Ruy Lopez Marshall Attack
Frank Marshall's 8...d5 pawn sacrifice and the full anti-Marshall survival kit — ten drills covering the main 17.Nd2 attack, classical 15.Be3 lines, the old Spassky 15.Qf3 endgame, and every modern White anti-Marshall (8.h3, 8.a4, 8.d3, 8.d4 and the early 6.d3 move-order).
The Marshall Attack is Black's most ambitious answer to the Ruy Lopez — sacrifice a pawn on move 8 for a long-lasting kingside initiative that has stood up against every world champion from Capablanca to Carlsen. This pack drills the modern main lines (17.Nd2 with ...Bf5, classical 15.Be3 ...Bg4, the old Spassky queen-trade) AND every anti-Marshall White uses to dodge the fight: 8.h3 with the Karpov regrouping, 8.a4 sharp endgame, 8.d3 Closed-Ruy transposition, 8.d4 centre tension, and the early 6.d3 sidestep. Forty exam positions hammer in the move-order subtleties — Qh4 vs Qh3, Rae8 vs Bg4, ...Bb7 vs ...b4 — so you can answer every White try with confident, prepared theory.
