premise: The British Chess Variants Society (or BCVS) was an association of chess variant players and developers active between 1997 and 2010. The Society took over publication of "Variant Chess", a chess variant magazine which had been published since 1990; the magazine ceased publication with the dissolution of the Society.
hypothesis: The British Chess Variants Society is sometimes abbreviated as BBVS.
reason: The system did not pay close enough attention to the fact that the abbreviation is wrong.
