I'm choosing the center position (1,1) for my first move because it's strategically the strongest opening position in Tic-Tac-Toe. The center gives me control of 4 potential winning lines - both diagonals, the middle row, and the middle column. By taking the center first, I maximize my winning opportunities while also preventing my opponent from claiming this powerful position. From here, I can respond effectively to wherever my opponent plays next.
