This is a chess tournament in Mondariz Balneario, Spain, in 2026. Players will compete in one open section with a classical time control and a Sub-2400 tournament profile.

The event combines rated chess, a compact holiday-weekend schedule, hotel-based playing conditions, and €2,330 in confirmed cash prizes. In addition, players can request byes during the early rounds.

♟️ Event Details

⏱️ Time Control & Pairings

Players receive 60 minutes for the game, plus a 30-second increment per move. This time control applies to all eight rounds.

The tournament uses a Swiss system with computerized pairings through Vega. In addition, the event counts for FIDE Elo rating.

Tie-breaks will be drawn after the last game of the final round. The possible tie-break systems are Buchholz Total FIDE, Buchholz -1 FIDE, and Progressive Score. If a tie still remains, the final ranking may be decided by drawing lots.

Players may request up to three half-point byes before Round 7. They must send bye requests by email. For Round 1, the request must arrive before the registration deadline and must receive organizer confirmation.

Players may not agree to a draw before move 30 without arbiter approval. Also, a player loses by default after arriving more than 30 minutes late.

💰 Prize Fund

The confirmed cash prize fund totals €2,330, which equals approximately USD 2,715. The prize list also includes trophies, free entries for the 2027 edition, and Chess Openings PROMASTER subscriptions.

Prize Fund Overview

General Prizes

Special Prizes

Cash prizes are not divisible or cumulative. If a player qualifies for several equal-value prizes, the organizer applies this priority order: general prizes, Elo-band prizes, veteran prize, and then age prizes from older to younger categories.

Players must attend the closing ceremony to claim cash prizes. Legal tax deductions may apply.

🧩 Sections / Groups

The tournament has one open section. All players compete in the same 8-round field.

The Sub-2400 profile makes the event especially suitable for club players and improving players who want FIDE-rated games. Moreover, the rating-band prizes give players from several Elo levels clear competitive targets.

The tournament also includes youth and veteran prize categories. Therefore, the event can attract juniors, adult club players, and experienced senior players in the same playing hall.

📅 Schedule

Players should plan carefully for the evening rounds on December 5, 6, and 7. In addition, they should arrive early for Round 8 because the final round starts in the morning.

📝 Registration

Players should register before the deadline and provide complete personal and rating information. In addition, they should pay the entry fee before the end of Round 1 to remain paired for the next round.
