Since my opponent has taken the center position (1,1), I'll place my mark in the top-left corner (0,0). When the opponent controls the center, taking a corner is strategically strong as it creates potential winning opportunities along multiple lines - both the top row and the left column, as well as setting up a potential diagonal. Corner positions generally provide more flexibility than edge positions in this scenario, allowing me to develop multiple threats in future moves. This is a standard counter to the center opening in Tic-Tac-Toe.
