Suppose that, instead of playing in your turn, you have to submit in advance, an ordered list of the 9 board positions. Then a computer plays for you by using, whenever it is your turn, the leftmost position that is still untaken. For example, suppose you are "X" and you play first. Then the computer puts "X" in the first position on your list. Then the opponent plays. Then the computer puts "X" in the second position on your list (if it is still free), otherwise it pust "X" in the third position. And so on.
Note that the other player can see your list and plan accordingly. Can you force a tie when you play first? When you play second?
