ST. LOUIS -- The Western Conference First Round series between the Chicago Blackhawks and St. Louis Blues has been pretty tight through two games.
In Game 2, a successful challenge by the Blackhawks and an unsuccessful one by the Blues went in Chicago's favor and helped them even the best-of-7 series.
Andrew Shaw scored the tiebreaking power-play goal with 4:19 remaining to give Chicago a 3-2 victory against the Blues at Scottrade Center on Friday. The Blues won 1-0 in overtime in Game 1 on Wednesday.
Game 3 is at United Center on Sunday (3 p.m. ET; NBC, SN, TVA Sports).
A 1-1 game turned quickly when an overturned goal negated a 2-1 Blues lead, and minutes later, Shaw's goal was upheld following a second review.

The Blues thought they had taken a 2-1 lead with 7:54 remaining in the third period when Vladimir Tarasenko scored from the slot off a pass from Jori Lehtera, but the Blackhawks challenged that Lehtera was offside, and the call was reversed after a lengthy delay.
Blackhawks coach Joel Quenneville screamed from the bench to get the officials' attention.
"Someone on the bench yelled, 'It's offside!' and we got it late, I was screaming like a crazy man," Quenneville said. "They give you sometimes the benefit of the doubt. I don't know what the timeline is. This year, it's kind of new; I don't know if there's a real time limit, but I think they give you time to take a couple of looks at it.
"A player initially said it was offside. Then you have communication between the coach and video and says 'Check it out, let's look at it.' Had to get the referee's attention late. ... The offsides ones are the ones that are a little more clear. It's not the ones at the net with contact. There's a lot of leeway, a lot of interpretations, but the offsides are pretty straight, cut and dried."

The Blues didn't think so.
"I watched it a couple times and the puck kind of disappears behind Jori and there's a skate in the air or it's on the ice or where's the puck and all those things," Blues captain David Backes said. "I'm obviously a biased individual in what I think happened, but the unbiased guy said -- and they had plenty of time to look at it -- but we've got to take it up another notch and continue to execute and continue to play, and they found a way to get on the power play and found a way to get an ugly one."
Shaw was on the doorstep of Blackhawks defenseman Brent Seabrook's shot from the point and was able to pop a puck in from right in front of goalie Brian Elliott to break a 1-1 tie.
"I didn't know if they were going to look at goalie interference or not, but I knew I was crosschecked from behind," Shaw said. "I was confident it was a goal but obviously there was some doubt there as well."

The Blues challenged the play for goalie interference but the call of a good goal was upheld.
"We have to put ourselves in a position where those calls don't make or break the game," Elliott said. "I don't know what the rules are anymore. Every play is so different. It's up to the refs on the ice who make the call, not one person kind of calling everything. I don't know what the call is."
Corey Crawford made 29 saves for the Blackhawks. He got his 46th playoff win with the Blackhawks, passing Tony Esposito for first in Chicago history.

Blackhawks defenseman Duncan Keith scored in his return after serving a six-game suspension. He played a game-high 30:59 and had a goal and an assist.
"His energy's rubbing off everywhere," Blackhawks captain Jonathan Toews said of Keith. "I keep saying he's a complete player. He's playing so well and he plays a lot of minutes and he's all over the rink too, jumping up in the play."

Artemi Panarin scored an empty-net goal with 1:26 remaining to make it 3-1. Blues defenseman Kevin Shattenkirk scored with 1.1 seconds remaining to make it 3-2.
Tarasenko's seventh goal in the past eight playoff games put the Blues ahead 1-0 after Lehtera forced a defensive-zone turnover on Michal Roszival, Jaden Schwartz collected it and fed Tarasenko in the slot for a wrist shot at 15:20 of the second period. It was Tarasenko's 11th playoff goal in 15 games.

Chicago tied it late in the period and ended Elliott's shutout streak in the series at 108:59 when Keith's shot from the right point through a screen beat Elliott with 4.4 seconds remaining. After Backes iced the puck, Toews won a faceoff from Lehtera, Patrick Kane deflected the puck to the point and Keith used Andrew Shaw for a screen. Kane had two assists.
"Absolutely huge momentum shift," Kane said. "You talk about goals in the first minutes of periods and goals in the last minute. To have a faceoff with seven seconds left, [Toews] wins a draw, we get it back to [Keith] and he made a great shot. But the whole play doesn't happen if [Shaw] doesn't go to the net. Couple big plays by [Shaw] tonight. Just standing in front he gets rewarded with a goal and screens the goalie on the other one. We need more of that as the series goes on."
