Berlin Defense

Strategic Summary & Main Idea

The Berlin Defence meets the Ruy Lopez with 3...Nf6, attacking e4 instead of defending e5, and became famous as Kramnik's wall against Kasparov in 2000. It is the most solid defence to 1.e4 e5: the position after 3...Nf6 measures +0.20, and the Berlin Wall endgame, without queens and without Black castling, +0.19. The attempts to avoid the endgame do not yield more either — 4.d3 measures +0.22 — and what the measurement exposes are the mistakes. The capture 6...Nxb5?? in the 5.Re1 line measures +9.11, and 5...Nxf2, +3.82.

The pawn structure this opening produces

The Berlin produces two completely different structures, depending on whether White accepts or avoids the endgame. In the Berlin Wall, after 4.O-O Nxe4 5.d4 Nd6 6.Bxc6 dxc6 7.dxe5 Nf5 8.Qxd8+ Kxd8, the queens come off, Black's king sits on d8 and the structures are asymmetrical: White has a kingside majority, with the pawn on e5, and Black has doubled pawns on c6 and c7 and the bishop pair. White's plan is to advance the majority with f4 and g4 and create a passed pawn; Black's plan is to blockade with king and bishops and use the queenside majority in the endgame. The other structure comes from 4.d3, which avoids the endgame: the e4 pawn is defended, the game goes on with queens and the position becomes a slow Italian, with c3, Nbd2 and the knight manoeuvre to g3. Black answers with ...Bc5 and ...d6 and the play is manoeuvring. In both structures White has little advantage and Black little weakness — which makes the Berlin a defence where the result depends more on endgame technique than on preparation.

Frequently asked questions

Is the Berlin Defence a draw?

No, but it is the most solid defence to the Ruy Lopez: +0.20 after 3...Nf6, and +0.19 in the Berlin Wall endgame. White keeps a small, lasting edge, and Black must know how to defend the endgame with the king in the centre and doubled pawns. The result depends on technique, not theory.

How to avoid the Berlin Wall endgame?

With 4.d3, the Anti-Berlin, which measures +0.22 — practically the same number as the endgame, with queens on the board. The other way out is 5.Re1 after 4.O-O Nxe4, which measures +0.33 and is the highest evaluation among this entry's main lines.

What is the most dangerous trap in the Berlin?

In the 4.O-O Nxe4 5.Re1 Nd6 6.Nxe5 line, taking the bishop with 6...Nxb5 loses the queen: 7.Nxc6+ is a discovered check from the e1 rook, and the knight takes d8 next move. The position measures +9.11. The correct move is 6...Be7, which blocks the e-file.

Common Mistakes & Where Most Amateurs Go Wrong

• 01 Taking the bishop with 6...Nxb5?? in the 5.Re1 Nd6 6.Nxe5 line. The e5 knight moves with a discovered check from the rook, 7.Nxc6+, and once Black gets out of check it takes the queen on d8: +9.11. The line: 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.O-O Nxe4 5.Re1 Nd6 6.Nxe5 Nxb5 7.Nxc6+ +9.11
• 02 Saving the attacked knight with 5...Nxf2? against 5.Re1. The piece goes for a pawn: 6.Kxf2, and White is a piece up with the e-file open against Black's king, +3.82. The line: 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.O-O Nxe4 5.Re1 Nxf2 +3.82
• 03 Recapturing with 6...bxc6? in the 5.Qe2 Nd6 6.Bxc6 line. The b-pawn leaves e5 undefended, and 7.Qxe5+ Qe7 regains the material with Black's structure worse: +1.05. The line: 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.O-O Nxe4 5.Qe2 Nd6 6.Bxc6 bxc6 7.Qxe5+ Qe7 +1.05
