I'm choosing the center position (1,1) for my first move. This is generally considered the strongest opening move in Tic-Tac-Toe because it gives me the most opportunities to create winning lines - I can potentially form a row, column, or either diagonal from this position. The center position is part of 4 possible winning combinations (horizontal middle row, vertical middle column, and both diagonals), which is more than any other position on the board. By taking the center first, I maximize my strategic options for subsequent moves.
