The Marshall Attack is a variation of the Ruy Lopez, catalogued as ECO C89. The line runs 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 O-O 8. c3 d5, reaching the position shown below after 16 half-moves.
Both sides have pawns in the centre (White on e4, Black on d5 and e5), and one pawn capture is available, so the structure has not settled yet. Development is level at two minor pieces each. It is White to move after eight moves. Both kings have castled kingside, so play tends to shift to the centre and the opposite flank.
On the Ruy Lopez generally: One of the oldest and most classical openings. White develops rapidly and puts pressure on Black's center.
