Detailed Description

A board for Courier Chess.

Courier Chess is a 12x8 board variant that has been popular in medieval Europe, especially in the countries of the Holy Roman Empire (esp. Germany, Netherlands) from the 12th to the 18th century alongside Shatranj and then Chess (influencing the transformation from the former to the latter).

The Queen and the Bishop in Courier Chess have the old Shatranj movements of the Ferz (Counselor, one square diagonally) and the Alfil (War Elephant, leaps two squares diagonally). King, Rook, and Knight have normal moves. There are additional pieces: Every side has one Mann who moves like a King, and one Schleich with Wazir movement (one square forward, backward, left or right). Every side has two Currier or Courier pieces with modern Bishop movement. Courier Chess has no Pawn double step option and no castling. A Pawn can only promote to Queen.

The effective starting position has the white Queen and Rook Pawns on ranks 4 (introducing ceremonial double steps from rank 2) and the Queen moves to g4 from g2. The black pieces do mirrorwise.

A side wins if their opponent cannot make a legal move (mate or stalemate), or has no pieces left besides their "bare" King. However, a bare King is given one chance to get level by the next move: Two bare kings is a draw.

Member Enumeration Documentation

◆ CourierPieceType

enum Chess::CourierBoard::CourierPieceType

protected

Special piece types for Courier variants.

Enumerator

Courier

Currier, Courier (diagonal slider) is modern Bishop.

Mann moves like King

Mann

Schleich moves like Wazir (1 square orthog.).

Constructor & Destructor Documentation

◆ CourierBoard()

Chess::CourierBoard::CourierBoard ( )

Creates a new CourierBoard object.

Member Function Documentation

◆ copy()

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

virtual

Creates and returns a deep copy of this board.

Reimplemented from Chess::ShatranjBoard.

◆ defaultFenString()

QString Chess::CourierBoard::defaultFenString ( ) const

virtual

Returns the variant's default starting FEN string.

Reimplemented from Chess::ShatranjBoard.

◆ generateMovesForPiece()

void Chess::CourierBoard::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::ShatranjBoard.

◆ inCheck()

bool Chess::CourierBoard::inCheck	(	Side	side,
		int	square = 0 ) const

protectedvirtual

Returns true if side is under attack at square. If square is 0, then the king square is used.

Reimplemented from Chess::ShatranjBoard.

◆ variant()

QString Chess::CourierBoard::variant ( ) const

virtual

Returns the name of the chess variant.

Reimplemented from Chess::ShatranjBoard.

◆ vInitialize()

void Chess::CourierBoard::vInitialize ( )

protectedvirtual

Initializes the variant.

This function is called by initialize(). Subclasses shouldn't generally call it by themselves.

Reimplemented from Chess::ShatranjBoard.

◆ width()

int Chess::CourierBoard::width ( ) const

virtual

Returns the width of the board in squares.

Reimplemented from Chess::WesternBoard.

Member Data Documentation

◆ WazirMovement

const unsigned Chess::CourierBoard::WazirMovement = 64

staticprotected

Movement mask for Wazir moves. (Schleich)
