The 3rd IRT Sub-2200 A.D.U.M. 2026 — Mar del Plata FIDE Classical takes place on December 18–20, 2026, at the A.D.U.M. headquarters on General Roca 3865 in Mar del Plata, Argentina. Federación Marplatense de Ajedrez administers this international rating event at the Agremiación Docente Universitaria Marplatense facilities.

Players compete in seven Swiss-system rounds with 60 minutes plus a 30-second increment per move. The tournament counts toward the FIDE Standard rating list and is advertised as an Under-2200 event. Consequently, players near the rating ceiling should confirm their eligibility under the organizer’s current rules before entering.

The program includes two Friday rounds, three Saturday rounds and two final games on Sunday. The announced entry fee is ARS 40,000. In addition, the official tournament record provides the current starting list, arbiter details and round-by-round start times.

📌 Event Details

⏱️ Time Control & Pairings

The competition is one seven-round Swiss-system event, administered through Swiss-Manager. Each player receives 60 minutes for the game, with 30 seconds added after every move. The increment applies from the start, so lengthy endgames may extend play beyond the initial time allowance.

The event carries the Sub-2200 designation and counts for FIDE Standard ratings. All entrants belong to the same playing field rather than separate age or rating sections. However, the applicable rating list and any eligibility exceptions are determined by the organizer’s 2026 entry conditions.

Tournament officials are Fabián Delicio (director), Leandro Mario Cardoso (chief arbiter) and Juan Ignacio Cuello Alcaria (deputy chief arbiter). Players should check that their names, federation and ratings are correctly recorded before the opening pairing.

📅 Schedule

All seven rounds have confirmed start times in the official Chess-Results program. The table uses Mar del Plata local time (UTC−3) and short date labels so it fits more comfortably on mobile devices.

Saturday has three scheduled rounds, making it the most intensive playing day. Moreover, the final round begins on Sunday at 2:00 PM, so competitors planning an evening departure should allow time for the full game and any post-event formalities.
