C63 Ruy Lopez: Schliemann Defense
C63 holds nine named lines, all under the name Ruy Lopez. It leaves C60 (Ruy Lopez) with 3...f5. Material is no longer level at the end of four of its lines; the widest gap, three pawns in White’s favour, comes in Ruy Lopez: Schliemann Defense, Exchange Variation. That final move, by the f-pawn, covers e4 and g4.
