Ruy López
The Spanish Torture: a slow, positional squeeze that has been the acid test of 1.e4 e5 for over four centuries.
| # | White | Black |
|---|---|---|
| 1. | e4 | e5 |
| 2. | Nf3 | Nc6 |

White pressures c6 to loosen Black’s centre; Black gains queenside space with …b5 and heads for the Closed Ruy.
The idea
The Ruy López (or Spanish Opening) attacks the knight on c6 with 3.Bb5. That knight defends the e5-pawn, so by pressuring it White creates a subtle, lasting question mark over the centre of Black’s position. Rather than winning material outright, White accumulates tiny structural advantages, keeps the tension, and manoeuvres for the long game — which is why it has been nicknamed "the Spanish Torture."
Main line explained
After 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 (the Morphy Defence) White retreats with 4.Ba4, keeping the bishop’s pressure alive while sidestepping …b5 tricks for now. 4…Nf6 hits e4, 5.O-O tucks the king away and quietly offers the e4-pawn (it is poisoned by tactics), 5…Be7 develops solidly, and after 6.Re1 defending e4, Black gains queenside space with 6…b5, chasing the bishop to b3 and reaching the great Closed Ruy main lines.
Plans for both sides
White: White plays for a big, well-supported centre: c3 and d4 build the classic pawn duo, while the b3-bishop and a re-routed knight (Nbd2–f1–g3, the "Spanish knight tour") aim at the kingside. The bind on e5 and pressure down the e-file give White a durable, low-risk initiative.
Black: Black gets a rock-solid position with counterplay. The bishop on b3 can be neutralised with …Na5 or blunted with …d6 and …Nc6–a5; queenside space from …b5 and …c5 gives real space of its own, and the resilient centre means Black is rarely worse if the theory is known.
A common trap to avoid
Watch the Noah’s Ark Trap. If White grabs the centre carelessly with an early d4, Black can round up the b3/a4-bishop with a wall of queenside pawns: …b5, …Nxd4, …exd4, and then …c5–c4 slams the door, trapping the bishop behind Black’s own pawns. Time your d4 and keep an escape square for the light-squared bishop.
Who it suits
Patient, positionally-minded players who enjoy long strategic manoeuvring and want the most principled, deeply-respected answer to 1…e5. Expect to learn ideas, not just memorise moves.
In this line you play White. The board above shows the position reached after 6...b5.
