Braille chess notation

Braille chess notation adapts written game information to braille cells, patterns of raised dots read by touch. It allows a blind reader to record, consult, and edit chess content without relying on a visual representation.

The code specifies how to write piece identifiers, squares, move numbers, captures, checks, promotions, results, and other elements. It also defines spacing and layout so that a sequence can be read unambiguously. The task is not always a one-for-one substitution of printed characters because some braille signs act as indicators that change how following cells are interpreted.

The code can transcribe algebraic notation, in which a square is named by a file letter and rank number, but it uses its own braille conventions. Edition, language, and transcription authority matter, so a document should apply one declared standard consistently.

The FIDE Laws permit a visually disabled player to keep score in braille, longhand, or on a recording device. The notation code does not replace a tactile board or change the rules of chess; it solves the separate problem of representing information.
