def game_play_ai():
"""
This is the main mechanism of the human vs. ai game play. You need to
implement this function by taking helps from the game_play_human()
function.
For a given board situation/state, you can call the ai function to get
the next best move, like this:
move = ai.get_next_move(board, turn)
where the turn variable is a color 'black' or 'white', also you need to
import ai module as 'import gameai as ai' at the beginning of the file.
This function will be very similar to game_play_human().
# UNCOMMENT THESE TWO LINES TO TEST ON MIMIR SUBMISSION
This is the main mechanism of the human vs. human game play.
Use this function to write the game_play_ai() function.
