Appendix E: Algebraic notation
FIDE recognizes for its own tournaments and matches only one system of notation, the Algebraic System, and recommends the use of this uniform chess notation also for chess literature and periodicals. Scoresheets using a notation system other than algebraic may not be used as evidence in cases where normally the scoresheet of a player is used for that purpose. An arbiter who observes that a player is using a notation system other than the algebraic should warn the player about this requirement.
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.)
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.
Pawns are not indicated by their first letter, but are recognised by the
absence of such a letter.
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.
Each move of a piece is indicated by
When a piece makes a capture, an x
is inserted between
E9. If two identical pieces can move to the same square, the piece that is moved is indicated as follows:
There are two knights, on the squares g1 and e1, and one of them moves to the square f3: either Ngf3 or Nef3, as the case may be.
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.
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:
If two pawns can capture the same piece or pawn of the opponent, the pawn
that is moved is indicated by
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.
E12. The offer of a draw shall be marked as (=).
