Championship Rules Changes: History

These were the rules in force in various years. The rules currently in force are slightly different.

In December 2021, the sections on eligibility (A2 and F5) were amended to clarify the passport and residence requirements, and to reduce the residence requirements for junior players.

The rules were amended for the 2020 Championship to remove the Challengers' League stage.

In 2008 AGA Rules were adopted.

Until 2006 the Champion did not need to play the Challengers' League and also some of the best players did not play the Candidates'. Since 2000 qualifying was based on the number of wins at certain levels in British tournaments, rather than achieved rating after events as in the new system.

For reference, some old versions of the rules and pages detailing changes have been preserved:

• 2020 version of the rules In 2020 the Challengers' League was abolished.
• 2019 version of the rules In 2019 the defeated Challenger of the previous year (as well as the Champion) was given automatic entry direct to the Challengers' League. Fischer time was to be used unless digital clocks are unavailable.
• In 2016 the 5 years residence qualification date was changed.
• In 2014 the title match was made optionally 3 or 5 games.
