I'm choosing the center position (1,1) for my first move as X. The center is strategically valuable in Tic-Tac-Toe because it gives me the most opportunities to create winning lines - it's part of 4 possible winning combinations (horizontal middle row, vertical middle column, and both diagonals). Starting in the center puts me in a strong position to respond to my opponent's next move, and it's generally considered one of the strongest opening moves in Tic-Tac-Toe.
