I'm choosing the top-left corner (0,0) as my first move. Since the opponent has taken the center, taking a corner is a strong strategic choice. This gives me potential winning lines along the top row, left column, and the diagonal. By taking a corner, I'm setting up multiple potential winning paths. If the opponent doesn't block my diagonal threat on their next turn, I could set up a fork that forces them to defend in multiple directions simultaneously. The corner positions are generally strong in Tic-Tac-Toe, especially when the center is already taken by the opponent.
