It is when you have a scoring of 40-40, THAT is called a DUECE.
In tennis, it means the score is tied.
40 - 40
An advantage out (or ad. out, when you call the score) is when youe oppenent has won the first point of duece (40-40.) Ad. in, is when you win the first point of duece.
You begin play by serving from the Right Side of the Court (known as the duece court) serving to the left.
Duece is 40-40, and then if you play an add game, it turns into add-out or add-in:)
duece is 14 year old
ADV stands for 'advantage'. ADV is used when a player scores a point when the score is at duece. The player has the 'advantage' because if they win the next point, they win the game. If the player who has the advantage loses the next point, the score goes back to duece.
Love is 0. 15 is next, then 30, then 40, and if you have 40-40(duece) then there's advantage front or back team.
the deuce side is the right half of the court. called the deuce side because when the score is deuce, the server serves from the right side of the baseline
