How does a deuce work in tennis?

Answer 1

A deuce occurs when both players have earned three points in one game, making the score 40-40. When this happens, the game turns into a 'win by two' situation. First player to get up by two points takes the game. Say we are playing a match and I win the first point. As we go to serve the next point, the score is considered to be my ad. If you win the next point, the score goes back to deuce. If i win it, I receive the game.
