Chess

You can record a chess game using [chess]{GameScore}[/chess], where {GameScore} is the list of moves made in the game to date. You may use either Short Algebraic Notation (SAN), or the old GL-style FromSquareToSquare format. Rules of chess ARE enforced when using this tag. Use ChessVariant if you do not want rules enforced. If you simply want to display a board (for a puzzle, perhaps) you can use either the Forsyth-Edwards Notation tag, like this: [chess][FEN "<fen_string>"][/chess], or the simpler ChessBoard tag.

Basics

[chess]e4 c5 Nf3 d6 d4 cxd4 Nxd4[/chess] will display the beginning of a game. The same game can be represented [chess]e2e4 c7c5 g1f3 d7d6 d2d4 c5d4 f3d4[/chess]. Or you can mix and match and make things really confusing: [chess]Pe4 c5 g1f3 d6 Pd4 c5d4 Nfxd4[/chess]... however I always show the output in SAN (with the optional P kept if it's specified, omitted if it's not)

Notes

• Illegal moves are skipped with a note at the top of the movelist.

• Castling is made through the O-O or O-O-O commands (the 'o' letter, not zero; case is irrelevant).

• En passant is made through the command you would use as if the opponent had moved only one square. For example: [chess]e4 e6 e5 d5 exd6[/chess].

Tags

Portable Game Notation(PGN) notation is supported. Only the 7 tag roster will be displayed. The format is:

open bracket, tag, space, double quote, value, double quote, close bracket.

The seven tags that are displayed are: Event, Site, Date, Round, White, Black, and Result .

[chess][white "JEEP"][Black "Other"][site "GL"][date "2004/??/??"][Round "1"][Event "GL Tournament"][result "*"]1. e4 e5 2. d4[/chess]

would produce:

If you wish to start a game from a different starting position, you may include a tag with the Forsyth-Edwards Notation, like this:

[chess][FEN "rnbkqbnr/pppp1ppp/8/4p3/4P3/8/PPPP1PPP/RNBKQBNR"]d4 exd4[/chess]
