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. Much of the play and counterplay in the beginning of the Spanish opening revolves around White creating threats to play Nxe5, Black defending against them, and White finding new ways to reinvigorate the threat. By defending e5 with a pawn, 4...d6 defuses the threat for good. 4...d6 has the advantage of defending e5 and allowing Black's queen's bishop to develop, but closes off the diagonal Black opened for the king's bishop when they played 1...e5, and transforms White's bishop's latent pressure on their knight into a pin. The "modern Steinitz" or "deferred Steinitz" defence is a strict improvement over Steinitz's original suggestion or the "Old Steinitz", 3...d6, because the inclusion of 3...a6 4. Ba4 means Black can cut off that pin whenever they wish with ...b5. The difference can be seen if White tries 5. d4?! . 5. d4?! on the face of it seems reasonable, for the same reasons it is the critical move against the 3...d6 move order. Black has only one defender of e5 (...d6 added the pawn to the defence but remove the knight by pinning it). So, White hopes to win it by playing dxe5 dxe5 Nxe5. If this compels Black to take on d4 instead, White thinks, then 5...exd4? 6. Nxd4 threatens Nxc6 bxc6 Bxc6+ to win a pawn and an exchange.
