The Middle Game in Chess. By Eugene Znosko-Borovsky. (Bell. 10s.

6d. net.)—This is a clever and interesting book, which begins with a discussion of the elements of chess and proceeds to consider the middle game, which is neglected in most treatises. The author's detailed criticisms of positions, selected from games by well-known players, are uncommonly stimulating. He proceeds systematically and shows that clear thinking is the secret of victory in chess as in other branches of human activity.
