Betza's funny notation ones. The notation is based on dividing moves that can be made on a board of squares into groups of symmetry-equivalent moves, the moves within a group differing only in the direction in which the step is taken. Each such group (referred to as "atom") is indicated by a capital, such as N for the 8 moves of the knight. The letter that represents the atom is usually the first letter of the simplest piece from current or historic chess variants that has this move, such as A and F for the alfil and ferz of shatranj (ancient Arabic/Persian chess).
Algebraic notation (chess) Philipp Stamma. Stamma used the modern names of the squares, but he used "p" for pawn moves and the original of a piece ("a" through "h") instead of the initial letter of the piece name. This article describes standard algebraic notation (SAN) required by FIDE. Each square of the chessboard is identified by a unique coordinate pair—a letter and a number. The vertical columns of squares, called ', are labeled "a" through "h" from White's left (the ) to right (the ). The horizontal rows of squares, called ', are numbered "1" to "8" starting from White's side of the
