With victory at the Shayba Arena, the U.S. team heads to the finals in women's ice hockey, clinching no worse than a silver medal.
Four years ago, the Americans left the Olympics with a silver medal.
"When that buzzer goes off and it erupted in the arena and we fell short of our goal of being the best in the world, that hurts," Chu, a four-time Olympian, was quoted by the Atlanta Journal-Constitution as saying after Monday's win. "The last four years, that's been our goal."
Chu, who has two silver medals and a bronze, said, "We're going for a different color this time."
In Monday's game, Alex Carpenter and Kacey Bellamy scored in a span of 66 seconds in the first period, and Amanda Kessel gave the Americans a 3-0 lead. Megan Bozek, Kendall Coyne and Brianna Decker each had a goal and two assists.
Canada, a three-time defending champion, will have a chance for a fourth gold in a row with a victory over Switzerland later Monday.
Anna Borgqvist scored Sweden's lone goal.
