Looking at the board, I have an X in the center (1,1) and in the bottom-left (2,0). My opponent has O in the top-right (0,2) and middle-right (1,2). 

If I place my X in the bottom-right (2,2), I'll create a diagonal line from top-left to bottom-right. This would give me X in positions (0,0), (1,1), and (2,2). While this position doesn't create a win immediately, it sets up a potential win on my next turn.

Wait - I noticed the board differently. I actually have X in the bottom-left (2,0) and middle (1,1), not the top-left. By placing X in position (2,2), I'll complete a diagonal line from the center to the bottom-right corner, winning the game immediately with a diagonal line from (0,0) to (2,2).
