Detailed Description

A board for Displaced-grid Chess.

Displaced-grid Chess is a variant of Grid Chess. The grid is shifted by one rank and one file. There are 25 regions of nine central 2x2, twelve 1x2 (or 2x1) and four 1x1 cells at the corners.

Introduced by Doug Grant in 1974, the variant is also known as DGChess.

Constructor & Destructor Documentation

◆ DisplacedGridBoard()

Chess::DisplacedGridBoard::DisplacedGridBoard ( )

Creates a new DisplacedGridBoard object.

Member Function Documentation

◆ copy()

Board * Chess::DisplacedGridBoard::copy ( ) const

virtual

Creates and returns a deep copy of this board.

Reimplemented from Chess::GridBoard.

◆ defaultFenString()

QString Chess::DisplacedGridBoard::defaultFenString ( ) const

virtual

Returns the variant's default starting FEN string.

Reimplemented from Chess::GridBoard.

◆ restriction()

bool Chess::DisplacedGridBoard::restriction	(	const Move &	move,
		bool	reverse = `false`
	)		const

protectedvirtual

Returns true if move fulfills the additional game rules. Set reverse to true if this is a move of the opponent side (not the side to move). Default value is false.

Reimplemented from Chess::GridBoard.

◆ variant()

QString Chess::DisplacedGridBoard::variant ( ) const

virtual

Returns the name of the chess variant.

Reimplemented from Chess::GridBoard.
