1) What happens if associations are an odd number and one can't find an opponent to play with?
2) What's the formula of the tournament? I only know that semifinals (??) are played on the first day. Are there preliminary groups and then knockout stages? Or is it only knockout stages where you are awarded with points towards the ranking? How is it possible to play semifinals right on the first day with possibly 16 to 24 teams playing? And what happens with 5 teams associations that have an odd number of teams?
