I'll place my O in the bottom-left corner (2,0) for two strategic reasons:

1. This creates two potential winning paths for me:
   - A vertical line in the left column (connecting with my existing O at the top-left)
   - A potential diagonal win from bottom-left to top-right (which I can complete if I get position 1,2 next)

2. This move blocks a potential future threat where my opponent could try to create a diagonal or vertical winning path.

By placing my O at position 2,0, I'm maximizing my chances of creating multiple winning opportunities in future moves while preventing my opponent from developing a strong position in that corner.
