I'm choosing the bottom-right corner (2,2) to create two potential winning lines. By placing my 'X' here, I establish a diagonal threat from top-left to bottom-right, and also create the beginning of a potential winning line along the right column and bottom row. This gives me multiple paths to victory and forces my opponent to block one of these threats, which will likely give me an advantage in subsequent moves. The corner position is strategically strong as it contributes to both a diagonal and two straight lines.
