I'll place my "O" at the bottom-left position (2,0). This creates two potential winning paths for me: 
1. A diagonal opportunity from bottom-left (2,0) to top-right (0,2)
2. A vertical opportunity down the left column from (0,0) to (2,0)

By creating two potential winning lines at once, I force my opponent to block one of them, which will allow me to win through the other line in my next move. This is an optimal fork strategy in tic-tac-toe.
