When shopping for a tennis racquet, decide whether you are looking for a pre-strung racquet or an unstrung racquet. Pre-strung tennis racquets are a good choice for most beginner and intermediate players, as they are highly versatile and allow you to focus on the fundamentals without added complexity. Advanced players often prefer an unstrung racquet, which allows them to tailor the string type and tension to their swing and playing style.
If the score is tied at 40 ("40-all"), that is "deuce," which is essentially another word for tie. To break the tie, someone must win two points in a row. If you are serving at deuce and you win the next point, then you say "my ad," which means "my advantage." If your opponent wins, it goes back to deuce, and someone again must win by two points in a row. Yes, this could go on forever.

The impetus to use some kind of a tie-breaking procedure gained force after a monumental 1969 struggle at Wimbledon between Pancho Gonzales and Charlie Pasarell. This was a 5-set match that lasted five hours and 12 minutes and took 2 days to complete. In the fifth set the 41-year-old Gonzales won all seven match points that Pasarell had against him, twice coming back from 0–40 deficits. The final score was 22–24, 1–6, 16–14, 6–3, 11–9 for Gonzales.

Tennis is a racket sport that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to maneuver the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will.
