I'm choosing the center position (1,1) for my first move because it provides the most strategic advantage in Tic-Tac-Toe. From the center, I can potentially form winning lines in four different directions: horizontal, vertical, and both diagonals. This maximizes my winning opportunities and gives me the best control of the board. The center position is typically considered the strongest opening move in Tic-Tac-Toe for this reason.
