  abstract = {In the setting of contract theory, retractable contracts have been
              defined to formalize binary session protocols where the partners
              can go back to certain particular synchronization points when the
              session gets stuck, looking for a successful state, if any. In the
              present paper we propose a three-party game-theoretic
              interpretation of client/server systems of retractable contracts.
              In particular, we show that a client is retractable-compliant with
              a server if and only if there exists a winning strategy for a
              particular player in a game-theoretic model of contracts. Such a
              player can be looked at as a mediator, driving the choices in the
              retractable points. We show that winning strategies for the
              mediator player correspond to orchestrators in a system of
              orchestrated client/server sessions, and vice versa.},
