how to create .fen file manually - 2007/02/28 07:43I want to know how to create .fen file manually for the chess positions. Whether from there can i allow the chess software to analysis the position. I have gnu free software version 5.0.
In the FEN-notation the chess-diagram is coded line by line with slashes between the lines. The pieces and pawns are coded by their first letter and the White pieces in upper-case. The empty squares are coded by the number of empty squares. Some additional fields are added: active color, castling possibilities, en passant possibility, half-move clock and move number. These field are needed to determine all possibilities for the next moves.
The FEN for the starting position is: rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1
And the FEN after move 1. e4: rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq e3 0 1
