I'm placing my X in the bottom-right corner (2,2) for strategic advantage. This creates two potential winning lines: the diagonal from top-left to bottom-right (which already has my X in the center), and the right column. By creating these two threats simultaneously, I force my opponent to block one of them in their next move, which could leave the other line open for me to win. Additionally, this is a strong counter to the opponent's opening move in the top-left corner, as it establishes my presence in the opposite corner.
