I'm choosing the center position (1,1) for my first move because it provides the maximum 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 most opportunities to create a three-in-a-row. Taking the center also prevents my opponent from using this valuable position and forces them to play more defensively. As the first player with 'X', controlling the center gives me the best chance to win quickly.
