| 30 | p There are two ways to win: |

| 32 | li Checkmate opponent king |
| 33 | li Anti-checkmate opponent antiking |
| 34 | p ...Or maybe do both at the same time? |
| 35 | |
| 36 | p Note 1: athough antiking captures his color, it doesn't check his king. |
| 37 | |
| 38 | p |
| 39 | | Note 2: since it would allow a basic tactic (keep antiking touching opponent's |
| 40 | | king), kings do not attack antikings. |
| 41 | |
| 42 | p Note 3: an antiking does not check opponent's antiking. |
