Ruy Lopez: Closed, Bogoljubow Variation

Definition

The Bogoljubow Variation is an historical branch of the Closed Ruy Lopez (Spanish Opening) in which Black reinforces the e5–point with …d6 and only then completes development with …O-O. The ECO code most commonly associated with the line is C91. A typical starting position of the variation arises after:

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7
6. Re1 b5 7. Bb3 d6 8. c3 O-O 9. h3

Here Black’s set-up (…d6 before …O-O) and the intention to manoeuvre the queen’s knight via b8–d7–f8–g6 or to strike in the centre with …c5 / …d5 were championed by the Ukrainian-born grandmaster Efim Bogoljubow, World Championship challenger in 1929 and 1934.

Typical Move Order

e4 e5
Nf3 Nc6
Bb5 a6
Ba4 Nf6
O-O Be7
Re1 b5
Bb3 d6 (↞ distinguishing move)
c3 O-O
h3 … and the Bogoljubow tabiya is reached.

Strategic Themes

Flexible central play. By holding back …d5 for the moment, Black keeps the centre closed and can choose between …c5, …Na5–c4 or …d5 depending on White’s set-up.
Knight manoeuvres. A trademark idea is …Nb8–d7–f8–g6, putting pressure on e5 and preparing …f5 in some lines. This slow regrouping reflects classic Spanish manoeuvring play.
Minor-piece tension on the a2–g8 diagonal. Black’s dark-squared bishop may come to e6, d7 or even g4, while White usually tries to maintain the powerful Ba4/Bb3 along the long diagonal in connection with a later d2–d4 break.
Plans for White. The standard approach is d2–d4 (often preceded by a4 or h3), eventually building a large central pawn-phalanx. Other ideas include the slow manoeuvre Nb1–d2 -f1-g3 and the dangerous pawn thrust a2–a4 undermining Black’s queenside.

Historical Background

Efim Bogoljubow began experimenting with this move order in the 1920s, seeking a middlegame structure he understood deeply against the ever-popular Ruy Lopez. Although later eclipsed by the Chigorin (9…Na5), Breyer (9…Nb8) and the dynamic Marshall Attack, the Bogoljubow line laid the groundwork for many key manoeuvres that still appear in modern Spanish theory.

Famous Games

Alekhine – Bogoljubow, World Championship (Game 15), Wiesbaden 1929. Bogoljubow used his pet variation to reach an equal, manoeuvring middlegame, though Alekhine’s end-game technique eventually prevailed.
Smyslov – Tal, USSR Championship 1957. Tal briefly flirted with the Bogoljubow move order before steering into a Chigorin-style structure. It shows how easily the lines can transpose.

Interesting Facts & Anecdotes

Efim Bogoljubow reportedly recommended the line to his students with the words: “First keep everything solid – then Schlagen furchtbar (strike terribly)!”
Because Black can still choose between …Na5 and …Nb8 in many positions, modern databases often lump Bogoljubow games together with Chigorin or Breyer material – a headache for opening statisticians.
The variation is occasionally revived as a move-order trick to sidestep the ferocious Marshall Attack (where Black plays an early …d5 sacrifice). With 7…d6 Black says “no Marshall today.”
Several correspondence specialists consider the Bogoljubow set-up a robust drawing weapon against the Ruy Lopez, citing its resilient pawn structure and reduced theoretical forcing lines compared to the Marshall or Zaitsev.

Practical Tips

Do not forget the prophylactic …h6; allowing Bg5 can severely cramp Black’s position.
After …Nb8-d7-f8-g6, watch for the thematic pawn break …d5. If timed correctly it can fully equalise or even seize the initiative.
From the White side, the move a2-a4 is a useful lever: if Black reacts with …bxa4 the a-file opens against Black’s weak a6-pawn; if Black pushes …b4 the b4-pawn can become a hook for c2-c3.
