I'm choosing the center position (1,1) for my first move because it's strategically the strongest opening in Tic-Tac-Toe. From the center, I control four potential winning lines - the middle row, middle column, and both diagonals. This maximizes my winning opportunities while preventing my opponent from taking this advantageous position. The center also allows me the flexibility to respond to any move my opponent makes next, giving me the best chance to develop a winning strategy as the game progresses.
