Denver, CO (SportsNetwork.com) - Semyon Varlamov stopped 37 shots to record his 100th career victory, as Colorado slipped past Chicago 3-2, at Pepsi Center.
Matt Duchene and Ryan O'Reilly picked up a goal and assist each for the Avalanche, winners in six of their last seven to vault over their Wednesday opponents into second place in the Central Division.
Brad Malone added a tally as Colorado won four of five in the season series from the defending Stanley Cup champions.
"As a team we expected them to come hard the later it got. There's still a long way to go," said Avalanche captain Gabriel Landeskog of his club's opponent. "Tonight was a huge win, and we certainly sent a message. We're not going to give them anything."
Patrick Kane and Brandon Saad scored for the Blackhawks, who saw a two-game win streak halted. Antti Raanta made 26 saves in defeat.
The Avs went up by a 3-1 count during a 5-on-3 power play, as Duchene fired from the outer edge of the right circle and O'Reilly tucked home the rebound in front at 10:53.
Raanta was pulled for an extra skater with more than 2 1/2 minutes remaining, and the move paid off one shift later as Saad's rolling shot inside the left post to make it a one-goal contest.
He went to the bench once more shortly after the ensuing faceoff, but Varlamov only needed to make one quality save, on a long shot up the middle from Saad, in the closing seconds.
"This is another frustrating loss for our team. Varlamov is a talented goaltender, and we haven't found a way to get pucks past him," said Blackhawks captain Jonathan Toews. "We have not matched their intensity and we have much more to show against this team."
Malone earned his first of the season and sent the Avs to intermission up 1-0, when his low shot from the left wing near the boards eluded Raanta at 18:24.
"It was a controlled break. I got some speed along the wall, got the chip and then just shot it. I'm glad it went in," noted Malone. "We have run that play in practice and tonight we got a good bounce on it. There's something very special here and I'm proud to be a part of it."
Colorado led by two at the 19-second mark of the middle frame on Duchene's 22nd of the season, but Chicago responded in the person of Kane, who moved around Avs defenseman Jan Hejda on the right wing and beat Varlamov with a backhander to the near post at 8:23.
