Some wise words? anyone?
thanks in advance
FEN is simple once you know it.
r1bqk2r/pppp1ppp/2n2n2/1Bb1p3/4P3/2N2N2/PPPP1PPP/R1BQ1RK1 b kq - 0 5
Black is lower case letters
White is Capital Letters
You will have 8 sets of letters and numbers.
Letters are pieces
Numbers are BLANK squares on any given row. Rows run down the board, there are 8 rows on a board.
In my example the back row for black reads like this...
rook, Empty Square, bishop, queen, king, 2 Empty Squares, rook.
White's back row (the last of 8 rows) reads as follows
Rook, Empty Square, Bishop, Queen, Empty Square, Rook, King, Empty Square
The slashes (/) separate the 8 rows on a board.
Here is what you see after the 8 rows...
b kq - 0 5
b=black to move
kq means that black can castle king side, or queen side in this game.
If white could still castle, you would see this...
White already castled, so you don't see that!
Not sure what 0 is...
5 means Move 5 I believe.
Go to your board, copy out the fen and compare it to your position. You'll figure it out very fast, it's rather simple... and you will be able to write fen on your own once you understand it.
You know you've got it right once you realize that every row adds up to 8 pieces and empty squares.
r1bqk2r = 8 squares
R1BQ1RK1 = 8 squares
The 4th row has a loan white Pawn
