Detailed Description

A board for Change-Over Chess.

Change-Over Chess was introduced by L. Russel Chauvenet, USA, in 1943.

Moved pieces (except for Kings) change their type at the end of the move in a circular path in opposite way to Circular Gryphon Chess. A Pawn becomes a Queen, a Queen transforms to a Rook, Rook changes to Bishop, Bishop to Knight, Knight to Pawn.

This variant uses a standard setup and giving mate to the King wins. The number of Queens, Rooks, Bishops and Knights are not restricted in contrast to Circular Gryphon Chess.

Constructor & Destructor Documentation

◆ ChangeOverBoard()

Chess::ChangeOverBoard::ChangeOverBoard ( )

Creates a new ChangeOverBoard object.

Member Function Documentation

◆ copy()

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

virtual

Creates and returns a deep copy of this board.

Reimplemented from Chess::CircularGryphonBoard.

◆ defaultFenString()

QString Chess::ChangeOverBoard::defaultFenString ( ) const

virtual

Returns the variant's default starting FEN string.

Reimplemented from Chess::CircularGryphonBoard.

◆ generateMovesForPiece()

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

protectedvirtual

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::GryphonBoard.

◆ isLegalPosition()

bool Chess::ChangeOverBoard::isLegalPosition ( )

protectedvirtual

Returns true if the current position is a legal position. If the position isn't legal it usually means that the last move was illegal.

Reimplemented from Chess::GryphonBoard.

◆ successorType()

int Chess::ChangeOverBoard::successorType	(	int	type,
		bool	reversed = false ) const

protectedvirtual

Returns new piece type after moving a piece of type. For an undo move reversed must be set to true, the default value is false.

Reimplemented from Chess::CircularGryphonBoard.

◆ variant()

QString Chess::ChangeOverBoard::variant ( ) const

virtual

Returns the name of the chess variant.

Reimplemented from Chess::CircularGryphonBoard.
