If the center is taken, take a corner
Create two threats at once whenever possible
Block your opponent’s immediate winning move
Prioritize winning over blocking when you can win on your turn
Use forks to force your opponent into defense
Take the opposite corner if your opponent starts in a corner
If your opponent starts in the center, take a corner
If your opponent starts on an edge, take the center
Always look for lines with two of your marks and one empty space
Prevent your opponent from setting up forks
Play for the best available position each turn
Force draws when a win is not possible
