In tennis, to “break” an opponent’s serve means to win a game while the opponent is serving, thus gaining an advantage in the match. This is considered a pivotal moment, as it disrupts the serving player's momentum and strengthens the returning player's position. Breaking serve can shift the dynamics of a match, impacting the overall confidence and strategy of both players. Typically, a break increases the likelihood of winning the set, making the ability to break serve a critical skill for competitive players. Effective strategies and consistent performance can turn these moments into match-defining achievements.
