I'm choosing the bottom-left position (2,0) for several strategic reasons:
1. Defense: It blocks X from potentially creating a diagonal line from top-right to bottom-left
2. Offense: It creates two potential winning paths for O:
   - A vertical line in the left column (already have 0,0, now 2,0)
   - A diagonal line from top-left to bottom-right (already have 0,0, now 2,0)
This dual-purpose move both defends against X and creates multiple winning opportunities for O.
