Detailed Description

A board for ASEAN-Chess.

ASEAN-Chess is a standardised variant of chess defined by the ASEAN Chess Confederation. It is based both on standard chess and Makruk.

ASEAN-Chess is played on a standard chess board. The pieces are named as in standard chess, but have the movements of Makruk. So the Queen has the movement of the Met (Ferz, 1 square diagonally), and the Bishop moves like the Khon in Makruk (or the Silver General in Shogi): 1 square diagonally or 1 square straight forward. There is no castling and pawns have no initial double steps.

The starting position has the pawns on the third own rank, like in Makruk. However, the pieces on the base rank are placed in the starting order of standard chess. Pawns promote on the eighth rank to either Queen, Rook, Bishop, or Knight.

Like in standard chess giving mate wins, stalemate is a draw, insufficient material is a draw, and after fifty consecutive moves without any pawn move and any capture a draw can be claimed. However, three-fold repetition of a move does not achieve a draw. A game is drawn when no side can be checkmated at all by any sequence of legal moves.

When a King is left without any pieces the material on the board is evalua- ted at once. The stronger side must give mate within 16 moves if they have a Rook. If they have a Bishop and a Queen the limit is 44 moves. If they have a Knight and a Queen the limit is 64 moves.

Member Function Documentation

void Chess::AseanBoard::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::AseanBoard::copy ( ) const

virtual

Creates and returns a deep copy of this board.

Reimplemented from Chess::MakrukBoard.

int Chess::AseanBoard::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::AseanBoard::countingRules ( ) const

protectedvirtual

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

See also: OukBoard

Reimplemented from Chess::MakrukBoard.

QString Chess::AseanBoard::defaultFenString ( ) const

virtual

Returns the variant's default starting FEN string.

Reimplemented from Chess::MakrukBoard.

int Chess::AseanBoard::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.

Reimplemented from Chess::MakrukBoard.

Result Chess::AseanBoard::result ( )

protectedvirtual

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

Reimplemented from Chess::MakrukBoard.

QString Chess::AseanBoard::variant ( ) const

virtual

Returns the name of the chess variant.

Reimplemented from Chess::MakrukBoard.

QString Chess::AseanBoard::vFenString ( Board::FenNotation notation ) const

protectedvirtual

When using Makruk counting rules (no Western counting)

This method sets the castling rights field to "-" for Makruk.
The ep field is replaced by the counting limit (in plies).
Makruk ply counting replaces the reversible move count.
This method uses an own total ply counter to keep track of the full move count.

Examples: Default FEN: rnsmksnr/8/pppppppp/8/8/PPPPPPPP/8/RNSKMSNR w - 0 0 1 KSSMvK black mates: 8/8/2m5/s7/8/1k6/1s6/1K6 w - 44 38 182

Reimplemented from Chess::MakrukBoard.

bool Chess::AseanBoard::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.
