HV71, who in the last round broke a four-match losing streak, started the match best.
They were the clearly better team in the match start, and took the lead fairly after five minutes through Tyler Vesel in numerical disadvantage.
And even though Modo equalized just over halfway into the period, it was still HV who led after the first period, when Jesper Kokkonen after 13.07 took advantage of a post return - to the great joy of the former HV star Fredrik Stillman.
Stillman was hailed before the match, when he was recently elected to the Swedish hockey Hall of Fame.
Norbe acknowledged
In the second period, however, it was Modo who was the better team, and within 60 seconds, the league runner-up turned the disadvantage into a lead, through two quick goals.
But in the third period, Daniel Norbe equalized, when he with a nice direct shot put 3-3.
Decided by extension
The draw resulted in regular match time, and the high-quality and intense match went into extra time.
And just over halfway into the extension came the decision, which got the home crowd in extras.
Jonathan Davidsson faked away Modo's Riley Woods in total, before he with a distinct finish next to the first post put 4-3 - which consolidated HV's series lead.
- I think it is one of my best goals I have scored so far, says a smiling Davidsson to C More.
- It means a lot.
We've had some tough matches, but now we're on again.
