If you are the second to go, it may be harder to win the game. If your opponent takes the center space, counteract that by placing your letter in a corner. If your opponent takes a corner space, take the middle space. This will force a draw in both cases. Winning is almost impossible unless a major mistake is made by your opponent. But, if your opponent starts on an edge that is not a corner, you can win. There is an exact science on how to win tic tac toe if this is the case: Put your first letter in the center. You can only claim victory if your opponent puts their letter on the other edge. If not, you will have to settle for a draw.
