Tic Tac Toe Puzzle - Who can solve this fastest?

Most of us are aware of the game of Tic-Tac-Toe. A large square is divided into 9 equal sized small squares.
  • Two players taken turn in placing their mark in a small square.
  • The first one to get 3 marks in a horizontal, vertical or diagonal line wins.
  • A player will always place his or her mark in a line that already contains:
1. two of his own marks or
2. two of his opponent's marks (Here 1 has priority over 2).

Following image has game played by two friends and only the last mark has not been filled in -

    Something missing. Who plays the next move X or O?
    If X, the top right square is filled with an X, winning and blocking O from winning too.

    Either of player (O or X) with the next move will win by placing at right upper corner.

    I think O wins

    if x started the game, the sequence of game would have been different.
    the next move is 7th move and O started , so O wins

    The one who started first will win.
    Also seeing the pattern it is clear that one of the player didn't strictly followed all rules (ie made a mistake) so it is difficult to tell who started first.

    0 played the first move on a[2][1].

    suppose the matrix a[3][3] exists with top left square as a[1][1],
    then first move is by 0 on a[2][1], second move by X on a[2][2],
    third move by 0 on a[1][2], fourth move by X on a[3][2],
    fifth move by 0 on a[1][1], now X gets tricked and puts X on a[3][1],
    so on next move 0 on a[1][3] is winning move !!
