pieces | 'Neutral piece' | фигуры |
Neutral piece: | Belongs to whichever side chooses to use it. It can therefore be moved or captured by White or Black, and in Circe it is reborn according to capture. A King may not be moved onto a square controlled by a neutral piece, because of self-check. | Нейтральная фигура. Принадлежит той стороне, которая его использует. Таким образом, может ходить за любую сторону или быть взятой любой из сторон. В Circe поле возврата определяется взятием. Король не может ходить на поле, контролируемое нейтральной фигурой, т.к. это является самошахом. |
conditions | 'Alphabetic Chess', 'PWC', 'Einstein Chess', 'Republican Chess (Type 2)' | условия |
Alphabetic Chess: | The squares are considered in the order a1, a2…a8, b1…b8, c1 and so on to h8. At each turn, only the unit standing on the square which comes earliest in this order may move. However check and mate are normal. | Очередность полей определяется как a1, a2…a8, b1…b8, c1 итд. до h8. Каждый раз может ходить только фигура, стоящая на поле, которое в данной очередности стоит раньше других. Однако шах и мат происходят по обычным правилам. |
Einstein chess: | All units (Ks excluded) change their type when they move, according to a precise pattern. For non-capture moves: Q>R, R>B, B>S, S>P, P remains P. For capture-moves: R>Q, B>R, S>B, P>S, Qremains Q. | [ENG] All units (Ks excluded) change their type when they move, according to a precise pattern. For non-capture moves: Q>R, R>B, B>S, S>P, P remains P. For capture-moves: R>Q, B>R, S>B, P>S, Qremains Q. |
PWC: | When a capture is made, the captured unit (except a King) is replaced on the square the capturing unit just leaves. A Pawn is immovable on its 1st rank. | При взятии взятая фигура (исключая короля) перемещается на поле, которое только что покинула берущая фигура. Пешка неподвижна на своей 1-ой линии. |
Republican Chess (Type 2): | There are no Kings : if the side which has played can put the opposite King on a square where it would be legally mate, then the opposite King is put on such a square. The opposite side can then put itself the other King on a square where it is mated. | [ENG] There are no Kings : if the side which has played can put the opposite King on a square where it would be legally mate, then the opposite King is put on such a square. The opposite side can then put itself the other King on a square where it is mated. |
