The center position (1,1) is strategically the strongest opening move in Tic-Tac-Toe for several reasons:
1. It provides maximum flexibility with four potential winning lines (horizontal, vertical, and both diagonals)
2. It controls the center of the board, which is a key position
3. It prevents my opponent from taking this advantageous position
4. From the center, I can respond to my opponent's moves more effectively regardless of where they play next
