The Chicago Blackhawks have opened both of their postseason series with a win thus far. What happened next didn't work out so well for them last time.

There was no letdown in Game 2, because there was no let-up.

The Hawks detonated offensively, chased Kings goalie Jonathan Quick and walked out of the United Center on Sunday with a 4-2 win and 2-0 series lead in the Western Conference finals.

Andrew Shaw and Brent Seabrook scored in the first period, with Bryan Bickell and Michal Handzus adding second-period goals to send Quick -- last year's Conn Smythe Trophy winner -- to the bench at the 9:20 mark, replaced by backup Jonathan Bernier.

Corey Crawford made 29 saves for the Hawks, allowing only a second-period goal to Jeff Carter and then a power play score with 62 seconds remaining.

Shaw broke through not two minutes into the proceedings.

The sequence began with a strong win along the boards by defenseman Nick Leddy, collected by Brandon Saad and then flipped to Viktor Stalberg in the high slot. Stalberg sent a nifty backhand pass to Shaw streaking in alone, and a wrister to the low glove side beat the Kings' Jonathan Quick for the 1-0 lead at the 1:56 mark.

The Kings enjoyed plenty of offensive zone time and one power play in between but came up empty. After that was over, Seabrook continued his relatively hot scoring touch by beating Quick on another shot the purportedly unbeatable Kings goalie should have stopped.
