Ruy Lopez: Exchange Variation

also known as: Spanish Exchange

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Bxc6

Named after

Not an eponym — named for the exchange 4.Bxc6, giving up the "Spanish bishop" at once.

Origin

Played by Emanuel Lasker with deadly effect around 1900; revived single-handedly by Bobby Fischer at the Havana Olympiad, 1966.

The story

Lasker used 4.Bxc6 to reach endgames where White's healthy kingside pawn majority ground Black down — his win over Capablanca at St. Petersburg 1914, in front of a stunned crowd, is the archetype. The line then gathered dust as "drawish" until Fischer uncorked it three times at Havana 1966, scoring wins with fresh ideas (5.O-O!) and proving the endgame was a real weapon, not a peace offer.

Why it matters

White trades the pride of the Spanish for structural profit: after ...dxc6 Black's queenside majority is crippled, so every simplification favors White. A permanent, teachable lesson in playing against pawn structure.
