In tennis, players can compete in pairs, commonly referred to as "doubles." In this format, two teams of two players each work together to win points and games. Doubles matches require unique strategies compared to singles, emphasizing teamwork, positioning, and communication. Players must coordinate their movements and shots effectively to cover the court as a unit. Doubles is popular in both recreational and professional tennis, featuring its own tournaments alongside singles events, including at the Grand Slam level, where teams compete for prestigious titles.
