CHICAGO (AP) — Roberto Luongo and the Vancouver Canucks were determined that nothing would deter them from playing the hockey they knew they were capable of, the style that they needed against the Chicago Blackhawks.

Facing elimination in a rowdy arena, the Canucks were able to keep their composure. They steered away from ill-advised penalties and relied on Luongo for a 4-1 win Sunday night that sends the Western Conference semifinals back to Vancouver for a Game 6.

"The one thing we know is that we were not going to get frustrated no matter what happened on the ice," Luongo said after his 29-save effort.

"We were going to stick to the game plan and not let other stuff get in the way of the way we play."

Christian Ehrhoff had a goal 59 seconds into the game to quiet the United Center and Kevin Bieksa scored twice for the Canucks.

Vancouver gave up four power-play goals in Game 4 on Friday night when its attempt to play more physical ended up in a penalty-filled 7-4 loss that put the Canucks one defeat away from elimination.

"The two games in Vancouver obviously our emotions in some situations got the best of us," Canucks coach Alain Vigneault said. "We needed to be more disciplined and we were."

The Canucks were able to be aggressive but also play smarter. They kept Chicago's 6-foot-4, 257-pound Dustin Byfuglien away from the front of the net more often and they beat the Blackhawks for the second time at the United Center in this series.

Luongo was able to get a better handle on rebounds than he had on the Canucks' home ice.

"Sometimes you're going to give them up and there's nothing you can do about it. It's a matter of how the puck hits you," he said.

"Unfortunately in Vancouver every time there seemed there was one, it was in the net."
