Pond hockey came to United Center -- or at least an imitation of wide-open 1980s hockey.

Earlier, just when the Kings got a little momentum, the Blackhawks stomped it out as the teams traded goals with Chicago taking a 3-1 lead.
The Kings didn't get much going until midway through the first period but they made the most of their chances when an opportunistic Jarret Stoll scored at 9:49, cutting Chicago's lead to 2-1. Dwight King had the lone assist.
But Chicago went up 3-1 when Brandon Saad scored at 11:06 as the Blackhawks took advantage of a miscue by Kings defenseman
Chicago got off to the start it wanted, taking a 2-0 lead just 3:40 into the game. The Blackhawks scored twice on their first five shots, goals coming from defensemen Brent Seabrook and
Seabrook's goal was a power-play effort and Oduya's came at even strength.
The Blackhawks scored on their first shot of game, just 73 seconds in, a blast from the blue line by Seabrook. Kings defenseman Drew Doughty had gone off for tripping Chicago captain Jonathan Toews.
Oduya extended the lead to 2-0, at 3:40, converting a rebound off Patrick Kane's shot. For Kane, it was only his second point of the series.
The Blackhawks were sparked by their early power play. It had been struggling the first four games of the series, going just two for 13.
Chicago forward Brandon Saad says despite the team's 5-2 defeat, his teammates believe they outplayed the
"The third period was a big momentum for us, even though we lost the game," Saad said before Wednesday night's puck drop. "I think we started to believe and started to feel good about ourselves. I think having that last game, we can carry that over and use that confidence."
Chicago out-shot the Kings 8-5 in the third and got a goal from forward Bryan Bickell. The Kings were in their patented defensive posture, however, and scored an empty net goal by Tanner Pearson to put the game away.
"Lately our habits and doing the little things have gotten away from us," Saad said. "And when we make turnovers, or simple mistakes, they're a skilled team, a good team and they capitalize on it. We take out the turnovers and dumb penalties and I think we should have success."
The Blackhawks also have last year to reflect upon, considering they rallied down 3-1 to eliminate the Detroit Red Wings in seven games in the Western Conference semifinals. "That's a big reason why we have the confidence," Saad said. "Not only that, but you see a lot of teams this year –won three games in a row."
After losing the series opener in Chicago, the Kings handed the Blackhawks their first home playoff loss of the season in Game 2 before winning two more games at Staples Center to take a 3-1 series lead.
The Kings have dominated the Blackhawks in the special teams department, scoring on five of their last 10 chances on the power play. They've held Chicago to one goal in its last 11 opportunities with the man-advantage.
A win over the Blackhawks would see the Kings avenge their Western Conference finals loss to Chicago last year.
