This year's Xin Ramen Cup, the top three matches of the world Go team, has changed. The usual 4-6-4 arrangement has been changed to 4-5-5 this year. I didn't pay attention to it at first, but I was waiting for a game between Coulee and Murakawa Daisuke, only to find that it had changed. Probably to ensure that as long as the first two stages win 1 game, you can participate in the third stage. Imagine a team. If there is no bye in the first game, all five players will play. If the game is unbeaten, it will be in 1, 3, 5, 7 and 9 games. If only nine games are arranged in the first two stages, as long as 1 wins or draws, it can be guaranteed that there will still be three teams participating in the third stage.
