I need to play at the top-right position (0,2) for two crucial reasons:

1. Defensive necessity: My opponent has 'O' at positions (0,0) and (0,1), creating an immediate threat across the top row. I must block position (0,2) to prevent them from winning on their next move.

2. Offensive setup: By playing at (0,2), I create two potential winning paths for my next turn:
   - A diagonal winning opportunity from top-right to bottom-left, as I already have 'X' at the center (1,1)
   - A vertical winning opportunity in the right column, as I already have 'X' at the bottom-right (2,2)

This move both prevents my opponent's immediate win and sets up multiple winning possibilities for me on my next turn.
