Initialize game board (table using pre-defined size)
Fill the table with empty intersections

Set firstPlayerTurn to true
Set the game state as onGoing

While game onGoing:
	1. Display current game state
	2. Ask current player for input (move or pass)
	3. If input is move (x, y):
		a. If move is valid (not occupied and no self-capture):
			i. Place stone at (x, y)
			ii. Check if any opponent's stones are captured:
				- For each neighbouring intersection (up, down, left, right):
					- If neighbouring intersection has opponent's stone and no liberties:
						- Remove the stone and add a captured count to the player's score
			iii. Set firstPlayerTurn to false
		b. Else:
			i. Display error message and prompt the player to make another choice
			ii. Return
	4. Else if input is pass:
		a. Set firstPlayerTurn to false
	5. End the game by setting onGoing to false when:
		a. All intersections are occupied by stones OR
		b. Both players resign by passing his turn consecutively

Calculate and display the final score:
	Count the number of stones each player has on the board
	Add their captured stones to the total score

Determine and announce the winner:
	The player with the higher score wins
	If the scores are tied, the game is a draw
