This is a practical chess book for all players, from the beginner to the expert. It contains over 300 actual game situations in diagram form to test the player's chess proficiency, challenge his brain, present him with new winning ideas, and add skill to his game. These stimulating chess problems have been specifically selected by I.A. Horowitz, three-time U.S. Open Champion, editor of Chess Review, and current chess editor for the New York Times.
