I'm placing my "O" at the bottom-left corner (2,0) to set up a potential win in the left column. With an "O" already in the top-left (0,0), placing another in the bottom-left creates a strong threat along the left column. If my opponent doesn't block at (1,0) in their next move, I can win by completing the left column. Additionally, taking a corner position is strategically valuable in Tic-Tac-Toe as it limits my opponent's options. While my opponent has established a diagonal with X's at (1,1) and (2,2), controlling the left column forces them to play defensively rather than pursuing their own winning strategy.
