I was going through a game on Wikipedia, and I will stop here for now. This goes up to move 11, followed by a checkmate variation that my code is currently recognizing only as check.
Here's a curious comment George Jelliss made in this game: "To give a direct check to the king the checking piece must come from the other board, so it is necessary first to transfer forces to the other board." On one interpretation, this is not true at all. Pieces can't capture by moving to an empty space and transferring to an occupied square on the other board. So I assume they can't check that way either. In the earlier examples of checkmate given on Wikipedia, the check comes from a piece on the same board as the King. Maybe what he means is that a piece must move from the other board to be on a space from which it can check the King.
