Here is the full Tennis Challenge puzzle:

Alice, an amateur tennis player, has just joined a tennis club. As a welcome, the head coach Jenny decided to give her a challenge - Alice will play 3 games against Jenny and another club member Carla alternatively, and she needs to win two consecutive games to win the challenge. The coach allowed Alice to pick the order in which she would like to play those games - either Jenny-Carla-Jenny, or Carla-Jenny-Carla. Everyone knows that the coach is the best player in the club.

Which order should Alice choose?
