The first three minutes of the second period showcased even more excitement with two goals scored within 1:08 of each other.
Nathan Horton went off the ice for goalie interference just 24 seconds into the new frame. However, it was Boston's Rich Peverley and Chris Kelly that took center stage during the Blackhawks' man-advantage.
Peverley intercepted a pass and brought it through the neutral zone. He made a thread-the-needle pass to a waiting Kelly who put it in over the blocker of Chicago's goaltender Corey Crawford to make it 1-1.
However, that didn't last long, when just 1:08 later, Patrick Kane came back and beat Thomas far side to take the 2-1 lead.
The Bruins still had a number of opportunities to tie it up during the remainder of the period. One of the biggest ones came with 5:28 left in the second period, when Michael Frolick went to the sin bin for boarding Chris Kelly. In the Blackhawks zone, Patrice Bergeron almost netted a one timer, but Brent Seabrook got in the way last minute to block it before it got to the net.
The Bruins now sit at an embarrassing 1-20 (5%) on the power play for the season.
Boston leads in shots on net, putting up 23 while Chicago has only 20.
