Meier then gave Switzerland a 2-1 lead with a power-play goal at 18:37, backhanding a rebound in front past Dostal after the goalie made an initial save on Josi’s one-timer.
Radim Simek tied it 2-2 at 6:33 of the third period. Necas collected a loose puck and sent it back to the point, and Simek pounced on a rebound of Chlapik’s redirection in front of the goal crease.
But Pius Suter quickly put Switzerland back in front 3-2 at 8:07 from the edge of the right circle for his second goal of the tournament.
Czechia had what would have been the tying goal waved off at 16:34, when David Pastrnak was ruled to have interfered with Genoni during a power play.
“I thought we battled overall,” Gudas said. “I’m really happy with our effort. Unfortunately, I thought we deserved a little bit of luck, but it’s a tournament that’s short. But if we want to win, we have to go through anybody.”
NOTES: Kukan became the second defenseman to score an overtime goal at Olympics with NHL players, following Drew Doughty with Team Canada in 2014. … Team Switzerland remained perfect against Team Czechia at Olympics with NHL players, claiming its third win in as many meetings (2014, 2006).
