As the name implies, Swiss wheel is a competition system proposed by Swiss, which was used in chess matches as early as 1895. In this S-match, the first round 16 teams in Switzerland matched by lottery, and Bo 1 1-on-1, and the principle of avoiding the same division was implemented.
After the first round, eight teams of 1-0 competed against BO 1, four teams of 2-0 and four teams of 1- 1, and so did the second half, with four teams of 0-2 and four teams of1-/kloc-.
Teams with the same record will play again until eight teams win three games, including two 3-0 teams, three 3-/kloc-0 teams and three 3-2 teams. These eight teams will advance to the quarter-finals.
The other eight teams will be eliminated, bid farewell to the World Cup, and the competition system that determines the team's promotion or elimination is BO3. To sum up, a team must beat three opponents in five rounds to advance.
Competitive features:
1, fair
There is indeed a strength gap between teams, so the grouping of group matches in previous years is actually unfair to some extent. Some teams are weak, some are dead, and even before the game has started, all the people in the group are basically counted.
But after the first round, Switzerland divided the strong and weak, and then only played against teams with the same record. The balance of power is fair.
2. Gold content of currency
In terms of gold content, it avoids the phenomenon that the previous promotion points are not enough, and the weak team is beaten to get points, because it can only compete with opponents with the same record.
3, put an end to the possibility of water
Although the previous World Cup group match deliberately shielded the opponent's guess, it was true in theory. It is possible, but under the Swiss round robin system, every game is very important, and you can advance directly if you win all the games.
