Start in the center if available
If the center is taken, take a corner
Create a fork whenever possible
Block your opponent’s fork
Take the winning move immediately
Block your opponent’s immediate winning move
Use opposite corners against a center opener
Force your opponent into defensive moves
Aim to control two lines at once
Prioritize center, then corners, then sides
Play to set up multiple threats
Never ignore a chance to win on your turn
Never allow an unblocked two-in-a-row
If both players play perfectly, expect a draw
