The undisputed number-one way to learn to win a game of chess, a centuries-old tradition, is this: Play chess games and learn from experience. Other methods may help the learning process along, but the best way is to play chess.
Or course a chess tutor or book may help you. A new book for beginners uses new ideas in teaching a newcomer how to win: Beat That Kid in Chess. Perhaps this is the second-best way to learn, reading and applying the lessons in that book.
