I'm choosing position (0,1) which is the top-middle. This is the best move because:
1. It blocks the potential diagonal win from (0,0) to (2,2) that the opponent could set up
2. It creates two possible winning paths for me:
   - A horizontal win opportunity in the top row (I now have "O" at 0,0 and 0,1, and could win by playing at 0,2 next turn)
   - It maintains my vertical win opportunity in the left column (where I already have "O" at 0,0 and 2,0)
3. While the opponent has a threat in the middle row, after my move they would still need two moves to win, so I have time to complete my own winning line first
