When do you play a 12 point tie-breaker?

A 12-point tie-breaker is typically played in tennis when the score in a set reaches 6-6. In this format, players compete to be the first to reach 7 points, but they must win by at least 2 points. If the score reaches 6-6 in the tie-breaker itself, it continues until one player achieves a 2-point lead. This format is often used in certain tournaments to expedite play and ensure matches conclude in a timely manner.
