Claude Giroux scored 5:59 into overtime to give the Philadelphia Flyers an overtime victory over Chicago, cutting the Blackhawks' series lead to 2-1.
Giroux scored on a deflection off Matt Carle's pass to beat Antti Niemi and win the third straight one-goal game in the series.
The Blackhawks, trying to win their first Stanley Cup title since 1961, snapped a seven-game winning streak and a seven-game road winning streak.
Many Chicago fans were in Philadelphia for the game. Despite the loss, they are still hopeful that the 'hawks can win the Stanley Cup.
"The 'hawks deserve it. They are such a great organization and a great team. They're back. We've had a long, long drought since 1961," said Mark Bowden, Blackhawks fan.
Hawks fans who could not make it to Philadelphia cheered their team from a distance. Some of those fans gathered in Merrionette Park at 115 Bourbon Street, a 40,000 square feet entertainment complex, to watch the game.
Hawks fans got to their seats early, making sure they had a good angle on a television. They also had a chance to meet 'hawks legend Dennis Sevard who greeted fans.
"It would be tremendous for the city of Chicago. We all know that. And I think it has been already very good for the economy of Chicago, for the restaurants and bars and the rest of the city," said Sevard.
Once the puck dropped, the fans were glued to the screens. When the 'hawks scored to tie the game in the first period, a celebration erupted.
Actor Vince Vaughn was also in the house wearing his favorite 'hawks sweater.
"I think it's a testament to the team and what they've done. They have been playing great and they have gotten the city excited, so it's been a lot of fun," said Vaughn.
For younger fan, the Stanley Cup experience is incomparable. Twenty junior players for Chicago Jets Club took it all in Wednesday night and were very excited.
"They're the 'hawks. They can do anything," said Sydney Sorkin, young hockey player.
A Stanley Cup victory, whether it happens in Philadelphia or back home in Chicago, is likely to resonate for many years.
Game 4 is Friday night in Philadelphia.
