The Chicago Blackhawks’ penalty kill has been their Achilles’ heel more than a few times this season. Who would’ve guessed it would be a source of momentum on Tuesday night.

Patrick Kane scored another highlight-reel goal on the power play, and the Blackhawks had a critical three-minute kill in the second period en route to their 3-1 victory over the Nashville Predators. The Blackhawks have won two in a row and five of their last six.

Antti Raanta stopped 27 of 28 shots to improve to 7-1-1 on the season. Duncan Keith had a goal and an assist, and now leads all NHL defensemen with 32 points.

On a night they got Bryan Bickell back after a month-long injury, the Blackhawks were finding answers on both sides of their special teams. The power play continued to sizzle, with the Blackhawks scoring twice on it via Kane and Nick Leddy; they’ve now scored at least one power-play goal in each of their past 10 games.

“I think we have two really good (power-play) units. If one unit doesn’t score the other one’s able to get a goal,” Keith said. “I think we’ve had the same (units) all season, so we have that chemistry with one another with a lot of skill. We’re moving the puck around and just getting shots. We’ve been able to score some timely goals.”

But the penalty kill proved equally vital, especially when they nixed three minutes worth of a Patrick Sharp high-sticking double minor. The Blackhawks went 6 of 7 on the kill, with a Shea Weber blast the only one getting through.
