I'm choosing the center position (1,1) for my first move because it provides the maximum strategic advantage. The center connects to 8 other squares and gives me control of 4 potential winning lines: the horizontal middle row, the vertical middle column, and both diagonals. This is the optimal opening move in Tic-Tac-Toe as it creates the most opportunities to form a winning line while also blocking my opponent from controlling the center. From this position, I can respond effectively to any move my opponent makes next.
