FIDE reminds organizers and arbiters of updated Swiss Rules effective from February 1, 2026

FIDE wishes to remind organizers, arbiters, players and Swiss pairing software providers that the updated FIDE Swiss Rules came into effect on February 1, 2026.

The revised provisions are now reflected in the FIDE Handbook and apply to all relevant tournaments and pairing procedures conducted under FIDE regulations.

The update incorporates important amendments to the Basic Rules for Swiss Systems (C.04.1) and the FIDE (Dutch) System (C.04.3), together with related adjustments to the broader Swiss Rules framework. These changes were introduced to improve clarity, simplify application, and strengthen consistency in the implementation of Swiss pairing rules.

Among the main developments are refinements to pairing procedures, clarifications regarding the handling of byes, and structural improvements intended to support arbiters and endorsed pairing software in the correct application of the rules.

FIDE also draws attention to related regulatory changes that came into effect on March 1, 2026, including updates to C.02. Chess Equipment Technical Specifications, Rules, and Regulations and 07. Play-Off and Tie-Break Regulations. Organizers and arbiters are encouraged to consult these updated texts alongside the revised Swiss Rules to ensure full compliance with the current FIDE Handbook.

These updates form part of FIDE’s continuing work to maintain clear, practical and modern regulations for tournament administration and fair competition.
