Rules 
1. Two teams, Black and White, take turns placing a stone 

(game piece) of their own color on a vacant point 
(intersection) of the grid on the board


2. Once placed, stones do not move

3. A vacant point adjacent to a stone is called a liberty for that 

stone

4. Connected stones formed a group and share their liberties

5. A stone or group with no liberties is captured

6. Black plays first

7. The first team to capture anything wins

colour of the player who has to play the turn (parameter 
colour), the sets of coordinates (i.e. sets of tuples) of all the 
black stones (parameter black) and white stones (parameter 
white) already positioned on the board, and returns the x, y 
coordinate (a tuple) of a free intersection where to place a new 
colour stone. The coordinates of the various positions of the 
board are those ones defined in "the board" in this paper.


def place_stone(colour, black, white):
    # study the board and calculate the 
    # best place where to position the stone
    return x, y  # the coordinates of the new stone

beginners so as to learn the basic rules of Go.
