Description

ChessBoard is a Python implementation of the FIDE laws of chess. The main goal is to implement all applicable rules in a simple, straightforward way. The intention is not to be fast but to be easy to understand and to be complete. Many other implementation has known problems with castling, stalemate or other more or less special rules.

Features:

The moves of the pieces
Castling
En passant
Check detection
Checkmate detection
Stalemate detection
Draw by the fifty moves rule detection
Draw by the three repetitions rule detection
Get valid locations support
Imoprt and export of Forsyth-Edwards Notation strings.
Add text moves in the AN, SAN and LAN standards.
Export moves in the AN, SAN and LAN standards.
Undo and Redo.
Goto a specified move.

Unpack the source and start example with "python ChessClient.py"

Keys:

Left - Undo last move.
Right - Redo move.
F - Print current board as FEN.
A - Print all moves as Algebraic Notation.
S - Print all moves as Standard Algebraic Notation.
L - Print all moves as Long Algebraic Notation.

Changes

Fixed a bug in resetBoard() and setFEN(). The game_result variable wasn't reset.
Fixed a bug in addTextMove() that caused a crash sometimes when invalid data was entered.
Added a new reson, AMBIGUOUS_MOVE, for text moves that could be perfomed by two different pieces.

I know :-) The ChessClient.py application is just a proof-of-concept and when the ChessBoard.py implementation returns "MUST_SET_PROMOTION" it will always set the promotion value to Queen.

Nice. Pawn promotion doesn't give you the option of selecting knight, bishop or rook though.

Hehe..that's because I have one very thorough and active user/tester, Jasper. Without you I would probably never have got around to make another release of ChessBoard.

Reminds me of chess on television from the 1980s - that's a good thing, by the way. A clean and usable implementation of the game!
