The arrangement principle of tennis single elimination tournament system is as follows:
First of all, the application forms are sorted by strength.
The competition rules issued by the organizer should indicate that "the entry form of the participating units is sorted according to the strength of the players". Doing so can accurately understand the strength of athletes in each unit, provide a basis for determining the "seeds" and provide information for balancing the strength of athletes in each unit, thus enhancing the fairness, competitiveness and appreciation of the competition.
Second, the seed players are evenly distributed.
The seeds of large-scale competitions are determined according to the technical level of athletes, mainly depending on the achievements of athletes in various competitions. For example, the results of the World Tennis Championships, Intercontinental Tennis Tournament or National Tennis Tournament are often obtained several months or even a year ago.
Third, sports teams and athletes draw lots for positioning.
1, each team draws lots. Each team draws lots first, and then arranges in this order from the player of each unit 1, and then arranges from the player of No.2 based on the principle of fairness and reasonableness, and so on, and then arranges in turn, coding the athletes in turn, and then determining their positions according to the player positioning table.
If a single seed athlete can be determined in advance, it can be drawn out and ranked before player 1, and the serial number of athletes can be rearranged from 1.
2. Seed positioning: In order to facilitate the lottery, arrange the bye position and distinguish between seeds and non-seeds, the seeds can be fixed in a certain position. Generally, two methods are adopted:
Following the seeds: after the first and second seeds are positioned, the third and fourth seeds are positioned according to the "following" method of seed position, that is, the third and second seeds are fixed at the top of the lower half, and the fourth and first seeds are fixed at the bottom of the upper half. According to this method, the following seed position table can be arranged.
Batch draw: usually used in competitions with more than four seeded players. First, fix the 1 seed at the top of the upper half and the No.2 seed at the bottom of the lower half. After that, the No.3 and No.4 seeds did not follow up, but drew lots to determine their positions.
If there are eight seeded players, continue to draw lots to determine the position of the fifth to eighth seeded players respectively; If there are many seeded players, this method is also used to determine their positions.
3. Player Positioning: In each event, the first and second players of the same unit should be assigned to different half-court areas. If possible, the third and second players are in the same half area, and the fourth player is in the same half area as the first player.
Fourth, goodbye, grab the number.
When the number of teams (people) is not a power of 2, the nearest power greater than the number of teams (people) can be selected as the number, and the number of bye teams can be calculated so that the number of teams in the second round is exactly a power of 2. When arranging, we should pay attention to make the number of bye teams evenly distributed in all districts, and at the same time, seed athletes (teams) give priority to bye.
If the number of teams (people) is slightly greater than the power of 2, there will be too many seats if bye is arranged. At this time, it can also be solved by the method of "grabbing the number", that is, taking the nearest power of 2 less than the number of teams (people) as the number of numbers, and some teams (people) grab the number.
Grab the number means that two teams (people) use a number, play a game first, the winner monopolizes its number, continue to participate in the game, and the loser is eliminated.

Basic principles of winning tennis singles;
Rule 1: Pass the ball back to the opponent's court effectively, smoothly and without mistakes.
There is a famous saying that tennis match is a contest of match mistakes (tennis? Is it an a? Therefore, as amateurs, we are often the one who makes fewer mistakes and laughs last. So in any case, we must strive to beat our opponents more effectively.
Whether the posture is elegant, whether the return ball is powerful, whether the technique is professional, whether someone stops to appreciate it ... it doesn't matter at this scoring moment! Get rid of all distractions and slow down.
Rule number two: attack each other's weaknesses.
If it is the first time to play, you must warm up with the ball before the game, understand your opponent's hitting habits, and find out the weak links in their technical links. Make a scoring strategy for your next game. If the opponent's backhand is weak, you should hit the ball as much as possible during the game.
If the opponent is not good at moving, he should combine long and short balls and move left and right. If your opponent is oppressive but has a high error rate in handling high balls, you might as well send more moons to disrupt his rhythm.
