"Coming back brought some memories," Chicago forward Patrick Sharp said after his first game at TD Garden since he and his teammates skated there with the Stanley Cup. "We're happy with what we accomplished, but that's in the past and we're ready to try and do it again."
But the NHL's highest-scoring team couldn't do much against the hottest, stingiest club in the league as Tuukka Rask stopped 28 shots in posting his NHL-leading seventh shutout.
"You always feel better about yourself when you play good against good teams like that," he said. "I don't think they got too many chances."
So the Blackhawks, in fourth place in the Western Conference, must wait to pick up the one point they need to clinch a playoff berth for the sixth straight season.
"We're not looking too far ahead," coach Joel Quenneville said. "We're looking to get one more win ... and go from there."
Patrice Bergeron scored two goals and Carl Soderberg had one as the Bruins rebounded from a shootout loss to Montreal on Monday that ended their 12-game winning streak.
In their past 14 games, the Bruins have outscored opponents 51-19. They lead second-place Pittsburgh in the Eastern Conference by nine points with nine games to play for each.
"You never want to play on your heels," Boston coach Claude Julien said. "When you've got a one-goal lead, you want to extend it before you even think of protecting the lead."
The Bruins couldn't do that the last time they played Chicago in Boston. But these Bruins have allowed the fewest goals in the NHL and won their 50th game for just the third time in 31 seasons.
And Bergeron is having one of his best campaigns. Known as one of the NHL's best defensive forwards, he has 25 goals, second-most in his 10-season career.
"It's great any time I can chip in offensively and keep my two-way game," he said.
Soderberg made it 2-0 with his 14th of the season at 5:28 of the third period. Johnny Boychuk's shot was stopped by Kelly in front, and it went to Soderberg, who shot quickly from 15 feet.
Just 13 seconds later, Bergeron was credited with the goal after a video review. Crawford had gone behind his net, and when he tried to get back in front, he knocked the net out of position as the puck was heading toward it.
Officials ruled that the puck would have gone into the net had it been in place.
The Blackhawks played without Patrick Kane, the Conn Smythe Trophy winner last season as the postseason MVP. Chicago's second-leading scorer is expected to miss the rest of the regular season because of a knee injury.
The Blackhawks had few good scoring opportunities. Their last solid bid came when Jeremy Morin unleashed a hard, 30-foot shot from the left side that a sprawling Rask plucked with his glove.
Chicago controlled the puck in the first 10 minutes.
"It was a perfect start. Then it slowed down to a crawl," Quenneville said. "We were not very good."
A moment of silence was held before the game for firefighters Lt. Edward J. Walsh and Michael R. Kennedy, who died Wednesday in a fire in the Back Bay section of Boston, not far from TD Garden. "It's a sad, sad day when two brave men lose their lives," Kelly said. "If we can do a little thing to honor them, we're more than happy to do that." The Bruins wore Boston Fire Department caps during warm-ups. ... Bergeron has a career-best, five-game goal streak. ... The Bruins are 6-0 when they take a 1-0 lead into the third period.
