This is all wrong. The second move for X, unless O blocked it already, or started off in the centre should be the lower right corner. That way, O will use the centre to block, and then X goes in a third corner, thus sealing the game.76.29.225.28 04:59, 23 July 2013 (UTC)

- Playing as X, you start in the upper left corner. O plays in any square other than the lower right corner (They might be able to block if they play the centre, depending on whether they anticipate this move). Then, when O blocks the centre, you play the upper right or lower left corner, depending on where O has played before, thus making it impossible to block because they only get one move. The only time this ever fails is when O knows what X is doing after the first move.
There is an error in the drawing when starting with (numpad coordinates) X7, O9, X1, O4, X3: Both O5 and O6 have the same picture. --Chtz (talk) 09:11, 23 July 2013 (UTC)
