Algebraic notation (chess) board. Thus each square has a unique identification of file letter followed by rank number. (For example, White's king starts the game on square e1; Black's knight on b8 can move to open squares a6 or c6.) Each piece type (other than pawns) is identified by an uppercase letter.

"S" (from the German "Springer") was also used for the knight in the early days of algebraic notation and is still used in some chess
Fairy chess piece is a piece that moves by jumping over another piece (called a hurdle). The hurdle can be any piece of any color. Unless it can jump over a piece, a hopper cannot move. Note that hoppers generally capture by taking the piece on the destination square, "not" by taking the hurdle (as is the case in checkers). The exceptions are locusts which are pieces that capture by hopping over its victim. They are sometimes considered a type of hopper. There are no hoppers in Western chess. In xiangqi, the cannon captures as a hopper (when not capturing, it is a
