The 4 Step guarantees that you will never lose a game. Even though it's directed to when you do not start the round, it can work no matter who starts.

Most people think that Tic-Tac-Toe has a limitless (or at least 9) possible starting combinations, and you need to know how to counteract each possible position your opponent starts at. Wrong! Actually, there is only three starting positions.

Code: 
   x | x |   
 ------------
    | x |
 ------------
    |   |

Why? Because starting in one edge is the same as starting on any edge - starting in one outer middle is the same is starting in any outer middle - and obviously, the middle is the middle.

Now with the obviousness pushed aside, lets get down to the game.

Remember: x = you, o = opponent.



Step 1 - The Middle.

When someone starts in the middle, you must always go for a corner.

Code: 
     |   | x 
 ------------
    | o |
 ------------
    |   |

Now obviousness takes place. As long as you put your x in they're place to block they're attack, they can not win.

The middle is actually the worst way to begin an attack with!

Code: 
   x |   | x 
 ------------
  o | o | x  
 ------------
    |   |  o



Step 2 - The Corner.

When ever they go for a corner, you much go for the middle.

Code: 
   o |   |   
 ------------
    | x |
 ------------
    |   |

Step 2.5 - The Corner 2.

We all know that 'epic' move, where if you get 2 corners and your the first to go, you win. 2.5 can easily block that, no matter what corner they go for. All you have to do, is put an x in a vertical position next to your other x.

Code: 
  o |   |   
 ------------
    | x |
 ------------
    | x |  o

The 'epic' move needs 3 corners in 3 moves to work. Doing this forces them to put they're o beside your x's to stop your attack. Now if you play your cards right, you can't lose.

Code: 
   o | o |  x
 ------------
  x | x | o 
 ------------
  o | x |  o



Step 3.5 - The Outer Middle

If your opponent starts in the outer middle, you must go for the middle.

Code: 
     |   |   
 ------------
    | x | o 
 ------------
    |   |

Step 4 - The Outer Middle 2

You must now go for the sandwiching corner after your opponents move.

Code: 
   o |   | x < Sandwiching because it's in between the first and second o.
 ------------
    | x | o 
 ------------
    |   |

And again, you can not lose, as long as you don't do something stupid.

Code: 
   o |   | x 
 ------------
    | x | o 
 ------------
  o |   | x



Sub-steps!

Step 2.5 - The Corner 2.

Obviously, if they don't make the x's across from each other, you must block they're attack.

Code: 
   o |   |   
 ------------
  x | x |
 ------------
  o |   |

Step 4 - The Outer Middle 2

1)

If they make the 2 o's beside each other, block the attack.

Code: 
     |   | o 
 ------------
    | x | o 
 ------------
    |   | x

2) If they make the o's across from each other, put your x in an outer middle.

Code: 
     | x |   
 ------------
  o | x | o 
 ------------
    |   |



It looks a lot more complicated then it really is. Me and my friend made this up, and we tested it crapless for an hour and a half. It works, and ever game will 100% of the time end in:

1) You winning, or
2) (Most Common) Stalemating.

Feedback please :biggrin:.

As I said, it's simpler then it looks.



If Middle, go Corner.

If Corner, go Middle.

If Outer Middle, go Middle.
 
I don't know what you mean, GPow.

Anyway I made a small Tic-Tac-Toe program to practice on. Attached to first post.
 
Yeah, I sat for about 3 minutes waiting for the program to make a move against me.
 
Yeah but that bot doesn't use the 4 step. Too much programming, not enough effort :(.
 
After reading this tutorial, I have never lost a game of tic-tac-toe
 
Okay
