PLAYER GOES SECOND - FIRST MOVE IN THE CENTER SQUARE

It would appear that there are 8x6x4x2=384 possible games here, considering all possible responses and countermoves. In practice, most games actually end quite quickly, and there are only 96 distinct legal board positions.

Game Analysis

Numbers next to each position correspond to the first move (5) followed by the player's moves, using: 

1 2 3
4 5 6
7 8 9
It is really only necessary to study "Player moves to a corner [1]" and "Player moves to an edge square [4]. By rotating the game board, all four sides and all four corners can be covered. Separate webpages are created for all possibilities. 
1 2 3        3 6 9        9 8 7        7 4 1
4 5 6   or   2 5 8   or   6 5 4   or   8 5 2
7 8 9        1 4 7        3 2 1        9 6 3
The twenty-four boards shown below times four rotations become 24x4 = 96 webpages.
