By placing my O in the top-left corner (0,0), I create three potential winning lines - the top row, the left column, and the diagonal from top-left to bottom-right. This maximizes my options for future moves and forces my opponent to play defensively. If they don't block one of my potential threats on their next turn, I'll have multiple paths to victory.
