I'll place my O at the middle-left position (1,0). This will complete a vertical line of three Os in the leftmost column (positions 0,0, 1,0, and 2,0), giving me an immediate win. I already have Os at the top-left (0,0) and bottom-left (2,0), so this move completes my winning strategy. While there are other valid moves available, none of them would result in an immediate win, and my goal is to win as quickly as possible.
