C62 Ruy Lopez: Steinitz Defense

C62 holds five named lines, all under the name Ruy Lopez. It leaves C60 (Ruy Lopez) with 3...d6. Material is no longer level at the end of two of its lines; the widest gap, three pawns in White’s favour, comes in Ruy Lopez: Steinitz Defense, Nimzowitsch Attack. That final move, by the d-pawn, covers c5 and e5 and opens a line for the bishop on c8 and the queen on d8.
