"World War I began in midsummer 1914, bringing international chess to a virtual halt for more than four years.[9] Capablanca won tournaments in New York in 1914, 1915, 1916 (with preliminary and final round-robin stages) and 1918, losing only one game in this sequence.[29] In the 1918 event Marshall, playing Black against Capablanca, unleashed a complicated counterattack, later known as the Marshall Attack, against the Ruy Lopez opening. It is often said that Marshall had kept this secret for use against Capablanca since his defeat in their 1909 match;[30] however, Edward Winter discovered several games between 1910 and 1918 where Marshall passed up opportunities to use the Marshall Attack against Capablanca; and an 1893 game that used a similar line.[31] This gambit is so complex that Garry Kasparov used to avoid it,[32] and Marshall had the advantage of using a prepared variation. Nevertheless, Capablanca found a way through the complications and won."
