Chess Misc

position_eval.py

This is a command line tool for quickly evaluating a position in chess. Here are the basics you need to know to get started :

  • Input : Any FEN string(s) or a file containing FENs
>> python position_eval.py <fen1> [<fen2>...<fenN>]
OR
>> python position_eval.py file <filename>
(Note : filename must have the extension .fen)
  • Output : Current evaluation score and the best move. The FEN(s) along with the evaluation score is also written to a file called game_moves.log

plotter.py

You can also plot evaluation score vs number of moves using

>> python plotter.py

This will take data from game_moves.log

make_dataset.py

This file takes in a puzzle file in PGN format which contains Mate in 4+ puzzles, parses out the FEN strings, finds the optimal move sequence for mate and prints it to stdout and a file named dataset

JavaStockfish

A thin client for Stockfish. Comes in handy when we need to use Stockfish along with the object oriented goodness of Java. See Javadoc for detailed explanation. The functions currently implemented are :

  • Start the engine
  • Stop the engine
  • Get list of valid moves
  • Get best move
  • Send UCI commands to engine
  • Get raw dump from engine
  • Pretty print the board state
  • Get evaluation score

ChessVision

A simple tool which uses the amazing wkhtml* library to convert chess positions in FEN to either static HTML or PNG images. (Active development going on. More to come)

BitBoardGen

A basic module which converts FEN strings to Bit Boards. As of now, 12 Bit Boards are being created, one for each piece type.
