Taking the center position (1,1) is a strong strategic move in Tic-Tac-Toe. The center gives me access to four potential winning lines - both diagonals, the middle row, and the middle column. My opponent has placed their X in the bottom middle (2,1), and by taking the center, I can prevent them from establishing control of the middle column. Additionally, the center position will allow me to respond effectively to my opponent's next move regardless of where they play, as I'll have multiple strategic pathways to develop.
