Splendid key and main variation (a . P-B 5 ch) with good supporting Play. One of the most famous and most analysed attacks in chess is the Marshall attack in the Ruy Lopez. It was first played by the great American attacking player Frank J. Marshall against Capablanca ; Marshall discovered the variation, analysed it carefully and waited his chance, which came in the Manhattan Tournament in 1918. Capa was taken completely by surprise and had to face the line unprepared ; his natural genius carried him through and, despite all Marshall's midnight oil, Capablanca won-a mar- vellous feat. Since then innumerable games have been played without any final verdict being reached ; here is a recent game where Black is more successful than Marshall was.

Ruy Lopez. White plays to build up a long-term attack based on

the lac+ hat after P-Q 3; 9 P-Q 4 he will have an advantage in space. It is characteristic of the opening, however,

that White's queen's side development is slow and this sacrifice

attempts x toP open up the position and exploit this feature.
