Tre Kronor made its first international appearance since February due to the corona pandemic and national team captain Johan Garpenlöv has invested in mostly young talent from the SHL.
They were not enough at all in the beginning.
After a promising start with a team that above all has offensive strength, it broke defensively.
Goals in powerplay
At the end of the first period, the Czech Republic gained two numerical superiorities in quick succession and struck mercilessly at both.
Detroit defender Filip Hronek, on loan to the Czech league, thundered in 1-0 behind goalkeeper debutant Niklas Rubin, Frölunda.
By then, only ten seconds had passed from the powerplay time.
Next time, it only took a minute for Hynek Zohorna to lift in 2-0 since the Swedish defensive game was again far too passive.
After that, the self-confidence disappeared for a Tre Kronor with seven debutants on the ice and a total of nine in the squad.
Shot in the crossbar
Debutant Jonathan Dahlén, Timrå's king of points who is the only Allsvenskan player in the team, admittedly scored the crossbar in powerplay, but shortly afterwards Jakub Galvas shot 3-0 after he was allowed to go in front of the Swedish goal undisturbed and finish.
Frölunda's successful goalkeeper Rubin was forced to make a number of saves as the Czechs could easily play through time after time.
The Czech Republic also has a young Karjala team, but has mixed up its squad with more experienced national team players, including five from the KHL.
The Swedes got a dream start in the third period when Max Friberg was able to reduce after 1.44 after Anton Wedin played nicely.
The two were prominent in a third period where the Swedes rose in terms of play, but did not manage with more than one reduction.
The Karjala tournament is played in a bubble in Helsinki and a limited number of spectators, about 4,500, are allowed at Finland's matches.
Other matches are played in front of empty stands.
