🏁 Event Details

The event details above reflect the tournament structure, venue, organizer, playing format, and prize package for the 2026 edition.

⏱️ Time Control & Pairings

The tournament uses a classical chess time control of 90 minutes for the full game with a 30-second increment from move one. Pairings follow the FIDE Dutch Swiss System across nine rounds, and the organizers use Vega for pairings and standings. Consequently, players get a full week of meaningful classical games and a clear competitive structure.

Initial ranking follows this order: FIDE standard rating, FIDE rapid rating, FIDE blitz rating, URS, and then alphabetical order. Moreover, players may request up to two half-point byes before the tournament starts, although they cannot use them in the last four rounds. If a player misses a round without a bye request, the player may still ask the arbiter not to pair them and receive zero points for that round.

The tournament applies a 30-minute default time for forfeits. If players finish on the same score, the event uses Buchholz FIDE -1, Buchholz FIDE total, Sonneborn-Berger, progressive-cumulative score, average rating of opponents, and finally drawing of lots.

🏆 Prize Fund

Open Internacional de Ajedrez Ciudad de Oviedo 2026 offers EUR 7,230 in confirmed cash prizes. The general standings provide the largest cash awards, while the Elo sections add extra prize opportunities for players below 2200 and below 1900 FIDE. Therefore, the event rewards both top overall performance and strong results inside key rating bands.

The event also gives non-cash prizes in the women’s classification and in age categories. However, cash prizes do not accumulate, and a player receives only the highest-value eligible prize.

♟️ Sections / Groups

The tournament does not split the field into multiple playing groups. Instead, all accepted players compete in one main open, which keeps the format simple and the final standings easy to follow.
