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).
Shogi notation A piece that promotes is indicated with 成 following the piece's character, such as ７三桂成 (N-73+). If a piece does not promote, this is indicated with 不成 following the piece's character, such as ７三桂不成 (N-73=). There is an alternate symbol for unpromotion: 生 is sometimes used instead of 不成. Unlike western notation, numbering Japanese game records is not obligatory. Although players' moves often aren't numbered, shogi moves are always counted per player's move. This is commonly seen in checkmate problems where a "3-move" ３手 checkmate problem would mean a move sequence of black-white-black. This is unlike western chess which counts
