I'll place my X in the bottom-right corner (2,2) for two strategic reasons:

1. This creates a diagonal threat line from my center X (1,1) to this new position, forcing my opponent to block in their next move.

2. It opens up two potential winning paths for me - both the diagonal and the right column.

With my X in the corner position, I'm setting up multiple threats rather than just blocking my opponent's potential moves. If they don't block my diagonal, I can win on my next turn. If they do block it, I'll still have other winning opportunities to develop.
