I'm just guessing here but:
1st & 2nd place have a place in the semis, playing from home (relatively sure I read this somewhere).
Top 6 playoffs (I think)
So maybe 3 vs 6 and 4 vs 5 for a place in the playoffs, lowest place qualifier plays 1st and highest plays 2nd.
I can't bring myself to hope, but we have beaten Sintellens twice this year ...
