I believe there is not a winnning strategy. If both players know how to play, it will always end a draw.
If both players know how to play, the only way for a player to win is that the other player messes up.
Both players understand the game of Tic Tac Toe, so that would be a counter example
There is no winning strategy, you would have to force your oppenent to make a mistake.
You could do a recursive method that finds the best move after each move.
