  29 p There are two ways to win:
  30 ol
  31     li Checkmate opponent king
  32     li Anti-checkmate opponent antiking
  33 p ...Or maybe do both at the same time?
  34
  35 p Note 1: athough antiking captures his color, it doesn't check his king.
  36
  37 p Note 2: since it would allow a basic tactic (keep antiking touching opponent's king), kings do not attack antikings.
  38
  39 p Note 3: an antiking does not check opponent's antiking.
