FIDE Arbiters’ Manual 2021

FIDE Arbiters’ Manual 2021 published

Last summer, the Arbiters’ Commission invited the chess community to provide feedback and contribute with ideas to improve the FIDE Arbiters’ Manual, a key working tool for chess arbiters worldwide. The result of this team effort is the 2021 edition of the FIDE Arbiters’ Manual that was published a few days ago, in which more people contributed than ever before.

Apart from many of these suggestions, this important document was also enlarged and is now composed of 14 chapters. The two new ones are #13, with the FIDE Online Chess Regulations, and #14, with sample exam questions for FIDE arbiters.

The document also now includes more educational content, like a section by Professor Ken Regan about his Anti-cheating tool, and more comments and interpretations written by experienced arbiters.

The topics have also been rearranged in a different order that better reflects their importance:

1. Governing play: Roles and duties, Laws of Chess, Anti-Cheating, Pairings
2. Players’ focus: Ratings and norms
3. Technical references: Tournaments and tie-breaks
4. Administrative: titles and classifications of arbiters, application forms

The International Arbiter Shohreh Bayat, Councillor of the ARB Commission, was the leader of the project, and she expressed her gratitude to all those who contributed. in particular, Alex McFarlane, Ken Regan, Juergen Klueners, David Sedgwick, Aris Marghetis, Gopakumar MS, Shaun Press, Sabrina de San Vicente, Alex Holowczak, Anantharam Rathinam, Hal Bond, Igor Vereshchagin, and Pierre Denommee. They all provided very valuable input.


The Arbiters’ Manual is an ongoing project, so any feedback, comments, and proposals to continue improving it are welcome any time. Feel free to address them to the ARB Commission using their contact email:
