Taking the top-right corner (0,2) is the optimal move because:
1. It blocks opponent's immediate winning threat in the top row (0,0-0,1-0,2)
2. It creates two potential winning paths for me:
   - Diagonal line from top-right through center to bottom-left
   - Vertical line in the right column
This gives me multiple ways to win in the next move, forcing the opponent to block one but not both threats.
