📌 Event Details

⏱️ Time Control & Pairings

The organizer runs the tournament over nine rounds using the Dutch Swiss system. Moreover, Swiss-Manager handles the pairings and tournament administration.

Each player receives 90 minutes for the game. In addition, the clock adds 30 seconds after every move from move one.

The organizer ranks players first by FIDE rating. However, it uses FADA rating when a player has no FIDE rating.

A player who misses a round without a justified reason leaves the tournament. Therefore, players must notify the arbiters before any planned absence.

🏆 Prize Fund

The organizer offers a total prize fund of €15,000, approximately $17,070. Moreover, the prize list includes general, women’s, rating-band, and Aragon federation awards.

Prizes and trophies do not accumulate. Therefore, the organizer applies this priority: general, women’s, rating-band, and Aragon awards.
