After allowing the Blackhawks to score three consecutive goals for a 3-2 lead in the third, the defending Western Conference champions responded. Marchessault fired a shot past goalie Corey Crawford to tie the game, and 12 seconds later it was Tuch punching one in to put Vegas back in front.

Jonathan Toews, Dylan Strome and Artem Anisimov scored for Chicago. Crawford made 32 saves

Vegas took an early lead when Smith tipped the puck to himself over Crawford, then dove across the crease while shooting it into the net.

Engelland scored for the first time this season when he fired a wrist shot from the point through traffic and over Crawford's glove.

Toews inched closer to his 700th career point when he slammed a carom off the end boards past Fluery and cut Vegas' lead in half four minutes into the second.

Later in the period it was Strome gathering Alex DeBrincat's rebound and firing a shot from a wicked angle to tie it at 2.

Anisimov gave Chicago its third straight goal when he streaked in to intercept Nick Holden's pass and beat Fleury on a breakaway with a backhand.

NOTES: Oakland Raiders owner Mark Davis was in attendance. ... Chicago Cubs slugger and Las Vegas native Kris Bryant was also in the sellout crowd. ... William Karlsson's assist on Engelland's goal was the 100th point with the Golden Knights. ... Toews is two points shy of 700. ... The 18,494 in attendance marked the second-largest crowd in franchise history.
