Summary — Playoff hockey is a different animal than its regular-season cousin. The Bruins and Sabres proved that on Thursday in Game 1 of their quarterfinal Eastern Conference matchup that was won by Buffalo 2-1 at HSBC Arena in Buffalo. (Recap .)
Thomas Vanek gave Buffalo the early lead at 4:52 in the first period. He was set up by Sabres center Derek Roy, who won the puck coming out of the Buffalo defensive zone and started a break down the right wing. After making the entry, he skated to the top of the faceoff circle and laid the puck up for Vanek, who chose his spot (far side high) on Rask and buried it for the 1-0 lead.
Mark Recchi  got the Bruins back into it during a second period in which his team rarely let the puck out of the Buffalo zone. In the second 20 minutes, Boston outshot the Sabres, 24-8. Recchi tied it on a power play (Toni Lydman – cross check, 8:44) when he found the puck bouncing in the slot after a booming one-timer from the point by Zdeno Chara  that had been set up off the stick of Matt Hunwick. Patrice Bergeron  tangled enough in front of the net to let the puck pass back through traffic on the rebound, and Recchi swept in to put it back on the top shelf at 9:30.
The tie would not last long. Boston was caught sleeping once in the second period, just long enough for Craig Rivet to beat Rask with a slap shot from the top of the right circle for the game-winner. Tim Kennedy set up Rivet with a back pass from the goal line as the Sabres captain came down the wing with a full head of steam at 14:10.
The victory gave the Sabres a 1-0 lead in the best-of-seven series. Game 2 is scheduled in Buffalo for Saturday.
Ryan Miller — The likely 2009-10 Vezina Trophy winner and MVP candidate stood tall for Buffalo, especially in the second period, when the Bruins set a record with 24 shots, the most the Sabres have ever allowed in a period in the playoffs.
Mark Recchi – The veteran scored on the power play in the second period for his 51st career postseason goal, good for a tie for second among active NHL  players.
Tim Kennedy — The Sabres forward was a pest on the ice all night and totaled a plus-two with an assist on Rivet’s second-period goal.
Turning Point — In the midst of withstanding a 24-shot period by the Bruins, Rivet was able to find enough time (which the Sabres had very little of as Boston controlled the puck all period) and space on the right wing to let loose a slap shot after a back feed by Kennedy. The goal stopped Boston’s momentum just enough to allow the Sabres to catch their breath to finish the period with the lead.
Key Play — With Boston trying to claw back in the game towards the end of the third period, two consecutive hard-luck penalties that sapped any momentum it could have gained. The first was on what looked to be a phantom tripping call on Dennis Wideman  when Roy went to the ice with hardly a touch at 13:20. Right after the Bruins killed that penalty, Miroslav Satan accidentally flipped the puck over the boards into the crowd for a delay of game at 15:40 that put Boston on the kill for half of the remaining four minutes.
