I'm choosing the center position (1,1) for my first move because it provides the most strategic advantage in Tic-Tac-Toe. The center position is part of four possible winning lines - horizontal, vertical, and both diagonals. This gives me the maximum number of potential ways to create a three-in-a-row. Additionally, controlling the center makes it harder for my opponent to form winning combinations and provides me with more flexibility for future moves.
