Detailed Description

A board for the Game of Codrus, a Losing Chess variant.

The Game of Codrus is a predecessor of Losing Chess.

The King has no royal powers, so there is no check and the King can be captured. Castling is allowed. If a side can capture then they must make a capture move.

The side whose King is captured wins.

The Game of Codrus has been described in J. Brede's Alamanach, Denmark 1844. It is named after the Athenian King Codrus who sacrificed himself to save his people (1068 BC).

Constructor & Destructor Documentation

Chess::CodrusBoard::CodrusBoard ( )

Creates a new CodrusBoard object.

Member Function Documentation

void Chess::CodrusBoard::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::AntiBoard.

Board * Chess::CodrusBoard::copy ( ) const
virtual

Creates and returns a deep copy of this board.

Reimplemented from Chess::GiveawayBoard.

bool Chess::CodrusBoard::kingsCountAssertion ( int  whiteKings,
int  blackKings 
) const
protectedvirtual

Returns true if both counts of kings given by whiteKings and blackKings are correct. WesternBoard expects exactly one king per side.

AntiBoard
HordeBoard

Reimplemented from Chess::AntiBoard.

Result Chess::CodrusBoard::result ( )
virtual

Returns the result of the game, or Result::NoResult if the game is in progress.

Reimplemented from Chess::AntiBoard.

QString Chess::CodrusBoard::variant ( ) const
virtual

Returns the name of the chess variant.

Reimplemented from Chess::GiveawayBoard.

bool Chess::CodrusBoard::vIsLegalMove ( const Move &  move)
protectedvirtual

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.

Reimplemented from Chess::AntiBoard.

Result Chess::CodrusBoard::vResultOfStalemate ( ) const
protectedvirtual

Rules outcome of stalemate

Reimplemented from Chess::AntiBoard.
