Lesson plan
ICCF numeric notation
ICCF numeric notation is the official chess notation system of the International Correspondence Chess Federation. The system was devised for use in international correspondence chess to avoid the potential confusion of using algebraic notation, as the chess pieces have different abbreviations depending on language. In ICCF numeric notation, each square of the chessboard has a two-digit designation. The first digit is the number of the ; files are numbered 1 to 8 from left to right from White's point of view. The second digit is the ; ranks are numbered 1 to 8 from nearest to farthest from White's point of view. Each move is denoted by either four or five digits: the first two digits denote the square the moving piece leaves; the following two digits denote the square at which the moving piece arrives; and, where applicable, the fifth digit denotes the piece of promotion. In recent years, the majority of correspondence chess games have been played on Internet servers, on which the moves are entered using a graphical interface. This, along with the near-universal acceptance of algebraic notation, has led to a decline in the use of ICCF numeric notation.
