Spend a full summer chess weekend at the HSG Open 2026 on June 19-21, 2026 in Hilversum, Netherlands, where the organizers combine a large open atmosphere with serious Swiss-system competition. You will play six rounds across four rating-based groups, and the tournament processes ratings for both FIDE and KNSB where applicable. The event welcomes a broad field and targets players who want an efficient weekend schedule, clear section guidance, and a professional playing environment inside a hotel venue.

The tournament returns to Amrâth Hotel Lapershoek and plans to welcome more than 300 players across Groups A–D. You can also pair the main event with official side activities in Hilversum during the same week, including a youth tournament, a pub tournament, a youth clinic, and a Dudok architecture walk. If you want a well-organized open with strong weekend rhythm, clear rules, and a meaningful prize list, this tournament delivers a focused competitive experience.

🗓️ Event Details

🏆 Prize Fund

Prize amounts depend on the number of participants. The tournament shares cash prizes among tied players. If a player qualifies for multiple cash prizes, the tournament awards only the highest-value prize. The tournament adjusts payouts to avoid splitting prizes into shares below €10 per player by applying the published tie-break order until each share reaches at least €10.

Group A (cash prizes)

Group B (cash prizes)

Group C (cash prizes)

Group D (cash prizes)

⏱️ Time Control & Pairings

The tournament runs a 6-round Swiss system and seeds every round by rating. Group A and Group B use FIDE rating for pairings, while Group C and Group D use KNSB rating for pairings. The tournament locks final tournament ratings from the June 1 lists, and rating changes can move a player to a different group.

Each game uses 1 hour 50 minutes per player per game plus a 10-second increment from move 1. A player forfeits after arriving more than 60 minutes late, unless the arbiter decides otherwise. The tournament ranks players by score, then head-to-head when possible and only for first place, then opposition points, Sonneborn-Berger score, and drawing of lots. The tournament can award one half-point bye only once, only in rounds 1–4, and only when the player notifies the tournament director on time; all other byes score 0 points. In rounds 1 and 2, the tournament can re-pair a player who still has no opponent 30 minutes after the round starts, at the tournament director’s discretion.
