How does the scoring system work in a game of 40-40 tennis?

Answer 1

In a game of 40-40 tennis, also known as deuce, the scoring system works as follows: When both players have a score of 40, the game is tied and the next point determines who wins the game. The player who scores the next point after deuce will have the advantage, and if they win the next point as well, they win the game. If the player with the advantage loses the next point, the score goes back to deuce until one player wins by two points.
