0 the score in tennis when both players have 40 points -- （网球赛中的）平局（即双方均得40分）
What the deuce do you think you're doing? 你认为自己到底在干什么？
They had the deuce of a time.
I call that roughly deuce.
If the player with advantage loses the next point, the score is again deuce, since the score is tied.
In this way, the sum of the scores is even when the server serves from the deuce court.
The first of each two-point sequence starts from the server's advantage court and the second starts from the deuce court.
High-low split games with deuce-to-seven low are usually played with a declaration.
From this point on, whenever the score is tied, it is described as deuce regardless of how many points have been played.
When he looks at the deuce he thinks of how many suits he'd own if he owned two more than he owns now.
