Ruy Lopez

The slow, permanent pressure of the b5 bishop — the toughest test of 1.e4 e5

7 Chapters · 29 exercises

Origin

The name comes from the Spanish priest Ruy López de Segura, who analysed 3.Bb5 in his 1561 book. It only became a main weapon in the 19th century, with Steinitz and above all Morphy and Tarrasch shaping the modern lines. In the 20th century it became the central battleground of 1.e4 e5: Capablanca, Fischer, Karpov and Kasparov built entire careers on it, from both sides.

Why it works

After 1.e4 e5 2.Nf3 Nc6 3.Bb5, White's bishop eyes the c6 knight, the natural defender of Black's e5 pawn. The threat isn't immediate — 4.Bxc6 dxc6 5.Nxe5 gives the pawn back after 5...Qd4 — but it is pressure that never goes away and shapes every black move. White plays a4/h3, retreats the bishop via a4-b3-c2, and runs the classic Nb1-d2-f1-g3 manoeuvre to pile pieces up on the kingside, while d2-d4 settles the centre at a moment of White's choosing. It rewards structural understanding rather than tricks: learning the Ruy Lopez means learning positional chess.

In its favour

  • +The pressure on c6 and on the e5 pawn is permanent and costs White no concessions.
  • +The centre stays flexible: White chooses when to play d2-d4 or keep the tension with c3 and d3.
  • +It offers clear long-term plans, such as the Nb1-d2-f1-g3 manoeuvre and the kingside attack.
  • +It has huge educational value: it teaches structures, manoeuvres and elite-level piece play.

The price

  • −The theoretical load is enormous — Marshall, Breyer, Zaitsev and Berlin are each full bodies of theory.
  • −Black has many sound defences, and you need a ready answer to the Berlin, Open, Schliemann and Arkhangelsk.
  • −The closed positions demand patience: anyone wanting quick decisions will chafe at ten-move manoeuvres.
  • −The Exchange Variation simplifies early and offers little practical edge against accurate defence.

Chapters

  1. 1The First Three Moves and What the b5 Bishop DoesHere you see why 3.Bb5 attacks the c6 knight, the defender of Black's e5 pawn, and why that pressure is slow rather than immediate. It is the required starting point before any variation.0/3
  2. 2The Exchange Variation and Its Delayed VersionBxc6 dxc6 hands Black the bishop pair but damages Black's queenside pawn structure. You learn White's plan of trading pieces and steering for the endgame, plus the delayed version with 4.Ba4 a6 5.Bxc6.0/3
  3. 3Third-Move Defences: Berlin, Classical, Steinitz, Cozio and BirdNot every game goes through 3...a6. This chapter covers the alternatives — 3...Nf6, 3...Bc5, 3...d6, 3...Nge7 and 3...Nd4 — and what White does against each.0/6
  4. 4The Morphy Defence and the Closed Ruy Lopez3...a6 4.Ba4 Nf6 5.O-O Be7 is the main road: the bishop retreats via a4-b3-c2, White plays c3, h3 and d4, and the pieces gather with Nb1-d2-f1-g3. This is the positional heart of the opening.0/4
  5. 5Open Defence, Schliemann and ArkhangelskBlack can refuse the manoeuvring game: 5...Nxe4 opens the centre at once, 3...f5 is an aggressive gambit, and 5...b5 6.Bb3 Bb7 puts the bishop on the long diagonal. These are lines of concrete play and calculation.0/5
  6. 6The Marshall Attack and How to Dodge ItWith 8...d5 Black sacrifices a pawn for lasting kingside initiative — theory memorised to move 25. You see both sides plus the practical alternative 8.a4, which cuts the Marshall off before it starts.0/4
  7. 7The Great Closed Systems: Chigorin, Breyer, Zaitsev and SmyslovThe most demanding material in the course: 9...Na5, 9...Nb8, 9...Bb7 and 9...h6, each with its own piece regrouping and counterplay plan. These are long manoeuvring games won by whoever understands the structure better.0/4
