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).
Fairy chess piece from e4 to f5 (first the ferz move) then g5, h4, h3, g2, f2, e3, and back to e4, effectively passing a turn, and could also start from e4 to f4 (first the wazir move) then g5, g6, f7, e7, d6, d5, and back to e4. Example: The standard chess pawn can be described as mfWcfF (ignoring the initial double move). There is no standard order of the components and modifiers. In fact, Betza often plays with the order to create somehow pronounceable piece names and artistic word play. Betza does not use the small letter i. It is used
