If you look at your league schedule, there is a Tuesday missed (March 18).
The All Star game is the next day on Wednesday (this is why on the Standings page, that "weekend" is in quotes.
You will be able to schedule a scrimmage for Thursday (March 20), so most teams will only have two games that week.
But BB schedules two cup games that week. So if you are still in the Cup at that time you will play a cup game on Tuesday at the regular league time; and if you win that, you'll play again on Thursday. For Macedonia, this will be the semifinal and final.
I'm not sure how the All Star voting works. 4 players will be listed at each position, with "votes" next to their names. The top 2 at each position will play in the All Star game. The teams are announced a few days before the game.
