Help anyone? >Terry That notation is known as FEN. The position translates to: - - - - r r k - p p p - - p p - - - q p - - - p - - n - - - - - - - P - P Q - B - - - P - - - - P - P - P - P P R - - - - R K - To understand FEN, think of the first square as h8, and every row is ended by a /. So if you see a line like 4rrk1/ then you would skip four squares, make a rook, another rook, and then a king and then one blank square. The line then looks like this: - - - - r r k - the whole line: 4rrk1/ppp2pp1/2qp3p/2n5/2P1PQ1B/3P4/P1P1P1PP/R4RK1 w - - translates to the position at the top. Capital letters are White, small letters black. The 'w' says that white is to move. the next - is castling rights, and finally the last - is an en passant square if any. In this position, no one can castle and no en passant square is available, so both are '-'. Hope this helps! James
