The official version of the rules for the British Go Championship, the British Pair Go Championship and the British Youth Championships is the BGA Championships Rules page.
The BGA underwrites the costs of running the above championship events, including prizes, using sponsorship money when possible. Entry fees will be set at a realistic level.
The system of qualifying as BGA representative at various overseas championships is described in the BGA Championships Rules. The BGA web site holds Lists of past BGA representatives at international tournaments, and describes the entry criteria for each international tournament to which we send representatives.
The BGA will not normally pay the expenses of those representing us overseas.
