Playing in the top-left corner (0,0) is a strong strategic move. Since I already have the center position (1,1), placing my X in the corner sets up two potential winning lines - the diagonal from top-left to bottom-right and potentially the top row or left column. This creates multiple threats for my next move. If my opponent doesn't block carefully, I could create a "fork" situation in my next turn, where I'll have two possible ways to win simultaneously. Corner play is generally strong in Tic-Tac-Toe, especially when combined with center control, as it maximizes my winning opportunities.
