2. If you can use the double loop and integral system within 6 people. It's just a combination of two people. Pay attention to the different hands. Similarly, there are two forms in pairs. If you win a game, you will get 1, if you lose, you will get 1/2. Finally ranked according to the total score.
3. You can also combine the two. First, the single elimination system will be carried out, and finally the top 8 or 6 will be decided to carry out the double-cycle integral system. This is more exciting and interesting.
4. Decide the champion and keep the record. The winner of the next competition is exempt from the competition. After the new champion is determined, you can challenge the previous champion. Two people play six games, and the highest score wins. If you draw, you will play fast chess (one game 10 minutes), and if you draw, you will die suddenly (5 minutes for red and 4 minutes for black). The red side must kill the black side within 5 minutes and be responsible for the loss. The black side only needs to keep peace in four minutes to win. )
