Duece: A market in Tennis

Tennis has a different point system than most sports.  In tennis, "deuce" occurs when both players have a score of 40-40 in a game. At this point, a player must win two consecutive points to win the game. The scoring process after deuce is:

1. If the server wins the next point, they get an advantage (Ad-In).
2. If the receiver wins the next point, they get an advantage (Ad-Out).
3. If the player with advantage wins the next point, they win the game.
4. If the player with advantage loses the next point, the score returns to deuce, and the process repeats.

This cycle continues until one player wins two points in a row after deuce.

Here's a pictorial example of "Deuce" in tennis. It shows a tennis court with a scoreboard displaying 40-40, two players in position, and an umpire overseeing the match. Let me know if you need any modifications! 🎾
