Pieces in hand are written between [] after the board in FEN. We are still discussing how to best indicate virginity of pieces. This info seems to make the castling field superfluous, and could perhaps replace it. Reinhard proposed two hex numbers separated by a period, representing a bitmap of the virgin pieces, like

rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR [HEhe] w FF.FF - 0 1

My current implementation regarding virgin pieces is that, R in a1, h1, a8 and h8 I considered as virgins. Basically bishops and other pieces that are still on their original squares are considered virgins.Of course virginity loses when that piece has been found to move from that square in the move history. Rooks on b/c/d/e/f/g files can never be virgins, same with other pieces like bishops on a/b/d/e/g/h files can not be virgins. In one of those games I have seen Fairy Max as black castles e8f8, then couple of moves later it gates by moving f8d8e Sad.
