Since my opponent has taken the center position (1,1) with their X, I'll place my O in the top-left corner (0,0). This is a strategic opening response that gives me multiple potential winning paths. From this position, I can potentially create winning lines along the top row, the left column, or the diagonal from top-left to bottom-right. Taking a corner also forces my opponent to play defensively in many scenarios, which may give me more control over the game's progression.
