A hint to you, Leonid: if you like to see a diagram for the notation above: (1) Stick a [D] directly before the FEN string, (2) append (blank seperated) colour to move, i.e. b or w (3) append (blank seperated) castling rights: - for nothing, KQkq or part of it for white/black king side/queen side (4) append (blank seperated) e.p. info: - for "no e.p. possible" You can look up the details in the FEN standard, part of the PGN standard. Look at the line below, which I typed in, and see the diagram, provided not by me, but by the CCC web server, which recognizes the [D] and FEN after it, and inserts the graphics. You can do that also. [D]knq3q1/rq1q1qbQ/Qq2Q3/1Qn1Q2B/Q1qN1Q1r/4K1B1/1q4QR/1N1q3Q w - - Chest says "no mate in 9" (216 seconds, K7/600 335MB hash). I will ask for more depth...
