Chess variant where:
- capturing is compulsory whenever possible (one can choose if there are more capturing moves);
- the player who loses all pieces wins;
- there is no check or checkmate: the king is a normal, capturable piece (its picture is different to emphasize this rule).
Otherwise the rules of chess apply, with the following differences:
- Stalemate is a win for the stalemated player (who is unable to move).
- There is no castling.
- Pawns can also promote to king.
