The Marshall Attack is one of the oldest and most important openings in the history of chess. Black sacrifices a pawn against the Ruy Lopez in exchange for a long-lasting attack. Generations of the world's top players have fought on the Marshall battleground, but the final verdict on its soundness has not yet been reached. However, of one thing you can be sure: Black certainly has a lot of fun in trying to checkmate the white king! It is perhaps because of this reason that as White, many Grandmasters, including the world number one Gary Kasparov, have decided to avoid the issue altogether, preferring the more tranquil waters of Anti-Marshall systems. The ideas and strategies of both approaches are studied in depth here by a renowned openings theoretician. The Marshall Attack is an ideal weapon at all levels; contains full and up-to-date coverage of all the fashionable lines; is written by a leading openings expert.
