The center controls the maximum number of potential winning lines - four in total (horizontal, vertical, and both diagonals). This gives me the most flexibility for future moves and forces my opponent to respond defensively. If my opponent takes a corner next, I can block their potential winning lines while simultaneously developing my own.

If they block one threat, I can pursue the other in my next move.
