If the competition date is not enough, four teams can be selected according to the ranking or strength of each team (if there are previous records) or by drawing lots, which will be divided into two elimination matches, and the winning team and the other six teams will enter the 1/4 finals. Then draw lots for the quarter-finals until the final.
If you don't know the ranking and strength of the 10 team, it is also felt that four teams are randomly selected by lottery, and the 10 team can be randomly selected for matching competition, and the five winning teams and the best three losing teams (calculated as competition results) will enter the top eight. Then draw lots for the quarter-finals until the final. When calculating the score, you can refer to: 1, net winning score and your own team's score. If the first two items are the same, draw lots to decide the qualifying team.
If the competition date is abundant, it can be divided into two groups according to ranking, strength or lottery, with 5 teams in each group. Teams in each group compete, and finally 1-4 players are excluded according to the points. The top four of the two groups entered the quarter-finals, and the quarter-finals played: the upper half: A 1-B4, B2-A3; Lower part: B 1-A4, A2-B3. Finally, it is necessary to arrange the third and fourth place competitions in the semi-finals and finals.
