Learn to solve more complicated problems. Our new book includes combinations occurred in the games by well-known players, including outstanding masters of the past and the present. There are many specially composed positions, called studies. As in our previous book instructional material is arranged in sections of increasing complexity. The study of each section can be roughly estimated as adding 100 points to your rating. Thus our book should lead you up the rungs of chess mastery from a rating of 1600-1700 to a solid level of 2200 points or more which in practice corresponds roughly to that of a candidate master.
Of course with tactics alone you will not defeat all of your opponents, but without tactics nothing can be done in chess.
