The Marshall Attack was introduced by Frank Marshall in a famous game against Capablanca in New York in 1918. According to legend, Marshall saved this prepared innovation for eight years before getting the chance to play it against Capablanca.
Although Marshall was not successful in this famous game, the attack has captured the attention of the chess world, and elite players have played variations of it for more than a century. For example, in game eight of the world championship in 2004, GM Vladimir Kramnik succumbed to Black's attack by GM Peter Leko.
