Chloe Kim, the 17-year-old American, is a big favorite in the women’s halfpipe snowboard competition. She could well have been a contender four years ago as well, but at 13 she was too young to enter. Stay here for live results and analysis from the halfpipe in Pyeongchang:
• Kim can land one of the most challenging tricks in the women’s halfpipe repertoire, the 1080: three complete rotations. And then she can land another, immediately afterward.
• Kim threw down the gauntlet in qualifying, picking up the highest and second highest score of the competition on her two runs.
