There are four required EPD fields, presented in this order:

1. a forsythe position description
2. color to move: 'w' or 'b'
3. castling rights: KQkq for white and black, king and queenside, '-' if none
4. if an en-passant move is possible, the file of the pawn which was just
advanced:  'a' through 'h', or '-' if no en-passant available.

Then there is FEN, which adds more attributes afterwards (var=value; etc;).

ObTest:
[D]r1bqkb1r/ppppn1pp/2n2P/3N/3P1p/5N/PPP1Q1PP/R1B1KB1R w KQkq - ; bm Ng5

ObSmiley:
