Tic-Tac-Toe-Squared

The game is described fairly easily: Its Tic-Tac-Toe inside Tic-Tac-Toe.

For those who are familiar with ultimate-tic-tac-toe it’s basically the same game with some smaller changes. For those who have no clue, here are the rules:
The first player may play his “X” wherever he likes. According to the position of the “X”, the second player has to play his “O” in the corresponding field. For example, if I play my “X” in the upper right corner the second player has to play his “O” in the upper right Tic-Tac-Toe field.
If a field is won, there is no way for it to be regained. In contrast to ultimate-tic-tac-toe however, you are allowed to be send to an already won Tic-Tac-Toe field. If this is the case, the current player then has the opportunity to tactically guide the opponent. If a player lands on a completely full field he may play in his preferred field.
The game is won when you win three fields in a row.
