I'm choosing the top-left corner (0,0) for several strategic reasons:
1. Corner positions are strong opening moves as they can contribute to multiple winning paths (diagonal and two edges)
2. With X in the center, taking a corner prevents them from immediately creating a fork situation
3. This position gives me potential to create a diagonal winning line (0,0 -> 1,1 -> 2,2) or edge-based wins along the top row or left column
4. It's a proactive move that forces X to play defensively rather than letting them control the game flow
