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. English-speaking players use the letters "K" for king, "Q" for queen, "R" for rook, "B" for bishop, and "N" for knight (since K is already used). "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 that must land immediately after first piece it encounters, instead of on or before it), pao (rider that can only land behind the first piece it encounters, instead of on or before it), o cylindrical (moving off one side of the board wraps to the other), z crooked (moving in a zigzag line like the boyscout), q circular movement (like the rose), and then (for pieces that start moving in one direction and then continue in another, like the gryphon). In addition, Betza has also suggested adding brackets to his notation: q<nowiki>[</nowiki>WF<nowiki>]</nowiki>q<nowiki>[</nowiki>FW<nowiki>]</nowiki> would be a circular king, which can move
