This is probably pointless, and almost certainly frivolous, but I have been thinking about syntax to partially describe promotion lately, and have a proposal. <hr> A pieces that promotes is indicated by an <b>=</b> sign at the end of its movement description, optionally followed by a piece description (what it promotes to), a set of piece descriptions enclosed in <b>(</b> <b>)</b> and separated by commas or spaces, or a one of <b>*</b>, <b>+</b> or <b>-</b>. <blockquote> <p><b>*</b> indicates promotion to any type of nonroyal, nonpawn piece that started play on either side of the board. <p><b>+</b> indicates promotion to any type of nonroyal, nonpawn piece that started play on the owner's side of the board. <p><b>-</b> indicates promotion to any previously captured nonpawn piece. </blockquote> <p> A <b>=</b> at the end of a piece without anything else simply states that the piece promotes in some (most likely obscure) manner. If a piece can promote in different ways at different times, multiple promotion strings separated by multiple <b>=</b>'s are possible. <p> This scheme does not specify how or where promotion occurs. <h4>Examples</h4> <li><u>FIDE Pawn</u>: fnWfcF=* -or- fnWfcF=(N,B,R,RB) <p> <li><u>Makruk Pawn</u>: fnWfcF=F <p> <li><u>Gothic Isles Chess Pawn</u>: fnWfcF=FfW=- <p> <li><u>Rococo Cannon Pawn</u>: gWFnWF=- <p> <li><u>Shogi Rook</u>: R=FR </ul> <hr> So there it is. Hardly complete, but that's funny notation for you.
