Federación Marplatense de Ajedrez

Federación Marplatense de Ajedrez is an Argentine chess organization associated with organized competitions and chess development in Mar del Plata, Buenos Aires Province. Its tournament activities include nationally and internationally rated events, local competitive chess and the coordination of official over-the-board competition records. Its name appears as the creator and tournament-data publisher for the December 2026 3rd IRT Under 2200 A.D.U.M. event in the international Chess-Results database.

The Mar del Plata chess community includes clubs, teaching programs, junior chess, open tournaments and chess activities hosted by educational and cultural institutions. The federation works within this environment to provide competition opportunities for players of different ages and ratings. Event administration involves publication of starting lists, pairing information, tournament schedules and results so that participants can verify the accuracy of their competition records.

One example is the 3rd IRT Sub-2200 A.D.U.M. 2026, scheduled for December 18–20 at the headquarters of the Agremiación Docente Universitaria Marplatense at General Roca 3865. The tournament uses seven Swiss rounds and the standard international time control of 60 minutes plus 30 seconds per move. Its Under 2200 designation makes it a rating-restricted event for players seeking FIDE Standard competition.

The event's record identifies Fabián Delicio as Tournament Director, Leandro Mario Cardoso as Chief Arbiter and Juan Ignacio Cuello Alcaria as Deputy Arbiter. The organizer provides two published contact numbers for tournament registration and information. Chess-Results displays the edition-specific list of competitors, including their national federation, rating and FIDE records; subsequent pairings and results are administered through Swiss-Manager.

The playing location at A.D.U.M. also reflects the relationship between local chess and community institutions in Mar del Plata. The A.D.U.M. chess subcommittee has supported classes and competitive play, while earlier editions of the IRT Under 2200 event brought competitors from the city and surrounding region. In the club's 2025 tournament, the venue hosted a seven-round international rating competition, although entry and prize rules of that past edition are not automatically valid for 2026.

Participants should check current tournament conditions against the event's official 2026 Chess-Results page and the chess news and organizer announcement website. The database provides the event's confirmed December dates, rating type and schedule. Meanwhile, A.D.U.M. is the host venue rather than an automatic substitute for the federation's tournament administration, so questions about registration or qualification should go to the listed event contacts.
