It was looking like an all-too familiar scene at the end of the second period. The Chicago Blackhawks had a lead, this time the rare 2-0 advantage. The St. Louis Blues took away that lead, again in quick fashion. It was a time when the Blackhawks had to ask themselves if they were going to fall in a heartbreaking way again or do something about it? They chose the latter. Bryan Bickell scored late in regulation to tie it and Patrick Kane scored twice, including the overtime game-winner, as the Blackhawks beat the Blues 4-3 at the United Center on Wednesday night. The Blackhawks evened the first-round series at 2-2, with Game 5 scheduled for Friday in St. Louis. It’s no longer surprising when these two teams have dramatic endings. It’s just part of the series DNA now. And for a while, it looked like the Blackhawks were going to suffer another traumatic loss to the Blues. In the final 1:09 of the second period, Vladimir Tarasenko scored a power-play goal and Max Lapierre knocked a shot off the pipe, off Corey Crawford’s back and in to tie it 2-2. “We certainly weren’t happy,” coach Joel Quenneville said. “We’re going along fine and perfectly. We took to many penalties in the second period but we have a 2-0 lead late in the period. That one at the end of the period reminded me of the one late in Game 2. (I thought), ‘Here we go again.’ We started slower in the third because of that, and then we had to press a lot more at the end to get the equalizer.” That press was part of the difference after Tarasenko’s second gave the Blues a 3-2 edge 12:26 into the third period. Stuck in defensive mode in previous third periods, the Blackhawks pressed this time. They also got the much-needed, net-front presence goal. Michal Rozsival fired from the blue line, and Bickell was in front for the redirect to tie it 3-3 with 3:52 remaining in regulation.
