The skinny: Andrei Markov scored his second goal of the game at 1:28 of overtime to give the Canadiens a 2-1 win over the Stanley Cup-champion Chicago Blackhawks and bring an end to a goaltending duel between the Canadiens’ Carey Price and Châteauguay’s Corey Crawford Saturday night at the Bell Centre. The Canadiens did a good job of holding the NHL’s highest-scoring team in check but Marian Hossa tied the game at 1-1 when he scored his 16th goal of the season at 9:22 of the third period. Confidence builder for Emelin: Alexei Emelin had his best game in almost a month and it started with his physical game. Emelin did what he does best, which is to hit everyone who moves. The Russian Olympian was credited with six hits, blocked three shots and also chipped in offensively with an assist on Markov’s first goal. He played 19:42 and was a plus-2. The natives are restless: There was a chorus of boos after the Canadiens failed to get a shot on goal during a power play early in the second period. Montreal finished the night 0-for-3 on the power play. Over the past 10 games, the Canadiens have had 36 power-play opportunities but have scored only three goals. Killer defence: The Montreal penalty-killing unit, which ranks third in the NHL, turned in a strong effort after P.K. Subban was sent off for delay of game late in the second period. The Blackhawks failed to get a shot with the extra man, while the Canadiens tested Crawford four times. Tomas Plekanec had a rush that produced two shots. Crawford then stopped Brandon Prust on a breakaway and managed to get his leg up to deflect Lars Eller’s attempt on the rebound. Plucky Pleky: Is there a Selke Trophy in the works for Plekanec this season? He added to his reputation as a shutdown guy by combining with Brian Gionta and Travis Moen to limit the chances for Jonathan Toews and his line. While Hossa had four shots and scored the lone Chicago goal, Toews and Patrick Sharp were limited to one shot apiece. A little help from their friends: The Canadiens have had several goals waved off because of goaltender interference in recent weeks, but they had a decision go their way when Wes McCauley disallowed a goal on a deflected shot from the point at 2:04 of the third period. McCauley ruled that Michal Handzus made incidental contact with Price in the crease. The goalies by the numbers: Price made 19 saves for his 21st win of the season. Crawford had 36 saves
