I'm choosing the center position (1,1) for my first move because it's strategically optimal in Tic-Tac-Toe. The center position gives me the most opportunity to create winning lines as it's part of 4 possible winning combinations: horizontal middle row, vertical middle column, and both diagonals. Starting in the center provides maximum flexibility for my future moves and forces my opponent to play defensively if they want to prevent me from creating multiple threats simultaneously.
