   6   In order to not rethink a big part of the code, the white move has to be
   7   played before the black one. However, the black player doesn't see it.

   9 p So both players play "at the same time". Resolving rules:
  10 ul
  11   li.
  12     If both moves arrive on the same square, both pieces disappear except
  13     if one is a king. In this case only the king remains.
  14   li.
  15     If a capture was intended but the target moved, the move is still played
  16     but doesn't capture anything.
  17 p.
  18   Such captures can be anticipated by capturing our own pieces.
  19   If the enemy captures as predicted, his piece disappears.
  20   If he doesn't, the self-capture isn't undone.

  30   Due to the simultaneity, it is possible that a king is captured for example
  31   after escaping a check in a wrong way, as the following diagram shows.
  32   So, capturing the king counts as a win, of highest priority.
  33   A checkmate wins too, but if your king is captured and the other still on
  34   the board (even if it is mated), you lose.
