Chicago's Andrew Shaw, Niklas Hjalmarsson and Marian Hossa scored in the third period after Dallas rallied to tie it, and the Blackhawks went on to beat the Stars on Monday night for their sixth straight win.
Jonathan Toews netted his team-leading 21st goal, and Viktor Stalberg also scored for NHL-leading Chicago, which has points in nine consecutive games (8-0-1). Ray Emery made 16 saves and improved to 16-1.
Jamie Benn scored both goals for the Stars, whose five-game winning streak ended. They got even after falling behind 2-0. Richard Bachman made 23 saves in his third straight start in place of No. 1 goalie Kari Lehtonen, who is out because of a lower body injury.
Bachman has been in goal since relieving Lehtonen in the first period of the Stars' 5-1 win over Los Angeles on Tuesday.
