QGD: 4.Bg5 Be7 5.e3 Nbd7
QGD: 4.Bg5 Be7 5.e3 Nbd7
Definition
The sequence 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Be7 5.e3 Nbd7 is a main-line position in the Queen’s Gambit Declined (QGD). It forms part of the so-called QGD Orthodox Defence, distinguished by the early development of Black’s queen’s knight to d7 while the g5–pin remains in place. The position can occur via many transpositions, but the essential hallmarks are:
- White’s dark-squared bishop is actively posted on g5, pinning the f6-knight.
- Black has replied symmetrically with …Be7 and then …Nbd7 instead of immediately castling or playing the sharper …h6 (Lasker) or …b6 (Tartakower).
Move Order and Usage
The critical branch is reached after:
- 1.d4 d5
- 2.c4 e6 – The Queen’s Gambit Declined setup.
- 3.Nc3 Nf6 – Developing the king’s knight while watching e4.
- 4.Bg5 – The most classical “pin” move, attacking the f6-knight and indirectly the d5-pawn.
- …Be7 – A flexible answer. Black quietly breaks the pin and prepares to castle.
- 5.e3 – White shores up the d4-pawn, opens lines for the c1-bishop and eyes future central play.
- …Nbd7 – The key defining move of this line, over-protecting f6 and d5, supporting …c5 or …e5 in the future, and keeping the option of recapturing on f6 with the knight.
Tournament players adopt this line when they desire rock-solid equality, avoiding the sharper complications of the Lasker Defence (…h6), the Tartakower–Makogonov–Bondarevsky (…b6) system, or the Cambridge Springs (…Qa5). It is therefore a favourite of players with a positional style who nevertheless want a fully sound opening.
Strategic Themes
- Central Tension: Both sides keep the pawn duo d4–c4 vs. d5–e6 intact for several moves. Deciding when to capture on d5 / c4, or to advance e3-e4 / …c5, is the essence of the variation.
- Bishop Pair Considerations: White often exchanges Bg5xf6, doubling Black’s f-pawns, in return for c1-bishop activity. Black, thanks to …Nbd7, can recapture with the knight instead to maintain structure.
- Minor-Piece Manoeuvres: Typical routes include Nf3–d2–b3 or Ne5; for Black the b6-knight can re-route to f8–g6 or b6 after …b6.
- Queenside Majority: After the common pawn exchange cxd5 exd5, White has a 4-vs-3 majority on the queenside, which can become a long-term end-game asset (Carlsbad structure).
- Breaks: • White: e3-e4, sometimes c4-c5. • Black: …c5, …e5, or the freeing …h6 & …Ne4.
Typical Plans
- For White
- Castle short, play Qc2 or Rc1 and aim for a minority attack with b4-b5.
- Exchange on f6 when it damages Black’s pawn structure or forces concessions.
- Prepare e3-e4 with Nf3–d2 and f2-f3, seizing space in the centre.
- For Black
- Maintain the tension, complete development with …0-0, …c6 or …c5.
- If doubled f-pawns are accepted, use …f7-f5 to gain kingside space.
- Adopt the classical “Capablanca plan”: …Re8, …Nf8, …Ng6, followed by …e5.
Historical Significance
The Orthodox Defence with 5…Nbd7 has been a cornerstone of grand-master practice for over a century. Legendary world champions Emanuel Lasker and José Raúl Capablanca defended it with great success, showcasing its solidity. In modern times, elite players such as Magnus Carlsen, Viswanathan Anand, and Sergey Karjakin have revived it at the highest level, valuing its reliability in match play.

Interesting Facts & Anecdotes
- When Capablanca scored his famous undefeated 1916-1924 streak, this very structure featured in several of his black games; he once joked that “with …Nbd7 in place, one could almost play on autopilot.”
- The line is sometimes dubbed the “Berlin Wall of the QGD” for its resilience: like the Berlin Defence to 1.e4, it concedes little and invites a long manoeuvring battle.
- Computers initially underestimated Black’s chances here; early engines favored White by +0.30. Modern neural-net evaluations (Leela, 2020+) hover around 0.00, validating its sturdiness.
When to Choose This Line
Play 5…Nbd7 if you:
- Enjoy solid, strategic positions with minimal early tactics.
- Are willing to defend slightly passive positions in order to reach an equal end-game.
- Want a mainline opening that has stood the test of time at every rating level.
