Taking the center position (1,1) is strategically strong in Tic-Tac-Toe. Since my opponent has played in the top-left corner, taking the center gives me the most opportunities to create winning lines. It puts me on two diagonals and both the middle row and middle column. If I don't take the center now, my opponent might take it on their next move, which would give them a significant advantage. The center position connects to all other positions on the board, maximizing my future options.
