Kurashev gave the Blackhawks a 1-0 lead at 6:49 of the second period after Seth Jones skated to the goal line and passed the puck to the front of the net, where Kurashev tapped it in.
Mantha tied it 1-1 at 8:11 when he took a pass from Connor McMichael at the blue line, skated through the slot and scored with a backhand.
Strome gave Washington a 2-1 lead at 13:50. He scored from in front after T.J. Oshie hit Chicago defenseman Alex Vlasic behind the net to free the puck for Alex Ovechkin, who passed to Joel Edmundson before Strome was found for a tap-in.
“That’s just what ‘Osh’ brings to the table,” Strome said. “He can do so many different things night in and night out. He’s unbelievable at being an unreal team guy, good on the power play and kind of chips in wherever he needs to, with anything, really. He scores goals, sets up plays, and obviously makes big hits.”
Capitals coach Spencer Carbery said Oshie’s hit was a big lift for the team.
“One-hundred percent,” he said. “Tons of energy on our bench from a play like that. It creates the goal, but just the physicality part of it. The added part of it is it’s a skilled guy who can score, who does things like that, finishes a check that gets everybody excited. On a back-to-back Sunday where you’re looking for spark, that’s one of them right there.”
Dowd extended it to 3-1 at 15:23, sweeping in a rebound while lying on the ice following a collision.
“Honestly, it’s so hard to score from in tight like that,” Dowd said. “Teams play really good defense. It’s tough to get a shot off in today’s game. A lot of the goals are scored down there. I think you saw that tonight.”
