What is a FEN?

FEN (Forsyth–Edwards Notation) is a one-line text description of a chess position. It has six fields: piece placement (rank 8 to rank 1, / between ranks, digits for empty squares), side to move (w/b), castling rights, en passant target square, the halfmove clock (for the 50-move rule), and the fullmove number.
