In tennis, what does it mean when AD is tied in the middle of the game?

AD is an abbreviation for Serve First.

To understand a tennis game, you should first understand the "game" and "set" of tennis. In a "game", one side serves, and for the serving side, this game is a "service game". The old English tennis tradition of 0 is retained, which is "love" (from French), the first ball won by a player is counted as 15 (fifteen), the second ball won is counted as 30 (thirty), the third ball is counted as 40 (forty), and the first player to win four balls is counted as he wins the game.

However, if both teams score three points, i.e. 40:40, it is a "duece". After the "tie", when one side scores one point first, it is "advantage".

Take the lead" and then score one more point to win a game; If one side "takes the lead" and the other party scores another point, it is still a "tie". And so on until one side wins by two points. When one side wins six games first, it wins one set.

However, in the event that both teams win five games, one side must win two games to win a set. If the score of the game is 6-6, the tiebreak system is used to score (tiebreak, also known as tiebreak), that is, 7 points are scored to win the game and the set, if the score is 6 at the time of "tie-break", one side must win by two points to win.

When both sides hit a duece with 40 points, one of them takes the lead and it is AD, which is advantage, which means that the tie has the lead.

AD is an abbreviation for Serve First.

AD stands for "Advantage Serve" or "Advantage".

Players are awarded 1 point for each goal they win, and the first player to win by 4 points wins a game. However, if both teams score 3 points each, it is a "deuce". After a "tie", if one side scores 1 point first, it is "advantage serve" or "advantage".

Occupy 1 more point to win a game.

Tennis matches are divided into two formats: singles and doubles.

The player hits the ball over the net with a tennis racket and falls onto the opponent's court. The aim of each player is to try to hit the ball on the opponent's court. This is done again and again until one of them hits the ball out of bounds or misses the ball.

Before the official match, it is necessary to determine who will serve first in the match. Throughout the match, players from both sides take turns serving. The server should stand behind the end line, between the midpoint and the putative extension of the sideline before serving.

The ball sent should be crossed over the net and landed in the opposing opponent's teeing area in the opposite corner. The first score of each game is counted as 15, the second score is 30, and the next is 40.

In each game, you need to score at least 2 more points than your opponent to end the game. Only one more point in the new doubles rules can be won.

After scoring 40 points equally, the ball won first, which side has the first advantage, AD (advantage).

A method of expressing the score after the first AD (advantage) deuce.

Tennis is divided into sets and matches, which are generally won by winning 2 games in 3 sets, and men will win 3 games in 5 sets in Grand Slam and Masters tournaments.

You have to win 6 games in a set to win, and 5-5 usually has to play 7 games, and 7 games are still usual, you have to enter a tie-break. That is, whoever grabs 7 points first wins, and if it is tied, it is necessary to keep playing, knowing that one side is 2 points ahead of the other party, that is, winning 2 points in a row is considered to win, and the score of grabbing seven is 1 point and 1 point.

There are 4 points in a game, 15, 30, 40, 60 (usually 60 does not appear, because a game has already been won, 60 points are rarely mentioned).When 2 players reach 40 points, it is the duce who wins 2 points first Among them, winning one point first is called AD, and winning one point again will win the game, and losing one point will return to the tie

As for the non-scoring situation you mentioned, it could be that there was an interference on the spot and a replay was required, or that the player had a dispute about the correctness of the ball, or that a relatively junior error was not scored.

AD means to take the lead, tennis matches have to win by two points to win, use AD to indicate the first point, when you win one more point, you will win. AD is an abbreviation for Advantage.

Scoring methodology. Win 1 game (1) 1 point for each goal win, and the first to win 4 points wins 1 game. (2) When both sides score 3 points each, it is a "tie", and after a tie, the net win is 2 points to win 1 game.

Win 1 set (1) A team wins 6 games to win 1 set. (2) When both sides win 5 games, one side wins 2 games to win 1 set.

Tiebreaker Scoring System There are two scoring systems for a draw of 6 games per set. (1) Long handicap system: one side wins two games to win 1 set.

2) Short handicap system: Except for the tiebreaker, unless otherwise specified before the match, the following methods shall generally be followed. a.

The first player to score 7 points wins the game and the set (if the score is 6 draws, the team must net 2 points). b.The first player serves the first point, the opponent serves the first point, and then takes turns serving the two points until the end of the game.

c.The first point is served on the right, the second on the left, and the third on the right. d.

Courts are swapped every 6-point shot and the end of the tiebreaker.

Scoring in the short handicap system (1) The first ball (0:0), the server A serves 1 point, and the serve is changed after 1 point. (2) The first ball (1:

0 or 0:1, do not report 15:0 or 0:

15), B serves, B serves two points in a row and then changes the serve, first serving from the left area. (3) The first ball (reported at 3:0 or 1:

2, 2:1, not 40:0 or 15:

30, 30:15), serve from A, change serve after A serves twice in a row, and then change serve, first serve from the left area. (4) The first ball (report 3:

3 or 2:4, 4:2 or 1:

5, 5: 1 or 6: 0, 0:

6) After B serves 1 point, the court is changed, and if the game is not over, B continues to serve the 7th ball. (5) The score is played to 5:5, 6:

6，7：7，8：8……, a two-point winning streak is required to determine who wins.

Therefore, most of the current rules follow the methods of the time. In ancient times, the number 15 had a special significance, and it was believed that the basic unit of tennis was 15, which was the division correspondence of the sextant designated by reference to the astronomical sextant. Therefore, tennis is scored on a 15-point base.

One point is counted as fifteen (15), followed by thirty (30), forty five (45), and game (win). But this creates a problem, that is, the first two points are one word, but when forty five becomes two words, it is inconvenient to report and score, so it is simplified to forty (40). So the modern rule has always been to report:

love(0), fifteen(15), thirty(30), forty(40), game.

After the tiebreaker is played, the Israeli players exchange venues.

AD is an abbreviation for Serve First. That is, one more goal win will win the game.
