UP NEXT: Chicago and Vegas square off again on Saturday at 7 p.m. CT in Game 3.
The Blackhawks led in chances in the opening half of the opening frame, but much like in the third period on Tuesday night, the Golden Knights struck in quick succession to take hold of the game early.
First, it was Paul Stastny converting a Jonathan Marchessault centering feed in front, beating Corey Crawford under the blocker from point-blank range for a 1-0 lead at the 10:44 mark of the period. Less than five minutes later, Tomas Nosek, who drew into Game 2 in the place of Max Pacioretty, walked down the far wall on a 2-on-1 and put a shot over the shoulder of Crawford from the circle for a 2-0 advantage at 15:35 of the first.
Things began to turn around in the second period, starting with Dach's first playoff goal in the opening minutes. Off a zone entry, Calvin de Haan tried a shot from the point that was blocked but quickly followed it back up with a second opportunity that Robin Lehner turned aside with a pad, but right sending it right to Dach at the side of the net. The rookie put home the open look to get Chicago on the board at 3:17 of the second.
Fellow rookie Dominik Kubalik leveled things on the power play just past the game's halfway point. Entering the zone off a rush, Kane left a puck for the late-trailing Kubalik near the blue line and the Czech winger walked to the high slot before sending a shot off the post and in at 12:07 of the period.
Mark Stone put Vegas back in front briefly at 17:20 of the second as an Alec Martinez shot from the wall was turned aside by Crawford, but found the shin pad of Stone, dropped in the crease and then was tapped home for the 3-2 lead.
In the dying seconds of the second, Alex DeBrincat found Kane on the far side of the ice and with full attention on Showtime out wide, the winger sent a no-look pass across the top of the crease to Dylan Strome for the 3-3 equalizer at 19:46.
Despite a 16-6 Golden Knights advantage in third period shots, 60 minutes would not be enough to find a game-winner and for the first time this postseason, Chicago played overtime hockey.
After a back-and-forth open to OT, the Blackhawks got pinned in their end for an extended period of time and Reilly Smith found the game-winner in front off a feed from Stastny in the corner at the 7:13 mark.
