Since my opponent has taken the center position (1,1), my best strategic move is to take a corner. By placing my "O" in the top-left corner (0,0), I create multiple potential winning paths - along the top row, the left column, and the main diagonal. This is a standard counter to a center opening and gives me the most flexibility for future moves. Taking a corner maximizes my opportunities to create a fork later (a position with two simultaneous threats), which is a powerful winning strategy in Tic-Tac-Toe.
