The Blackhawks hung around long enough, and that patience paid off with a pair of late third-period goals less than two minutes apart to shock the Lightning on home ice in Game 1 of the Stanley Cup Finals.
Teuvo Teravainen scored to spark the comeback and assisted on Antoine Vermette's game winner as Chicago topped Tampa Bay 2-1 on Wednesday night.
Corey Crawford made 22 saves in a solid performance for the Blackhawks, who are attempting to win their third Stanley Cup in the past six seasons.
Chicago also won Game 1 when winning hockey's most coveted trophy in 2010 and 2013.
Alex Killorn scored on a skillful redirection and Ben Bishop stopped 19 shots in defeat for the Lightning, who are making their first Finals appearance since defeating Calgary in 2004.
The series continues with Game 2 at Amalie Arena on Saturday night.
