How to use these guides

Play a few matches while focusing only on the rules. Then choose one strategic goal—such as controlling the center or spotting threats early—and practice it consciously across several games.

TableDuel lets you start another match immediately, so you can test a different approach after a mistake. With a friend you can discuss the same position together; computer difficulty levels provide a gradual challenge when you practice alone.
