Having been thinking a lot lately about the topic of 'No Capture Chess', I came up with an interesting idea that I would like to share with you. The idea concerns a new piece, which can well be called a fairy piece, despite the fact that its presence on the chessboard is not constant and is associated with very unusual functions that are not found in other fairy pieces.
Gravitatur
Gravitatur is a fairy chess piece that, when it appears on a square of the chessboard, attracts to itself all the pieces of both players that are in its direct action zone. Gravitatur is active in the following directions:
All pieces of both players standing on the squares of the chessboard in the zone of Gravitatur's activity (in its visibility zone) are attracted to it closely so that upon completion of the Attraction they must be next to it on the adjacent squares.
Gravitatur does not belong to any of the players, but is used in the game in turn, starting with the player with the white pieces. The Gravitatur's move consists of the player, in his turn to move, placing it on any free square of the chessboard. After the Gravitatur has attracted all possible pieces, it is removed from the board and the player who used the Gravitatur makes a normal move with any of his chess pieces.
For example,
The game begins and White decides to place Gravitatur on the d4 square:
Gravitatur attracts all pieces that are within its line of sight:
After which, Gravitatur is removed from the board, and now White must make a normal chess move with any of his pieces:
So, we have Gravitatur Chess
The game uses a standard chess set plus one more piece - the Gravitatur. The Gravitatur is not the property of the players and is used by them in turn.
In the initial setup, the black king is located on the d8 square.
The game follows the FIDE Rules of Chess except for the following:
Use of Gravitatur
Before making a move, the player places Gravitatur on any free square on the chessboard. Having attracted the pieces towards itself, Gravitatur is removed from the board and the player continues his turn, making a normal move with his chess piece. Restrictions Declaring a check always limits the use of Gravitatur and the player's subsequent move: — if a player is in check, he cannot use Gravitatur during this turn. — a player cannot place Gravitatur in such a way that after using it his king will be in check. — a player cannot make a move with a regular chess piece if, after using Gravitatur, the opponent's king is in check. In this case, such a player's move is considered complete.
Teleportation
During the game, instead of moving the King, a player can swap it with any other piece except the Pawn. This is called Teleportation - the King is placed on a square where a friendly piece is standing, which in turn is transferred to the square that is vacated by the King. Teleportation is impossible if the King is in check. The King cannot teleport to a square that is under attack by enemy pieces. Teleportation is not a substitute for castling in regular chess - it is an independent move that can be performed during the game as many times as the situation on the board requires.
Moving chess pieces
All chess pieces move according to the FIDE Rules of Chess with the following exceptions: There are no captures in the game except for kings. The king is the only piece in the game that can capture. Chess pieces, except for kings, are not aggressive towards each other, but can declare check and checkmate to the opponent's king.There is no castling and en passant capture in the game.
Goal of the game
As in Standard Chess, each player's goal is to place the opponent's king "under attack" so that the opponent has no legal move. A player who achieves this goal is said to have "checkmated" the opponent's king and won the game. All goals and objectives, as well as achieving a win or a draw, are fully consistent with the norms and laws of FIDE Chess.
To illustrate the above, let's look at one puzzle and try to find a solution:
White to move and mate in 1
Black's last move was to Teleport their king from e8 to a8, swapping places with the rook. However, this seemingly safe maneuver turns out to be fatal for them. White places Gravitatur on a4:
1. Ga4
After which they checkmate with the queen on a6. The full move notation is as follows: 1. Ga4/Qa6#
