Body: <p>How are null moves indicated in PGN which Lucas Chess will correctly interpret?</p>
  <p>Context: I want to make PGN files of solution lines of series problems, in order to replay them in Lucas Chess. In serieshelpmates, Black plays a series of moves, with no White moves in between, until White checkmates. In other series problems, White plays a series of moves, with no Black moves in between.</p>
  <p>Lucas Chess doesn't accept <code>null</code> or <code>--</code> as valid PGN. (<a href="https://chess.stackexchange.com/a/21413">This answer</a> mentioned <code>--</code>.)</p>
  <p>I use Lucas Chess because it enables the user to make the app display the board diagram nice and big, with figurines in a font that is nice and clear, and even specify the square colours so that they are nice and unobtrusive. I could try another chess app instead, but I need graphics that are suitable for people whose vision is not 20/20.</p>

  Lucas Chess doesn't accept `null` or `--` as valid PGN. ([This answer](https://chess.stackexchange.com/a/21413) mentioned `--`.)
