I'm placing my O at position (2,0) to create a potential winning line along the left column. With my existing O at (0,0), this move sets up a threat along the left column that my opponent will likely need to block at (1,0) in their next turn. This is a strategic move that begins to establish control of the board while preventing any potential fork situations the opponent might create. If my opponent doesn't block the left column, I can win on my next move by placing at (1,0).
