I'm choosing the center position (1,1) because:
1. It controls the most winning lines (4 possible ways - both diagonals, middle row, and middle column)
2. It's widely considered the strongest opening move in Tic-Tac-Toe
3. It forces the opponent to play defensively
4. It gives me the most flexibility for future moves
5. It maximizes my chances of creating a fork (two winning threats) later in the game
