1, serve
In doubles, the ball should touch the right half of the server and receiver. If the referee has doubts about the legality of an athlete's serve, he will award a heavy serve and warn the server when it first appears in a game. After that, the referee once again suspects that the player or his doubles partner's serve is co-occurring, and will award the player a point.
2. Competition order
In doubles, the server serves first, then the server returns the ball, then the server's partner returns the ball, and then the server's partner returns the ball. After that, the athletes returned in turn.
Step 3 score
Except for the round that was sentenced to serve again, the player scored 1 minute in the following situations:
In doubles, the opposing players hit the ball in the wrong order. In a game, the winner is 1 1. 10 After the draw, the winner is the one who scores 2 points first.
4. Order of service, acceptance and commitment
After every 2 points, the receiver becomes the server, and so on until the end of the game; Or until the scores of both sides reach 10, or the rotation serve method is implemented. At this point, the order of serving and receiving remains the same, but each person only serves one point in turn.
5. Determine the server's first game of doubles. The server first determines the first server, and then the receiver determines the first receiver. In the next game, after the first starter is confirmed, the first receiver should be the player who served him in the previous game. In doubles, every time the service is changed, the former server becomes the server, and the partner of the former server becomes the receiver. The player who serves first in one game should accept the service first in the next game.
6. Changes in the position of the deciding game In the doubles deciding game, when one player scores 5 points first, the receiver will exchange the order of receiving the service. In one game, one player in one direction will switch to another direction in the next game. In the deciding game, if one side scores 5 points first, the two sides will exchange.
Bearing. (In doubles, if the score is 5: 1 or 5: 3, after the players are exchanged, the original player becomes the receiver and the original receiver becomes the server. )
7, serving, taking orders and orientation are wrong.
Once the referee finds that the order of serving and receiving is wrong, he should immediately suspend the game, and the player who should serve or receive the service should serve or receive the service according to the order established at the beginning of the game and the score on the field; In the doubles match, when mistakes are found, they will be corrected according to the order established by the party who has the right to serve first, and the game will continue. Once the referee finds that the athletes should exchange places but not exchange places, he should immediately suspend the game and make corrections according to the order established at the beginning of the game and the correct position where the athletes should stand on the field before continuing the game.
In any case, all points before the error is found are valid.
