Chess Strategy. By Eduard Lasker. Translated by.,J. Du Mont. (G.

Bell and Sons. 5s. net.)—Noininally a revised second edition, this is in reality a new book, with a chapter for beginners and many new games with annotations. One of the most interesting of these is a game between Mr. G.A. Thomas and the author, in which Mr. Thomas adopted an irregular opening and took instant advantage of a mistake on the part of Mr. Lasker to initiate a decisive attack on the champion's broken ranks. We can cordially recommend the book, with its insistence on definite principles and its intelligent treatment of the problem of the pawns.
