A small correction. Since castling is added as a '50-move resetter' in
compositions, the correct solution should probably be 'White indicates
that his next move will be castling, and claims a draw on grounds of the
50-move rule'. The actual castling will reset the counter, so after
1.OO, white can't claim a draw.
