2 | Win by eliminating all opponent pieces of the same type.
5 Standard rules apply, but the game ends when all pieces of a kind disappeared.
6 Kings are treated as normal pieces (no royal power), but may castle -
7 without any concern about checks.
8 Pawns may promote into king.
9 If all pieces of a kind disappear, the game is lost; except if it's a
10 pawns extinction which results in a non-pawn extinction by capturing and
11 promoting on the last rank.
16 Win by eliminating all enemy pawns, or rooks, or knights, or bishops, or queen(s),
17 or king(s) (there may be several if promotions happened).
