Ruy López: Open Defense (Open Spanish)
Main Line
1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Nxe4
Overview
The Open Ruy López — Black grabs the e-pawn on move five and fights for the center with ...b5, ...d5, and ...Be6. Piece-led tactical chess instead of slow Closed Spanish maneuvering. Korchnoi's signature weapon against Karpov in the 1978 and 1981 world championship matches. The classical 9.c3 Bc5 main line, the Dilworth Attack (...Nxf2!), and the modern 9.Nbd2 Anti-Open Spanish are the three theoretical pillars.
