I'm choosing position 1,0 (middle-left) for my move because it gives me two potential winning paths. By placing my O here, I create a vertical threat in the left column (connecting with my existing O at 0,0) and a horizontal threat in the middle row. This forces my opponent to block one of these threats in their next move, but they cannot block both. If they block the vertical threat by playing at 2,0, I can win horizontally by playing at 1,2. If they block the horizontal threat by playing at 1,2, I can win vertically by playing at 2,0. This creates a fork situation that guarantees my win in the next move unless they create their own winning threat that I must block.
