The Ruy Lopez: 1.e4 e5 2.Nf3... d6 arises after 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 d6 and falls under ECO code C71. A great deal of the early maneuvering in the Spanish revolves around White's recurring threat to capture on e5 with the knight, Black's efforts to prevent it, and White's attempts to renew the pressure. By supporting e5 with a pawn, 4...d6 neutralizes that threat permanently. This move also frees the light-squared bishop to develop, but it blocks the diagonal the king's bishop needs after 1...e5 and turns the latent pressure from White's bishop on the knight into a genuine pin. Known as the "Modern Steinitz" or "Deferred Steinitz" Defence, this setup improves on Steinitz's original idea of 3...d6 (the "Old Steinitz"), because with 3...a6 4. Ba4 already played, Black can break the pin at will with ...b5. This distinction matters when White tries 5. d4?!, which on the surface looks reasonable for the same reasons it works against the 3...d6 move order. Since ...d6 added pawn defense to e5 but effectively removed the knight as a defender by pinning it, White hopes to win the pawn via dxe5 dxe5 Nxe5. If Black instead captures on d4, 5...exd4? 6. Nxd4 threatens Nxc6 bxc6 Bxc6+, winning a pawn and an exchange. With 1.4 million Lichess games across all rating levels, it is a specialized opening choice.
