ABSTRACT:
As a substitute from opaque plastic of choice for the construction material of a tennis racket, use instead is made of a clear plastic that viewed from afar, such as from one base line to the other, prevents the opponent of the user of the clear plastic racket from visibly detecting a racket position as might enable the opponent to anticipate the shot to be executed by the user, to thereby contribute to the strategic playing value of the tennis racket.
