QGD: 4.Bg5 Be7 5.e3 h6 – Orthodox Defence
QGD: 4.Bg5 Be7 5.e3 h6
Definition
The sequence 1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Bg5 Be7 5. e3 h6 is a tabiya of the Queen’s Gambit Declined (QGD), specifically the Orthodox Defence with an early …h6. It arises after White pins the f6-knight with 4.Bg5 and Black unpins by 4…Be7, then tries to question the bishop with 5…h6.
Move Order & Position
After the sixth move (5…h6) the position contains the following key features:
- Pawns: d4–d5 tension still intact; the e-pawns are unmoved.
- Pieces: White’s dark-squared bishop sits on g5; Black’s king bishop has retreated to e7; knights on c3 and f6.
- Castling: Neither side has committed the king, but both are only one move away from castling kingside.

Strategic Ideas
- Black’s Aim with …h6
- Force the dark-squared bishop to clarify its intentions (retreat, exchange, or pin maintenance on h4).
- Prevent potential tactical ideas based on Bxf6 followed by Qxd5 when the d-pawn is loose.
- Gain luft for the king after castling.
- Typical White Reactions
- 6.Bh4 – keeps the pin; can transpose to the Main Orthodox.
- 6.Bxf6 – exchange on f6 leading to doubled f-pawns; resembles the Exchange Variation ideas.
- 6.Bf4 or 6.Bg3 – less common, aiming for flexibility.
- The Centre: Because neither side has yet committed to …c5 or …dxc4, central tension remains, and both players can choose from a variety of pawn-breaks (e4, cxd5, or …c5).
Historical Significance
The Orthodox Defence (4…Be7) was championed in the late 19th century by Emanuel Lasker, who proved its resilience in his World Championship matches. While Lasker often delayed …h6, the move became popular in the 20th century as players like Paul Keres and Vasily Smyslov showed that it solves many tactical issues without losing time.
In modern practice, top grandmasters—including Garry Kasparov and Vladimir Kramnik—have used 5…h6 as a flexible waiting device, sometimes provoking White into revealing his hand too soon.
Usage in Opening Preparation
For Black, choosing 5…h6 is a stylistic decision:
- Players who like clear structures and the possibility of …dxc4 combined with …b5 often pick this move.
- It sidesteps the sharper Cambridge-Springs (4…Nbd7 5.e3 c6 6.Nf3 Qa5) or the Tartakower (…b6) lines.
For White, preparation splits into:
- 6.Bh4 set-ups with Nf3, Rc1, and possibly cxd5 followed by Ne5.
- 6.Bxf6 plans aiming at minority attack structures (b2-b4-b5) once Black recaptures with the queen.
Illustrative Games
-
Smyslov – Botvinnik, World Championship 1954 (Game 12)
White played 6.Bh4 and later adopted the classical buildup with Rc1 and Qc2. Botvinnik’s precise …c5 break equalised, showing the robustness of Black’s scheme. -
Kramnik – Topalov, Dortmund 2000
Kramnik simplified with 6.Bxf6 and steered the game into an endgame where the doubled f-pawns gave him a small but lasting edge, sufficient for victory.
Typical Plans & Tactics
- For White
- Minority attack: after cxd5 exd5, advance b2-b4-b5 to create queenside weaknesses.
- Central expansion: prepare e2-e4 once the tension on d5 is resolved.
- Piece play: place a knight on e5 against Black’s kingside.
- For Black
- …dxc4 followed by …c5 or …b5, freeing the position and activating the light-squared bishop.
- …Ne4 (Lasker idea) to trade minor pieces and head for an endgame.
- …c5 directly, challenging the centre in classical QGD fashion.
Interesting Facts & Anecdotes
- The move 5…h6 is sometimes nicknamed the “Nudge”, because it politely asks the g5-bishop about its future residence without committing the rest of Black’s forces.
- In correspondence chess, early …h6 scored so well for Black that several White repertoires recommend avoiding 4.Bg5 altogether, favouring 4.Nf3 or 4.cxd5.
- Karpov used the line with Black in his youth but later switched to the Tartakower, stating in an interview that “…h6 is good, but I prefer …b6 because it gives me more dynamic chances.”
Conclusion
The sequence 4.Bg5 Be7 5.e3 h6 is a solid, strategically rich branch of the Queen’s Gambit Declined. Both sides enjoy a wealth of plans; understanding the subtleties behind the modest-looking pawn push to h6 can greatly enhance one’s QGD expertise.
