algebraic notation is similar to short algebraic notation but omits the indicators for capture ("x"), en passant capture ("e.p."), check ("+") and checkmate ("#"). It was used by Chess Informant. Figurine algebraic notation replaces the letter that stands for a piece by its symbol, e.g., ♞c6 instead of Nc6 or ♖xg4 instead of Rxg4. Pawns are omitted as in standard algebraic notation. This style is widely used in chess literature to allow the moves to be read independent of language. To display or print these symbols on a computer, one or more fonts with good Unicode support must be installed, and the document (web page, word processor document, etc.) must use one of these fonts. For more information see Chess symbols in Unicode. Reversible algebraic notation is based on long algebraic notation, but adds an additional letter for the piece that was captured, if any. The move can be reversed by moving the piece to its original square, and restoring the captured piece. For example, Rd2xBd6. Concise reversible algebraic notation is similar to reversible algebraic notation, but omits the file or rank if it is not needed to disambiguate the move. For example, Rd2xB6. This notation is recommended by Gene Milener in Play Stronger Chess by Examining Chess 960: Usable Strategies for Fischer Random Chess Discovered. Figurine concise reversible algebraic notation is a form of concise reversible algebraic notation with non-Staunton figurines, used by Gene Milener during Chess960 tournaments. Descriptive notation was the prevalent notation in English-speaking countries until the late 1970s. In this system, files are named after the piece that is initially on the back rank, and each square has two names depending on whether it is from White's or Black's point of view. This is still used by a dwindling number of mainly older players, and knowledge of descriptive notation is necessary to study older chess books. Similar systems were used in other languages, including Spanish and French. ICCF numeric notation. In international correspondence chess the use of algebraic notation may cause confusion, since different languages have different names for the pieces. The standard for transmitting moves in this form of chess is ICCF numeric notation. Smith notation is a straightforward chess notation designed to be reversible and represent any move without ambiguity. The notation encodes the source square, destination square, and what piece was captured, if any. Coordinate notation is similar to algebraic notation except that
