Detailed Description

A board for Modern chess.

Modern chess is a variant of chess on a 9x9 board. Each side has an additional Pawn and a Minister piece with Bishop and Knight movements. At start the Kings have the Queens to their right (f1, d9) and the Ministers to their left.

The King moves two squares towards the rook when castling. Pawns may also promote to Minister.

This variant was introduced in 1964 (Madrid) by Gabriel Maura, Puerto Rico.

Note: Rules: https://en.wikipedia.org/wiki/Modern_Chess_(chess_variant) This board implements the rules of 1964 and does not support Bishop adjustment moves.

Constructor & Destructor Documentation

◆ ModernBoard()

Chess::ModernBoard::ModernBoard ( )

Creates a new ModernBoard object.

Member Function Documentation

◆ addPromotions()

void Chess::ModernBoard::addPromotions	(	int	sourceSquare,
		int	targetSquare,
		QVarLengthArray< Move > &	moves
	)		const

protectedvirtual

Adds pawn promotions to a move list.

This function is called when a pawn can promote by moving from sourceSquare to targetSquare. This function generates all the possible promotions and adds them to moves.

Reimplemented from Chess::WesternBoard.

◆ castlingFile()

int Chess::ModernBoard::castlingFile ( WesternBoard::CastlingSide castlingSide ) const

protectedvirtual

Defines the file a king may castle to on castlingSide. Defaults: 2 (c-file) and width() - 2 (normally g-file)

Reimplemented from Chess::WesternBoard.

◆ copy()

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

virtual

Creates and returns a deep copy of this board.

Implements Chess::Board.

◆ defaultFenString()

QString Chess::ModernBoard::defaultFenString ( ) const

virtual

Returns the variant's default starting FEN string.

Implements Chess::Board.

◆ height()

int Chess::ModernBoard::height ( ) const

virtual

Returns the height of the board in squares.

Reimplemented from Chess::WesternBoard.

◆ moveFromSanString()

Move Chess::ModernBoard::moveFromSanString ( const QString & str )

virtual

Converts a string in SAN format into a Move object.

Reimplemented from Chess::WesternBoard.

◆ sanMoveString()

QString Chess::ModernBoard::sanMoveString ( const Move & move )

virtual

Converts a Move object into a string in Standard Algebraic Notation (SAN).

Note: Specs: http://en.wikipedia.org/wiki/Algebraic_chess_notation

Reimplemented from Chess::WesternBoard.

◆ variant()

QString Chess::ModernBoard::variant ( ) const

virtual

Returns the name of the chess variant.

Implements Chess::Board.

◆ width()

int Chess::ModernBoard::width ( ) const

virtual

Returns the width of the board in squares.

Reimplemented from Chess::WesternBoard.
