Artturi Lehkonen had two goals and an assist, Valeri Nichushkin scored twice, and Mikko Rantanen had four assists for the Avalanche, who raised their 2022 Stanley Cup championship banner to rafters in a ceremony before the game. Alexandar Georgiev made 15 saves.
"Real good commitment and determination tonight. It's good to see," Colorado coach Jared Bednar said. "Checking game looked good. We were getting in and out of our zone, arriving in D-zone coverage really well, and getting clean breakouts. The offensive zone play helped, I think. When you're hanging onto the puck and you're able to get moving and shooting a little bit, you're going to spend more time there."
Jonathan Toews and Max Domi scored, and Petr Mrazek made 30 saves for the Blackhawks.
"I thought the first and the third were really good. I thought the second, I thought we felt the heat, and I thought our focus got lost a little bit," Chicago coach Luke Richardson said. "Overall, I think the guys fought until the end, and that's all we can ask for. But we definitely have to demand more of ourselves."
