In tennis, a tiebreaker is used to decide the winner of a set when the score is even at 6-6. Here's how it works: 1. **The first player to reach seven points wins the tiebreak and the set**. This means that a player must win by at least two points. 2. If a player wins a point, they continue to serve for the next point until they lose a point. Then the serve switches to the other player. 3. **The player whose turn it was to serve in the set serves the first point of the tiebreak**. After that, the serve alternates between players every two points. 4. If the score reaches six-points-all, the winner of the tiebreak is the first player to win two points in a row, not just the first to reach seven. So, in essence, the tiebreak is a race to seven points with a two-point advantage, and it's played in a rotating serve format starting with the player who was due to serve first in the set. read more >>
