Wild 9: Here there are two kings. If you sweep the board in the following order: a1 a2 a3...a8 b1 b2..h8, the king you come to first is the one you must mate. The other king is just an ordinary piece.
Warning: xboard may refuse to make certain moves, because they're not legal according to its definition of legal (like leaving one of your kings in check). THESE MOVES MUST BE TYPED IN!
