An unbeatable tic tac toe

By utilising 18 different priority tables, a "special moves" data file containing 19 prefabricated special moves and blocks, this tic tac toe game allows the computer to play flexibly and win in the shortest number of steps. Virtually Unbeatable. Special moves and priority tables can be added or deleted at will. Use number pad to play. Numlock on. Please inform me if you manage to beat it. Might be a bug :)
