Detailed Description

A board for Grand Chess.

Grand Chess is a variant of standard chess on a 10 x 10 board with Capablanca chess pieces. This game was introduced in 1984 by Christian Freeling, The Netherlands.

Each side has one Cardinal (Archbishop, Bishop+Knight) and one Marshal (Chancellor, Rook+Knight) in addition to the standard pieces. GrandBoard uses the Capablanca names Archbishop and Chancellor.

Initially each side has ten pawns on their third ranks. Most of the other pieces start on their second ranks. The rooks are placed at the corners. Castling is not allowed in Grand Chess.

Pawns can make an initial double step and can be captured en passant. When reaching their eigth or ninth ranks pawns can optionally be promoted. Pawns can only promote to an own captured piece. On the tenth rank a pawn must be promoted. If promotion is impossible, then the pawn cannot advance to the tenth rank. It can give check to a king on the end rank nevertheless.

Constructor & Destructor Documentation

◆ GrandBoard()

Chess::GrandBoard::GrandBoard ( )

Creates a new GrandBoard object.

Member Function Documentation

◆ copy()

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

virtual

Creates and returns a deep copy of this board.

Reimplemented from Chess::CapablancaBoard.

◆ defaultFenString()

QString Chess::GrandBoard::defaultFenString ( ) const

virtual

Returns the variant's default starting FEN string.

Reimplemented from Chess::CapablancaBoard.

◆ generateMovesForPiece()

void Chess::GrandBoard::generateMovesForPiece	(	QVarLengthArray< Move > &	moves,
		int	pieceType,
		int	square
	)		const

virtual

Generates pseudo-legal moves for a piece of pieceType at square square.

Note: It doesn't matter if square doesn't contain a piece of pieceType, the move generator ignores it.

Reimplemented from Chess::WesternBoard.

◆ hasCastling()

bool Chess::GrandBoard::hasCastling ( ) const

virtual

Returns true if castling is allowed. The default value is true.

See also: ShatranjBoard

Reimplemented from Chess::WesternBoard.

◆ height()

int Chess::GrandBoard::height ( ) const

virtual

Returns the height of the board in squares.

Reimplemented from Chess::WesternBoard.

◆ variant()

QString Chess::GrandBoard::variant ( ) const

virtual

Returns the name of the chess variant.

Reimplemented from Chess::CapablancaBoard.

◆ vIsLegalMove()

bool Chess::GrandBoard::vIsLegalMove ( const Move & move )

virtual

Returns true if move is a legal move.

This function is called by isLegalMove() after making sure that there is a pseudo-legal move same as move. This function shouldn't check for the existence of move by generating moves.

The default implementation only checks if the position after move is legal.
