Building two bots to play Hexapawn against each other

Hexapawn is a two-player game starting with a chessboard of size N×M. Pawns exist on each side of the board and the goal is to advance a pawn all the way to the other end of the board. The standard pawn rules of chess apply. This is a variant of the Hexapawn recipe given in the easyAI library. Two bots will be created and pitted against each other. Let's create the code.

Create a new Python file and import the following packages:

from easyAI import TwoPlayersGame, AI_Player, \
        Human_Player, Negamax

Define a class that contains all the methods necessary to control the game. Start by defining the number of pawns on each side and the length of the board. Create a list of tuples containing the positions:

class GameController(TwoPlayersGame):
    def __init__(self, players, size = (4, 4)):
        self.size = size
        num_pawns, len_board = size
        p = [[(i, j) for j in range(len_board)] \...
