We now have a variety of chess-variant terms that have been more or less accepted by the greater chess community. There are a number of others, however, that are still being tried and tested. Perhaps sometime within the next decade, a few dozen terms will have earned the popularity they need to merit an official lexicon. This is how new terms become a part of a common language. The only problem that I have with this process is that we could use that lexicon now! It is for this reason that I have jumped the gun, so to speak, and assembled the following terms into a modest CV glossary. These terms include...
- Those most frequently used on The Chess Variant Pages.*
- Those used by D. B. Pritchard in The Encyclopedia of Chess Variants.
- Those used by Anthony Dickens in A Guide to Fairy Chess.
- Those used by Edward R. Brace in An Illustrated Dictionary of Chess.
- Those included to facilitate definitions taken from the above sources.
- Those included to satisfy an obvious need for completion.**
It is assumed that the reader is familiar with standard 8x8 chess, as its more basic terms are not included
here. Neither are the names of specific pieces, whose proper place is the Piececlopedia.
The names of specific variants are also omitted, with the exception of small shogi
and xiangqi, which have gained such a following that some believe that they
should be included under the heading of orthochess.
Please review this page and let me know if there are any terms that you object to or any key terms that
I might have overlooked. If we can agree on a basic nomenclature, we may encourage others to use it and perhaps
eliminate some of the ambiguities that plague CV submissions. Please send your comments and recommendations to
