The power-packed teams of the Manhattan and Marshall Chess Clubs, which always face each other in the final round of the Metropolitan Chess League, clashed once more in the rooms of the defending and pereniallly successful Manhattan champions. The Marshall challengers, with a line-up that probably could have beaten any other team in the country except the Manhattans, made a close fight of it before succumbing by 6 – 7. Manhattan winners were William Lombardy, Bobby Fischer, Daniel Beninson and Walter Shipley, while full points for the Marshall Club were registered by Carl Pilnick, Saul Wachs and A. E. Santasiere. Draws (Manhattan players mentioned first) were registered as follows: Arthur Bisguier vs. Sidney Bernstein; Abe Turner vs. Herbert Seidman; I. A. Horowitz vs. James Sherwin; Dr. H. Sussman vs. John W. Collins; George Shainswit vs. T. A. Dunst; and <Karl Vine> vs. Edward Lasker.
