The American Brilliance. U.S. Champion for 27 unbroken years and the inventor of the Marshall Attack, one of the most aggressive replies to the Ruy Lopez ever devised.
Frank James Marshall held the United States Championship for an unbroken twenty-six years, from 1909, when he defeated Jackson Showalter, to 1936, when he voluntarily gave up the title rather than defend it again. He was the kind of player audiences came specifically to see. His combinations were so spectacular that opponents reportedly sometimes showered him with gold coins after games. He devoted years of preparation to a single weapon against the Ruy Lopez, unveiled it against Capablanca in 1918, and lost, but the Marshall Attack remains one of the most respected counter-systems in opening theory more than a century later. He founded the Marshall Chess Club in New York in 1915; it is still active today and remains one of the great chess institutions in the United States.
Notable: U.S. Champion 1909–1935. Invented the Marshall Attack in the Ruy Lopez. Founded the Marshall Chess Club (1915), still operating in Manhattan.
