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 winning opportunities as it's part of 4 possible winning lines: horizontal middle row, vertical middle column, and both diagonals. Starting in the center maximizes my flexibility for future moves and forces my opponent to respond defensively or risk giving me a winning opportunity. It's generally considered the strongest opening move in Tic-Tac-Toe strategy.
