Detailed Description

A board for Sit-tu-yin (Myanmar Traditional Chess, Burmese Chess)

Sittuyin is the traditional variant of chess in Myanmar. It is an old game (9th century) closely related to Makruk and Chaturanga. There has been a wide variety of local or temporary rules.

Each side begins with four Pawns on the left side on their third rank and four Pawns on the right side on their fourth rank.

In the initial phase of the game the red side places their pieces behind their Pawns. After that the black side places their pieces. Rooks must be placed on the back rank. After all pieces have been placed the red side makes their first move.

Sittuyin pieces move like Makruk (Thai Chess) pieces: The movements of King, Rook, Knight, and Pawn are the same as in Makruk, Shatranj, and chess. There are no "modern" moves: no pawn double steps, and no castling. The General moves one square diagonally. The Elephant has the same move- ment but can also make a step straight forward.

If a side has no General then a Pawn can be promoted to General. This can only be done by a side's last Pawn or within the opponent's half from a square that is part of a main diagonal. Promotion counts as a move of its own. When promoting the Pawn either remains on its current square or makes a General's move. The promotion move must not give check or capture an opponent piece. Pawn promotion is optional, not oligatory: The Pawn can also make a normal move or capture.

Checkmating the opponent King wins. Stalemate is a draw. A draw can be claimed if no pawns have been moved and no captures have been made for fifty consecutive moves. A game will be drawn if it is impossible for the remaining pieces to give mate. There is no 3-fold repetition rule.

Endgames with King and Rook, or King, Elephant and General, or King, Knight and General against a lone King must be won within a defined number of moves, else the game is drawn.

Note: Rules: The Official Rules by the Myanmar Chess Federation (as described by Maung Maung Lwin).; : Set-up phase with alternating red and black piece drops.

Member Function Documentation

void Chess::SittuyinBoard::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::ShatranjBoard.

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

virtual

Creates and returns a deep copy of this board.

Reimplemented from Chess::MakrukBoard.

int Chess::SittuyinBoard::countingLimit ( ) const

protectedvirtual

Returns maximum count of plies allowed to finish the game: Limit for Board's Honour or Pieces' Honour counting.

Reimplemented from Chess::MakrukBoard.

MakrukBoard::CountingRules Chess::SittuyinBoard::countingRules ( ) const

protectedvirtual

Returns type of counting rules to apply. Default: Makruk.

See also: OukBoard

Reimplemented from Chess::MakrukBoard.

QString Chess::SittuyinBoard::defaultFenString ( ) const

virtual

Returns the variant's default starting FEN string.

Reimplemented from Chess::MakrukBoard.

void Chess::SittuyinBoard::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::MakrukBoard.

void Chess::SittuyinBoard::generatePawnMoves	(	int	sourceSquare,
		QVarLengthArray< Move > &	moves
	)		const

protectedvirtual

Appends generated pseudo-legal pawn moves to moves

Reimplemented from Chess::MakrukBoard.

bool Chess::SittuyinBoard::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::WesternBoard.

bool Chess::SittuyinBoard::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.

See also: AntiBoard; HordeBoard

Reimplemented from Chess::WesternBoard.

int Chess::SittuyinBoard::promotionRank ( int file = 0 ) const

protectedvirtual

Returns the relative rank of pawn promotions counting from 0 for the first rank. The default returns 5 for promotions on the sixth rank. The formal file parameter is unused. Override this method if the promotion rank is not uniform.

See also: SittuyinBoard

Reimplemented from Chess::MakrukBoard.

QList< Piece > Chess::SittuyinBoard::reservePieceTypes ( ) const

protectedvirtual

Returns a list of piece types that can be in the reserve, ie. captured pieces that can be dropped on the board.

The default implementation returns an empty list.

Reimplemented from Chess::Board.

Result Chess::SittuyinBoard::result ( )

protectedvirtual

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

Reimplemented from Chess::MakrukBoard.

QString Chess::SittuyinBoard::variant ( ) const

virtual

Returns the name of the chess variant.

Reimplemented from Chess::MakrukBoard.

bool Chess::SittuyinBoard::variantHasDrops ( ) const

virtual

Returns true if the variant allows piece drops. The default value is false.

See also: CrazyhouseBoard

Reimplemented from Chess::Board.

bool Chess::SittuyinBoard::variantHasOptionalPromotions ( ) const

virtual

Returns true if the variant allows to skip a promotion (or a move treated as promotion) and make a normal move instead. The default value is false, i.e. mandatory promotions.

See also: GrandBoard; SeirawanBoard

Reimplemented from Chess::Board.

bool Chess::SittuyinBoard::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.

void Chess::SittuyinBoard::vMakeMove	(	const Move &	move,
		BoardTransition *	transition
	)

protectedvirtual

Makes move on the board.

This function is called by makeMove(), and should take care of everything except changing the side to move and updating the move history.

Details about piece movement, promotions, captures, drops, etc. should be stored in transition. If transition is 0 then it should be ignored.

Reimplemented from Chess::MakrukBoard.

bool Chess::SittuyinBoard::vSetFenString ( const QStringList & inputFen )

protectedvirtual

This method reads FEN with full Makruk/Ouk counting support (A), standard FEN (B), and short FEN-like notation without castling rights and en passant fields (C). The latter two use Western counting and ignore Makruk counting.

A: rnsmksnr/8/pppppppp/8/8/PPPPPPPP/8/RNSKMSNR w - 0 0 1

B: rnsmksnr/8/pppppppp/8/8/PPPPPPPP/8/RNSKMSNR w - - 0 1 C: rnsmksnr/8/pppppppp/8/8/PPPPPPPP/8/RNSKMSNR w 0 1

FEN with Ouk initial move rights instead of castling rights are supported by OukBoard. Format C does not carry this information. Also see OukBoard.

Reimplemented from Chess::MakrukBoard.

void Chess::SittuyinBoard::vUndoMove ( const Move & move )

protectedvirtual

Reverses move on the board.

This function is called by undoMove() after changing the side to move to the side that made it.

Note: Unlike vMakeMove(), this function doesn't require subclasses to update the zobrist position key.

Reimplemented from Chess::MakrukBoard.
