I'll place my O in the bottom-left position (2,0) to create a potential winning threat along the left column. This creates a vertical threat line from (0,0) to (2,0) that will force my opponent to block at the middle-left (1,0) on their next turn. By taking this corner position, I'm also preventing my opponent from creating a potential diagonal win. This move maximizes my strategic options while forcing my opponent to play defensively rather than continuing their own diagonal strategy.
