Ruy Lopez: Berlin Defense

also known as: Berlin Wall · Spanish, 3...Nf6

1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6

Named after

The Berlin school of the mid-1800s — the "Pleiades" masters around Ludwig Bledow and Paul Rudolf von Bilguer, who analyzed 3...Nf6 in their handbooks.

Origin

A respected 19th-century defense that slept for a century until Vladimir Kramnik resurrected it in London, 2000.

The story

Kramnik needed a way to neutralize Garry Kasparov — the most feared attacking player alive — in their 2000 World Championship match. He dusted off the antique 3...Nf6 and steered into the queenless "Berlin endgame" (4.O-O Nxe4 5.d4 Nd6 6.Bxc6 dxc6 7.dxe5 Nf5 8.Qxd8+ Kxd8). Kasparov battered it for the whole match, won nothing, and lost the crown without winning a single game. Journalists called it the Berlin Wall, and this time the wall went up. It has been an elite mainstay ever since.

Why it matters

Black accepts doubled pawns and loses castling rights but gets the bishop pair and a fortress-like structure. It converted the Ruy Lopez from an attacking arena into a test of endgame technique — and shifted opening fashion at the top for two decades.
