Linus Lindström gave AIK the lead.
In the second period, AIK regained control of the game and five minutes into the period, Pär Lindholm gave the Västerbotten side the lead when he tapped the puck in off an open pass from in-form forward Dylan Sikura.
The same Sikura made it 4-2 in the third period when he took a pass from Oskar Nilsson and fired a direct shot into the top corner. AIK then comfortably controlled the rest of the game, and on the few occasions when Vitkovice threatened a comeback, Linus Söderström stood tall as the reliable last line of defense that he is.
The win puts AIK in a good position to reach their first-ever CHL final. The return leg will be played in Skellefteå next Tuesday.
Linus Söderström was very busy in the first period.
