Project description

Stockfish

Implements an easy-to-use Stockfish class to integrates the Stockfish chess engine with Python.

Install

$ pip install stockfish

Ubuntu or Debian

# apt install stockfish

Mac OS

$ brew install stockfish

Features and usage examples

Initialize Stockfish class

You should install the stockfish engine in your operating system globally or specify path to binary file in class constructor

from stockfish import Stockfish

stockfish = Stockfish("/Users/zhelyabuzhsky/Work/stockfish/stockfish-9-64")

There are some default engine's settings:

{
    "Write Debug Log": "false",
    "Contempt": 0,
    "Min Split Depth": 0,
    "Threads": 1,
    "Ponder": "false",
    "Hash": 16,
    "MultiPV": 1,
    "Skill Level": 20,
    "Move Overhead": 30,
    "Minimum Thinking Time": 20,
    "Slow Mover": 80,
    "UCI_Chess960": "false",
}

You can change them during your Stockfish class initialization:

stockfish = Stockfish(parameters={"Threads": 2, "Minimum Thinking Time": 30})

Set position by sequence of moves:

stockfish.set_position(["e2e4", "e7e6"])

Set position by Forsyth–Edwards Notation (FEN):

stockfish.set_fen_position("rnbqkbnr/pppp1ppp/4p3/8/4P3/8/PPPP1PPP/RNBQKBNR w KQkq - 0 2")

Get best move

stockfish.get_best_move()
d2d4

Get best move based on a time constraint

stockfish.get_best_move_time(1000)

Time constraint is in milliseconds

e2e4

Check is move correct with current position

stockfish.is_move_correct('a2a3')
True

Set current engine's skill level:

stockfish.set_skill_level(15)

Set current engine's depth:

stockfish.set_depth(15)

Get current engine's parameters:

stockfish.get_parameters()
{'Write Debug Log': 'false', 'Contempt': 0, 'Min Split Depth': 0, 'Threads': 1, 'Ponder': 'false', 'Hash': 16, 'MultiPV': 1, 'Skill Level': 20, 'Move Overhead': 30, 'Minimum Thinking Time': 20, 'Slow Mover': 80, 'UCI_Chess960': 'false'}

Get current board position in Forsyth–Edwards notation (FEN):

stockfish.get_fen_position()
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1

Get current board visual

stockfish.get_board_visual()

Get current board evaluation in centipawns or mate in x

stockfish.get_evaluation()

Positive is advantage white, negative is advantage black

{"type":"cp", "value":12}
{"type":"mate", "value":-3}

Get current major version of stockfish engine

stockfish.get_stockfish_major_version()
11

$ python setup.py test
