Philipp Schoch and his elder brother Simon Schoch made one-two finish at the 2006 Games with Philipp Schoch successfully defending his title. But Anderson has announced that he would no longer compete in the snowboard cross, showing his determination to achieve in the parallel giant slalom.
