Now I am a master at winning tic tac toe

[@Ulthar_Cat]

If both play perfectly, it should be a draw I think.

[@ScienceMom]

That's right! The first player has the advantage and plays to win - the second player is playing for a draw and can only win if the first player makes a mistake. If both play perfectly then it will be a draw every time.
