Detailed Description

A board for Horde Chess and Dunsany's Chess (Defaults are set to lichess.org (SF) variant)

Horde chess is a variant of standard chess with different setup. It is similar to a variant introduced by Lord Dunsany in 1942.

The black side plays with a standard set of pieces. However white has 36 pawns and no other pieces.

White has to mate the black king, black has to capture all pawns of the white horde in order to win. Standard chess rules apply. White pawns on the first and second ranks can make a double step.

Note
Rules: https://en.wikipedia.org/wiki/Dunsany%27s_chess#Horde_Chess

HordeBoard uses Polyglot-compatible zobrist position keys, so Horde Chess opening books in Polyglot format can be used.

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

Creates and returns a deep copy of this board.

Reimplemented from Chess::StandardBoard.

Reimplemented from Chess::StandardBoard.

bool Chess::HordeBoard::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.

HordeBoard

Reimplemented from Chess::WesternBoard.

Result Chess::HordeBoard::result ( )
virtual

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

Reimplemented from Chess::WesternBoard.

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

Returns the name of the chess variant.

Reimplemented from Chess::StandardBoard.

bool Chess::HordeBoard::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::WesternBoard.
