The center position (1,1) is strategically the strongest opening move in Tic-Tac-Toe. From the center, I can potentially form winning lines in four different directions: horizontal, vertical, and both diagonals. This maximizes my winning opportunities while also preventing my opponent from taking this powerful position. If my opponent responds by playing in a corner, I'll have multiple strategic follow-up options, and if they play on a side, I can often force a win by creating a two-way threat.
