I'm placing my O in the bottom-left position (2,0) for two key reasons:

1. Defensive value: This blocks my opponent from potentially creating a diagonal win through (0,2)-(1,1)-(2,0).

2. Offensive setup: More importantly, this creates two potential winning paths for me:
   - I can win along the left column if I get (1,0) in my next move
   - I can win along the diagonal from (0,0) to (2,0) if I get (1,0) next

This move applies pressure while preventing my opponent from developing their position. The bottom-left corner is strategically valuable as it connects with my existing O at the top-left (0,0).
