Make and undo moves
>>> board.push_from_str("37-32")
>>> board.push_from_str("14-19")
>>> board.push_from_str("32-28")
>>> board.push_from_str("19-23")
>>> board.pop() # undo last move
>>> board.push_from_str("19-23")
>>> board.push_from_str("28x19")

Generate legal moves and validate moves
>>> board.push_from_str("10x42")
Move: 10->42 is correct, but not legal in given position.
Legal moves are: [Move: 36->31, Move: 37->32, Move: 37->31, Move: 38->33, Move: 38->32, Move: 39->34, Move: 39->33, Move: 40->35, Move: 40->34]
>>> list(board.legal_moves)
[Move: 36->31, Move: 37->32, Move: 37->31, Move: 38->33, Move: 38->32, Move: 39->34, Move: 39->33, Move: 40->35, Move: 40->34]
Generate fen string and load board from fen string
>>> board =Board.from_fen("W:W4,11,28,31,K33,K34,38,40,K41,43,K44,45,K46,47:BK3,21,27,32")
Board initialized with shape (10, 10). (base.py:109)
>>> board.push_from_str("28-37")
>>> board.fen
'[FEN "B:W4,11,31,K33,K34,37,38,40,K41,43,K44,45,K46,47:BK3,21,27"]'
American checkers
>>> from draughts.american import Board
>>> board = Board()
Board initialized with shape (8, 8). (base.py:108)
>>> board
. b . b . b . b
b . b . b . b .
. b . b . b . b
. . . . . . . .

UI
- Allows to play against AI.
- Allows to play vs another player. (on the same computer)
- Allows to test and find bugs in your engine.
from draughts.server import Server
Server().run()
Use for testing your engine.
Example with simplest possible engine.
>>> server = Server(get_best_move_method=lambda board: np.random.choice(list(board.legal_moves)))
>>> server.run()
INFO: Started server process [1617]
INFO: Waiting for application startup.
INFO: Application startup complete.
INFO: Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
It is as simple as that!
