Tic Tac Toe – Creating Unbeatable AI with Minimax Algorithm (towardsdatascience.com)

Wouldn't it be better to just use a magic square[1]?

Is minimax more efficient or is the author simply using the game to describe the concept behind the algorithm?

Magic square could be used there and it might be even faster but the goal of this article was to show the underlying Minimax algorithm.
