Detailed Description

A board for EuroShogi.

EuroShogi is a variant of Shogi which is played on a 8x8 board. In this variant either side begins with King, two (Gold) Generals, two Bishops (on squares of different colours), two Knights, one Rook (on 2nd rank), and eight Pawns on the third rank. Shogi rules apply.

A Knight leaps like a chess Knight, but only in the two forward directions. In contrast to Shogi, a Knight can also move one square sideways. Therefore Knights can be dropped on any empty square of the board.

The promotion zone consists of the three furthest ranks. In case of a position occurring for the third time with the same player to move and the same pieces in hands, the game is drawn. However, if this situation arises from a series of checks, the side giving perpetual check loses the game.

EuroShogi was introduced in 2000 by Vladimír Pribylinec.

Constructor & Destructor Documentation

◆ EuroShogiBoard()

Chess::EuroShogiBoard::EuroShogiBoard ( )

Creates a new EuroShogiBoard object.

Member Function Documentation

◆ copy()

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

virtual

Creates and returns a deep copy of this board.

Reimplemented from Chess::ShogiBoard.

◆ defaultFenString()

QString Chess::EuroShogiBoard::defaultFenString ( ) const

virtual

Returns the variant's default starting FEN string.

Reimplemented from Chess::ShogiBoard.

◆ generateMovesForPiece()

void Chess::EuroShogiBoard::generateMovesForPiece	(	QVarLengthArray< Chess::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::ShogiBoard.

◆ height()

int Chess::EuroShogiBoard::height ( ) const

virtual

Returns the height of the board in squares.

Reimplemented from Chess::ShogiBoard.

◆ promotionRank()

int Chess::EuroShogiBoard::promotionRank ( ) const

protectedvirtual

Returns the lowest (relative) rank of the promotion zone.

Reimplemented from Chess::ShogiBoard.

◆ ranksAreAllowed()

bool Chess::EuroShogiBoard::ranksAreAllowed ( ) const

protectedvirtual

Returns whether the current position has no pieces on forbidden ranks.

Reimplemented from Chess::ShogiBoard.

◆ result()

Result Chess::EuroShogiBoard::result ( )

virtual

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

Reimplemented from Chess::ShogiBoard.

◆ variant()

QString Chess::EuroShogiBoard::variant ( ) const

virtual

Returns the name of the chess variant.

Reimplemented from Chess::ShogiBoard.

◆ vInitialize()

void Chess::EuroShogiBoard::vInitialize ( )

protectedvirtual

Initializes the variant.

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

Reimplemented from Chess::ShogiBoard.

◆ width()

int Chess::EuroShogiBoard::width ( ) const

virtual

Returns the width of the board in squares.

Reimplemented from Chess::ShogiBoard.
