We want to hold a 3VS3 basketball game in our school. 10 team, the strength is very uneven. We want a fair and time-consuming plan. Thank you.

Divide the team of 10 into two groups by lot, with 5 teams in each group, then play a single round, and then qualify according to the top two in the integral group, and then A 1 VS B2, A2 VS B 1. Then the winner competes for the championship, and the loser competes for 34 places. It's best to have two venues, and Group AB matches will be held at the same time. This will save time.
