What is deuce in tennis?
At deuce, the next point gives one player advantage. If they win the following point too, they win the game. If they lose it, the score goes back to deuce.
In no-ad scoring, used in most professional doubles, there is no advantage: the point at deuce decides the game.
In a match
Deuce, advantage server, deuce, advantage receiver, game receiver: a break of serve after two deuces.
