when is a tie break used in tennis
Tennis scoring system A set is won by the first side to win 6 games, with a margin of at least 2 games over the other side (e.g. 6–3 or 7–5). There is usually a tie-break if the set is tied at six games per player.
Table tennis racket Table tennis regulations approved by the International Table Tennis Federation (ITTF) allow different surfaces on each side of the paddle for various amounts of spin (including nullifying it) or speed.[1] For example, a player may have a spin-heavy rubber on one side of his paddle, and no spin on the other side. The player can flip the racket in play for different types of returns. To help a player distinguish between different types of rubber used by his opponent, regulations specify that one side of a paddle must be red while the other must be black, allowing a player to see what side of a paddle hits the ball mid-play. The player has the right to inspect his opponent's racquet before a match to see the type and color. Current rules state that, unless damaged in play, the paddle cannot be exchanged for another at any time during a match.[2]
