FalseEach variant has it's own specyfic rules.
- Validate and generate moves
>>> board.push_uci("31-22")
ValueError: 31-22 is correct, but not legal in given position.
Legal moves are: ['31-27', '31-26', '32-28', '32-27', '33-29', '33-28', '34-30', '34-29', '35-30']
>>> list(board.legal_moves)
['31-27', '31-26', '32-28', '32-27', '33-29', '33-28', '34-30', '34-29', '35-30']- Reads and writes fen strings
>>> board = get_board('standard', "W:W4,11,28,31,K33,K34,38,40,K41,43,K44,45,K46,47:BK3,21,27,32")
>>> board.fen
'[FEN "W:W4,11,28,31,K33,K34,38,40,K41,43,K44,45,K46,47:BK3,21,27,32"]'- Has simple engine
>>> from draughts.engine import AlphaBetaEngine
>>> engine = AlphaBetaEngine(depth=5)
>>> engine.get_best_move(board, with_evaluation=True)
Move: 28->37, 3.0- Allows to play against AI.
- Allows to play vs another player. (on the same computer)
- Allows to test and find bugs in your engine.
python -m draughts.serverExample with simplest possible engine.
>>> from draughts.server import Server
>>> import numpy as np
>>> get_best_mv = lambda board: np.random.choice(list(board.legal_moves))
>>> server = Server(get_best_move_method=get_best_mv)
>>> server.run()
