Single elimination (plus play-offs) means that all the games can be completed in five games, and each game adopts the best of three games system. If the first two games of both sides become the deciding game of 1: 1, the two sides will be re-selected.
In addition, if there has been a competition before, the last champion and runner-up were 1 and No.2 seed player respectively (1 stands for 1 seed, No.2 stands for No.2 seed player), and they will automatically enter the head-tail position without drawing lots (to avoid premature meeting). The other three teams (No.3, No.4 and No.5) won a game (eliminated one team) first.
If you don't have a seed team for the first time, you will be lucky to draw lots by the way (or draw a lot on the 4th and 5th), because the teams are all odd, so it is impossible to catch up with each other, and there must be a bye, but it is ok for five teams to play a single round robin, but each team has to play four games. This tug-of-war is too tiring and too long, and the venue tools (ropes) are not easy to solve.
It is best to have a single knockout, and the team with the most (such as 4 or 5) will win at most 3 games and at least 2 games.
That's the game. Single round robin has the advantages of single round robin, and you can see the real level, but there are many competitions.
Single knockout has its advantages, saving time, but it is easy to get angry. If you lose a game, you have no chance to win the championship.
