Description of the Algebraic System

 

E1. Each piece is indicated by the first letter, a capital letter, of its name. Example: K = king, Q = queen, R = rook, B = bishop, N = knight. (In the case of the knight, for the sake of convenience, N is used.)

 

E2. For the first letter of the name of a piece, each player is free to use the first letter of the name which is commonly used in his country. Examples: F = fou (French for bishop), L = loper (Dutch for bishop). In printed periodicals, the use of figurines for the pieces is recommended.

 

E3. Pawns are not indicated by their first letter, but are recognized by the absence of such a letter. Examples: e5, d4, a5.

 

E4. The eight files (from left to right for White and from right to left for Black) are indicated by the small letters, a, b, c, d, e, f, g and h, respectively.

 

E5. The eight ranks (from bottom to top for White and from top to bottom for Black) are numbered 1, 2, 3, 4, 5, 6, 7 and 8, respectively. Consequently, in the initial position the white pieces and pawns are placed on the first and second ranks; the black pieces and pawns on the eighth and seventh ranks.

 

E6. As a consequence of the previous rules, each of the sixty four squares is invariably indicated by a unique combination of a letter and a number.

 

E7. Each move of a piece is indicated by (a) the first letter of the name of the piece in question and (b) the square of arrival. There is no hyphen between (a) and (b). Examples: Be5, Nf3, Rd1. In the case of pawns, only the square of arrival is indicated. Examples: e5, d4, a5.

 

E8. When a piece makes a capture, an x is inserted between

 

(a) the first letter of the name of the piece in question and

(b) the square of arrival.

Examples: Bxe5, Nxf3, Rxd1.

When a pawn makes a capture, not only the square of arrival but also the file of departure must be indicated, followed by an x. Examples: dxe5, gxf3, axb5. In the case of an "en passant" capture, the square of arrival is given as the square on which the capturing pawn finally rests and "e.p." is appended to the notation.

 

E9. If two identical pieces can move to the same square, the piece that is moved is indicated as follows:

(1) If both pieces are on the same rank: by

(a) the first letter of the name of the piece,

(b) the rank of the square of departure, and

(c) the square of arrival.

(2) If both pieces are on the same file: by

(a) the first letter of the name of the piece,

(b) the rank of the square of departure, and

(c) the square of arrival.

(3) If the pieces are on different ranks and files, method (1) is preferred. In the case of capture, an x must be inserted between (b) and (c).

Examples:

(1) There are two knights, on the squares g1 and d2, and one of them moves to the square f3: either Ngf3 or Ndf3, as the case may be.

(2) There are two knights, on the squares g5 and g1, and one of them moves to the square f3: either N5f3 or N1f3, as the case may be.

(3) There are two knights, on the squares h2 and d4, and one of them moves to the square f3: either Nhf3 or Ndf3, as the case may be.

If a capture takes place on the square f3, the previous examples are changed by the insertion of an x:

(1) either Ngxf3 or Ndxf3,

(2) either N5xf3 or N1xf3,

(3) either Nhxf3 or Ndxf3, as the case may be.

 

E10. If two pawns can capture the same piece or pawn of the opponent, the pawn that is moved is indicated by

(a) the letter of the file of departure,

(b) an x,

(c) the square of arrival.

Example: If there are white pawns on squares c4 and e4 and a black pawn or piece on the square d5, the notation for White's move is either cxd5 or exd5, as the case may be.

 

E11. In the case of the promotion of a pawn, the actual pawn move is indicated, followed immediately by the first letter of the new piece. Examples: d8Q, f8N, b1B, g1R.
