In chess games, the **FEN notation** uses a single line to describe the contents of each box of the box in rows from top to bottom (seen from the white side). The characters describing the parts ar:

K | White King | k | Black King |

Q | White Queen | q | Black Queen |

R | White Rook | r | Black Rook |

B | White Bishop | b | Black Bishop |

N | White Knight | n | Black Knight |

P | White Pawn | p | Black Pawn |

1-8 | 1 to 8 empty boxes |

__Example:__ The starting position of a chess board is: `rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR`

The chessboard description is completed with 5 informations:

w or b | Indicates the next player (w = white, b = black) |

KQkq | Indicates possible castling. K and / or Q for black castle respectively coded King or Queen and likewise k and / or q for the white castle |

- or coordinate | Coordinates of a possible case of taking en passant |

0 to 50 | Number of moves since last catch |

1 to 999 | Move number |

FEN is the acronym for Forsyth-Edwards Notation, named after David Forsyth, a Scottish journalist who invented this notation and Steven Edwards who adapted it to make it unambiguous and compatible with computers.
