2 | You have a king and an antiking. King cannot be let in check, but antiking | |
3 | must always stay under check. Antiking captures his own kind. | |

6 | A new piece is introduced: the antiking, noted by the letter 'A' in diagrams | |
7 | and PGNs. This piece must always remain under (orthodox) check: it is | |
8 | considered in (anti-)check when not attacked by any enemy piece. In such a | |
9 | situation, the antiking must move immediately to an attacked square. | |

12 | The antiking is a royal figure, and thus cannot be captured. |
13 | It captures only the pieces of his color (to help checkmating the opponent's | |
14 | antiking, but this also complicates standard checkmate). | |

23 | Although antiking captures his color, it doesn't check his king - it | |
24 | doesn't check the opponent's king either. | |
25 | li. | |
26 | Since it would allow a basic tactic (keep antiking touching opponent's | |
27 | king), kings do not attack antikings. | |

36 | ...Or do both at the same time, as on the following diagram after 3.Qxf7# |
37 | (the black antiking was on g3). | |
