The AGM approved the AGA-style rules with no opposition by the AGM on 5th April 2008. The statement of the Go rules used in BGA tournaments is found in Rules of Play. This document is inspired by the AGA's official statement of the rules and the BGA'S interpretation of those rules.
Tournament organisers can get an easy to digest statement of the rules in the AGA Summary to print out for display.
Players can get a crib sheet showing guidance in playing by AGA-style rules from Short Guide.
BGA referees should refer to Rules of Play for the definitive statement of BGA tournament rules of play.
