Yes pardeep ji correct its a situationn when both have same oints 6-6 n now they have to colect two points together

At a score of 6-6, a set is often determined by one more game called a "seven point tiebreak." Points are counted using ordinary numbering. The set is decided by the player who wins at least seven points in the tiebreak but also has two points more than his opponent. For example, if the score is 6 points to 5 points and the player with 6 points wins the next point, he wins the tiebreak and the set. If the player with 5 points wins the point, the tiebreak continues and cannot be won on the next point, since no player will be two points better than his opponent. Since only one more game is played to determine the winner of the set, the score of the set is always 7-6 (or 6-7). Sometimes the tiebreak points are also included, for example 7-6 (7-4). Another way of listing the score of the tiebreak is to just list the loser's points. For example, if the score is listed as 7-6 (8), the tiebreak score was 10-8 (since 8 is the loser's points, and the winner must win by two points) ...more
