So we have:
USA 12 points
RUS 6 points
SWE 6 points
CZE 3 points
SWE can't get anymore points. CZE-RUS game left, so if CZE wins and gets 3 points, what happens in a 3 way tie?
RUS beat SWE 3-1
SWE beat CZE 3-2 regular time
CZE vs RUS - ? Not played yet.
So if I'm not mistaken in a 3 way tie it's impossible for Finland to face RUS no matter what because RUS beat SWE by 2 goals, while SWE beat CZE by 1 goal, so no matter what RUS stays ahead of Sweden.
Doesn't matter which SWE or CZE Finland faces I guess. CZE has kind of a home crowd and SWE in general is tougher match up for Finland than CZE, although Finland lost to CZE in a practice game not long ago, but Finland got a lot more players since then. Main thing was not to face RUS and maintain the home (stadium) advantage so looks good.
