Advantage scoring, where deuce, ad-in, and ad-out are in use, is the standard for competitive tennis, including the pro tour. However, in practice or recreational tennis, players will sometimes forego ad scoring and play games that we refer to as no-ad scoring or sudden death.
In context|tennis|lang=en terms the difference between deuce and advantage is that deuce is (tennis) a tie, both players have the same number of points and one can win by scoring two additional points while advantage is (tennis) the score where one player wins a point after deuce but needs the next too to carry the game.
Answer (1 of 3): Advantage and deuce are type of score procedure in a lawn tennis game. In a tennis game a player has to win 4 points (not consecutively) in order to win a game against his opponent. But if both the opponents are able to win 3 points on the stretch together, then in order to win...
When the two players have reached a score of deuce, one player must then win two consecutive points for the game to conclude. At this point, advantage scoring is introduced. If the player who is serving wins the next point after the two players reach deuce, then that player holds the advantage.
This type of tennis scoring is known as "advantage scoring" (or "ads"). The side which wins the next point after deuce is said to have the advantage. If they lose the next point, the score is again deuce, since the score is tied. If the side with the advantage wins the next point, that side has won the game, since they have a lead of two points.
Here ad court (Advantage Court) and deuce court are the two tennis terms that are used in case of deuce situation. Ad court is usually considered as a left side of the player and the deuce court is considered as the right side of the tennis player who is serving when it is deuce.
Consider a game of tennis where there is no "deuce / advantage" and the first player to score four points wins the game. Suppose player A wins each point independently with probability p and B wins with probability q=1-p. Suppose that player B won the first two points, so now B needs 2 points to win and A still needs 4 points.
A player has to score two consecutive points to win the game following deuce. The first point scored after deuce is known as "advantage." Once a player scores advantage, their next point wins.
