Ruy López: Exchange Variation
Main Line
1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Bxc6 dxc6
Overview
White trades the bishop pair voluntarily on move 4 to inflict doubled c-pawns on Black — accepting positional damage to its own structure for a long-term strategic edge that becomes critical in the endgame. After 4...dxc6 5.O-O f6 or 5...Qd6, the structure is asymmetrical: White has a healthy 4-vs-3 kingside pawn majority while Black's queenside majority is crippled by the doubled c-pawns. Bobby Fischer popularized 5.O-O over the old 5.Nxe5 — his famous win as White over Bent Larsen in their 1971 Candidates Match made the Exchange respectable at top level. A classical strategy-focused weapon.
