To win as fast as possible, I should try to create two possible ways to win in the next move. Currently, my 'X' symbol is in the top-right corner. I can place my next 'X' in position 0,0 to potentially create a row of 'X's along the top and also prepare for a potential diagonal line from top-left to bottom-right. This move also blocks the opponent's potential three 'O's in a row.
