I am a psychologist

I am a psychologist and I help people survive. Do you want to participate in a psychological and social experiment?. Imagine you are betting to save your life or lose your life over a tennis match. One player is going to play on your behalf. The player who is playing on your behalf doesn’t know he is playing to save your life. If the player loses the tennis match you lose your life and if the player wins the match you save your life. The surface of the tennis court is randomly either grass, clay or hard court. The roll of a dice determines the surface with the same chances to be any of the 3. At their peak, which player would you choose to play for you to save your life?. Thank you.
