Backcourt
 The back half of the court between the service
 and baseline. This zone is a taboo zone also
 known as "no man's land."

 Backhand
 A ground stroke hit on the left of the body by
 right-handed players, and on the right of the
 body by left-handers.

 Baseline
 The line at the end of the court.

 Baseline rally
 A rally where both players repeatedly
 exchange shots from their respective
 baselines.

 Baseline tennis
 A tactical approach whereby players remain at
 the baseline and attempt to wear their
 opponents down through long rallies, or -
 should the opportunity arise - to win the point
 with a passing shot.

 Best of three (or five)
 Refers to the maximum number of sets in any
 match. In "best of three" matches, players
 need to win two of the three sets. In men's
 tennis, most matches are "best of five," i.e. a
 match finishes when a player has won three
 sets.

 Big point
 A crucial point deciding which player wins a
 set or an important game. For example, when
 the scores are level and the server is 30-40
 down.

 Break (of service)
 Where the serving player loses the game.

 Breakback
 Situation where a player who has lost his or
 her service succeeds in winning the
 opponent's service game, usually leveling the
 scores.

 Bye
 Free passage into the second round of a
 tournament. Players may be given a bye if a
 tournament doesn't have enough players (e.g.
 if there are only 28 players in a tournament
 designed for 32, there will be 4 byes in the first
 round). Byes are always awarded to seeded
 players.
