Kim plugged in her music - she said she thinks she was listening to "MotorSport" on that run, "Paparazzi" on her first - dropped in, launched a sky-high method, and then stomped back-to-back 1080s, making her the first woman to do so in Olympic competition.
Seventeen-year-old Chloe Kim rose to the occasion and won gold in the halfpipe.
Pulling out a spectacular array of tricks on each of her three runs - the third of which earned her 98.25 points out of a possible 100 - Kim drew huge cheers from home fans and United States fans alike.
The 17-year-old brought down the hammer on her very first run Tuesday, scoring a whopping 93.75 points.
Chloe Kim became the youngest female snowboarder to win Olympic gold as she dominated the women's half-pipe yesterday, yet if it was not for her father's sacrifice when she was seven it could have been a whole different story. Her fearless riding and goofy personality combine for truly epic halfpipe runs. But halfpipes are hard, the snow is frozen and nothing is for sure. "I really like vanilla Swiss almond", she said, "but I'll be OK with a mango sorbet". "You wait for four years to come here and it's definitely a lot of hype around a 1 1/2, 2-hour time period". It's pretty nerve-wracking. You know you're at the Olympics.
She didn't have to do it. The run was not flawless but it came close.
Liu claimed silver with a score of 89.75 points and American Arielle Gold the bronze four points further back.More news: SC to resume final hearings in Ram Janmabhoomi-Babri case today

Everyone's talking about Chloe Kim, the 17-year-old snowboarder and new Olympic gold medalist.
"The doctors [say] that the more that it happens, the less impactful it is", Gold said. She won her only gold medal at the 2002 Olympics but remained at the top of the sport long enough to miss out, just barely, on her fourth podium Tuesday. "I think today I did it for my family and I am so grateful to them". "She's handled success and pressure with grace and class, and it's refreshing". She was wearing a black neck warmer with "Chloe" embroidered on it and holding a poster that said "Go!"
Three other Americans joined Kim in the final: Gold, Clark and Maddie Mastro.
"I was happy", Jong said.

Kim has been tweeting non-stop during her time in South Korea.
But deep down, she knows where the real thanks belonged. She was glum after the second and jubilant following the third run in which the crowd gasped at every trick. "I don't know if I could do that if I was in his shoes, quit work and travel with our kid full time, leave your life behind".
"I mean, mascot's really cute", Kim said.
