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'. | |
7 | 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. | |
10 | ||
11 | p. | |
12 | The antiking is a royal figure, and thus cannot be captured. | |
13 | It captures only the pieces of his color. | |
14 | Antikings don't give check, and kings do not attack antikings. | |
