Notation

In algebraic notation, each square has a unique name based on it's file and rank: 'a1' through 'a8' and so on to 'h1' through 'h8'.

Since the gameplay occurs in turns, no player information is recorded - because white always moves first you know that the first move recorded is for white, the second is for black, etc.

Piece types

Each piece has a name based on the type of piece it is:

  • p » pawn (although the piece type 'p' is not recorded)
  • R » Rook
  • N » Knight (written using an 'N' to differentiate it from the King)
  • B » Bishop
  • C » Cardinal *G piece only in Ry::GrandChess
  • M » Marshall *G piece only in Ry::GrandChess
  • Q » Queen
  • K » King

Movement

When a piece moves usually only the "to" square is recorded along with the piece type (execpt for pawns):

  • e4 » pawn to square 'e4' (pawn types aren't recorded)
  • Ra5 » Rook to square 'a5'
  • Nb3 » Knight to square 'b3'
  • Bh7 » Bishop to square 'h7'
  • Qg6 » Queen to square 'g6'
  • Kc8 » King to square 'c8'

Capturing

When your piece captures an opponent's piece an 'x' is recorded before the "to" square. If the piece moved is a pawn then the pawn's rank is recorded before the "x" (only the rank is needed since pawns attack diagonally and not vertically):

  • cxb5 » pawn from 'c' takes piece at 'b5'
  • Rxa5 » Rook takes piece at 'a5'
  • Nxb3 » Knight takes piece at 'b3'
  • Bxh7 » Bishop takes piece at 'h7'
  • Qxg6 » Queen takes piece at 'g6'
  • Kxc8 » King takes piece at 'c8'

Multiple possible moves

If two pieces of the same type may move to the same square then a portion of the "from" square is recorded to differentiate the piece moved: if the rank of the piece moved is more descriptive then it is used, if the file is more descriptive then it is used. For example, if you have a Rook at 'a1' and a Rook at 'c5', they may both attack the opponent at 'a5' (the Rook at 'a1' moving vertically, the Rook at 'c5' moving horizontally). The notation below represents how the move will be recorded depending on which Rook you move:

  • Rcxa5 » Rook from 'c5' takes piece at 'a5'
  • R1xa5 » Rook from 'a1' takes piece at 'a5'

Check and Checkmate

If you make a move which places your opponent in check it is recorded with a plus sign "+" added to the end of the move record. Checkmate is recorded with two plus signs "++".

  • Ra5+ » Rook to 'a5', check
  • Ra5++ » Rook to 'a5', checkmate
  • Nb3+ » Knight to 'b3', check
  • Nb3++ » Knight to 'b3', checkmate

Castling

Castling is denoted depending on whether the move was a King's side castle or a Queen's side castle:

  • 0-0 » King's side castle
  • 0-0-0 » Queen's side castle

En Passant

Pawns capturing en passant are denoted as normal with the addition of an 'x' (capture) and 'ep' (en passant) added to the end of the move record:

  • cxb6ep » pawn from 'c' takes pawn at 'b5' en passant
  • cxb3ep » pawn from 'c' takes pawn at 'b4' en passant

Promotion

If a pawn makes it to the other side of the board and is promoted, the move is recorded normally with the addition of the piece type it is promoted to:

  • cb8/Q » pawn from 'c' to 'b8', promoting to Queen
  • cxb8/N » pawn from 'c' takes pawn at 'b8', promoting to Knight

Win

A win is recorded using a 1 and a 0 based on which player won. White is recorded first, black second:

  • 1-0 » white wins
  • 0-1 » black wins
  • 1-1 » draw game
