CALGARY -- Count Calgary Flames forward Johnny Gaudreau as one of the bigger fans of the NHL's new 3-on-3 overtime format.
Gaudreau scored 1:38 into OT to give the Flames a 2-1 win against the Chicago Blackhawks at Scotiabank Saddledome on Friday.
"I like it," Gaudreau said. "I think a lot of guys in our locker room like it. We've got a fast D-core that is good with the puck and we've got a lot of skilled offensive guys. I think we like it a lot."
The Flames are 5-0 in overtime thanks in large part to Gaudreau's contributions. He's scored the game-winner in two of the victories and has an NHL-leading four points in overtime.
"It seems like every time he's on the ice, he's so dynamic he can make things happen," Calgary captain Mark Giordano said. "And if he gets that chance, he usually makes the other team pay."
Sean Monahan scored and Karri Ramo made 18 saves for Calgary (8-12-1), who avenge a 4-1 loss to Chicago at United Center on Sunday to win their fourth straight game on home ice.
"We just altogether, our whole team, played a lot better than we did," Gaudreau said. "It wasn't our best effort Sunday in Chicago, and our team in the locker room knew we had to come a lot better prepared to play these guys. They're the Stanley Cup champions. We needed a lot better effort than we did on Sunday."
Scott Darling made 35 saves and Artem Anisimov scored for the Blackhawks (11-7-2), who have split the first two of six straight on the road on their annual "Circus Trip." Chicago, which has gotten points in four consecutive games and five of its last six, plays at the Vancouver Canucks on Saturday.
"They're a good team," said Darling, who made five saves in overtime before Gaudreau's winner. "They create a lot of offense. They've got a lot of good players on that team. They made some nice plays tonight.
"You want to get two points. At the end of the day we battled hard and got one. We'll go from there."
Gaudreau's first shot was stopped by Darling, but Gaudreau stripped Blackhawks defenseman Brent Seabrook of the rebound, threw a quick fake and lifted a shot over the goaltender for the win.
"We had good pressure in their zone for a while there," Gaudreau said. "We got a good shot on net, it bounced out to the other team and I happened to get a quick stick on the puck and it bounced my way and had a little breakaway there.
"I tried to just get a quick deke on him. He's a big goalie and he's making saves from outside the crease when I was shooting on him all night. I figured I'd try to get him in close and get him down and get the puck up."
Darling held the Blackhawks even in the third period, making nine saves before Chicago's first shot at 11:39. He stopped Mason Raymond with an outstretched right pad at 1:30 and denied Monahan near the midway mark of the period from point-blank range. He also blockered away Joe Colborne's shot from the slot with 39 seconds remaining, his 14th save of the period.
"He was the biggest reason why we got the one point," Blackhawks defenseman Duncan Keith said. "He played great and kept us in the game."
Two first-period goals were followed by unsuccessful coach's challenges.
Monahan scored at 15:05, backhanding the rebound of defenseman Kris Russell's point shot past Darling to put Calgary up 1-0. Chicago coach Joel Quenneville challenged the goal, but replay confirmed that there was no goaltender interference before the puck crossed the goal line.
Anisimov tied the game 13 seconds into a penalty to Flames defenseman Dougie Hamilton, sliding in the rebound of Seabrook's one-timer at 16:59. Flames coach Bob Hartley challenged the goal, but replay confirmed no goaltender interference on Ramo by Anisimov.
With an assist on the goal, Patrick Kane extended his NHL career-high point streak to 15 games (10 goals, 15 assists). He is three games away from the longest point streak by an American-born player, a mark held by Eddie Olczyk and Phil Kessel.
Russell sustained an upper-body injury in the first period and did not return to the game. Flames forward Jiri Hudler was scratched because of illness.
