User:Simures/Mirodoly chess 12×12



The Mirodoly chess 12 by 12 is a variant of chess on a 144-cell board, which is the closest to classical chess. For the first time this variant of chess was described in 2017. Unlike classical chess, two new figures are introduced into the game: an Archer and a Sagittarius.

Start position
At the beginning of the game, the archers stand on the flanks, and the archers stand next to the king and queen, as shown in the diagram.



Archer
The archer's move is shown in the diagram. This is the third square from the archer, except for the moves of the rook and bishop. That is, these are only those cells of the third square from him, to which he can go with an enlarged letter L. When moves are alphanumeric recorded, the archer is denoted – A.



Sagittarius
Sagittarius move. These are cells of the opposite color of the fourth perimeter from Sagittarius. That is, if Sagittarius stands on a black square, then he attacks all the white cells of the fourth perimeter from him. If Sagittarius is standing on a white square, then he attacks, respectively, all the black cells of the fourth perimeter from him. When moves are alphanumeric recorded, Sagittarius is denoted by – S.

Principle of non-repeat
In the way both these new pieces move, the main principle of constructing the moves of all paired pieces of classical chess is retained in these chess. The essence of the principle is that no paired piece, either partially or as a whole, does not repeat the move of any other paired piece without a single cell.



Knight's move
In this chess there is a significant change in the course of the knight. The knight becomes a double. The horse becomes a two-jump piece. That is, a 144-cell horse walks up to two jumps in one straight direction.



Principle of straightness of the Knight's move
Therefore, if any figure is encountered on the straight path of the knight, the knight cannot jump over this figure.

A pawn, as in classical chess, up to the middle line can go straight forward freely, for any number of squares. And, accordingly, the rule of taking a pawn on the pass is preserved.

При рокировке разрешается сдвигать короля на ЛЮБОЕ ненулевое количество клеток вправо или влево. При буквенно-цифровой записи рокировка обозначается: К–0–0–0 (король рокировкой передвинулся вправо на три клетки), или 0–0–К (король рокировкой передвинулся в сторону ферзевого фланга на две клетки).

Approximate cost of figures:


 * Knight – 5 pawns
 * Rook – 6 pawns
 * Archer – 6 pawns
 * Sagittarius – 6 pawns
 * Bishop – 4 pawns
 * Queen – 12 pawns
