I'm placing my X in the bottom-right corner (2,2) for a strong strategic position. This move sets up two potential winning paths for my next turn: 
1) Completing the diagonal from center (1,1) to bottom-right (2,2), needing only top-right (0,2)
2) Creating a potential winning path along the right column, needing middle-right (1,2)

By creating two potential winning lines, I force my opponent to defend against multiple threats on their next move, which improves my chances of setting up a winning position. The opponent has already blocked one diagonal with their O in the top-left, so developing this alternate diagonal gives me the strongest position.
