The Orthodox Defense is all about patience. White's bishop on f4 eyes the c7-pawn and supports the idea of an early e3, building a solid centre without committing to anything aggressive. Your job as Black is to finish development — castles short, get your light-squared bishop outside the pawn chain (usually to b7 or d6), and eventually chip away at White's centre with ...c5 or ...e5 breaks. The engine's top choice for White is 6.e3, which has been played in 17,206 games, and against that you should respond with 6...O-O. That simple move allows White to continue with ideas like c5 or Nh5, but you are not in any real danger. The small plus for White (+0.43) comes from a space advantage, not from any immediate threat. Stay calm, develop, and you are already on the right track.
The Most Popular Continuation: 6.e3
White's most common move by far is 6.e3 (17,206 games, White scoring 52.0%). After 6...O-O, the engine recommends White follow up with 7.c5 or 7.Nh5 — both tricky but manageable. Your plan is the same: finish kingside castling, then decide where to put the c8-bishop. Many club players rush to play ...b6 here, but watch out: if White pushes c5, you may want to prepare ...e5 or ...c6 first. If White plays 7.Nh5, they are threatening to exchange their knight for your excellent f6-knight, which also attacks the bishop on f4. You can simply retreat your king's knight to e8 or g4 — do not panic. The 52.0% White score here is the lowest among the main moves, which tells you that 6.e3 gives Black the best practical chances. Trust the statistics: this is where you want White to go.
Watch Out: The Sharp Nb5 Line
The engine's best move might actually surprise you: although e3 is most popular, the engine prefers Nb5 (2,619 games, White scores 59.8%). That 59.8% is a red flag — this line scores much better for White than e3, and it is also the suggested improvement over the inaccuracies h3 and cxd5. After 6.Nb5, White threatens Nxc7+ or ideas with a4 and the c5 square. Your best reply is ...O-O, keeping your king safe, and then you need to deal with the pressure on the c7-pawn and the d6-square. This is more forcing than the e3 line, so study the ideas: you may need to play ...a6 to ask the knight what it wants, or sometimes ...Bb4 to counter-attack. Do not fear it — just know that this is the critical test of your opening knowledge.
Two Inaccuracies You Can Exploit
The database flags two common White mistakes in this position. If your opponent plays 6.h3 (1,563 games, White scores 51.7%), the engine says it loses about half a pawn — White should have played 6.Nb5 instead. Use this: after 6.h3, you can develop with ...O-O and follow up with ...b6 or ...dxc4, because White's h3 is a wasted tempo that does nothing to control the centre. The other inaccuracy is 6.cxd5 (1,134 games, White scores 49.5% — the lowest White score of any main line!). That's right: when White captures on d5, Black scores over 50%! After 6.cxd5 exd5, Black has a symmetrical centre with easy development and no weaknesses. The 49.5% White score tells you this is a gift — take it. Develop, play ...c6, and enjoy equal play. If you see either h3 or cxd5 on the board, you have already outplayed your opponent in the opening.

Frequently asked questions
Is the QGD Orthodox Defense Bf4 a good opening for Black?
Yes, it is very solid. The statistics show Black scores 43.2% across nearly 25,000 games, and the engine evaluation of +0.43 for White means you are only slightly worse. With accurate play you can equalise in the middlegame. It is ideal for Black players who prefer strategic, patient chess over sharp tactics.
What is White's best move after 5.Bf4 Nbd7?
The engine recommends 6.e3, which is also the most-played move (17,206 games). However, 6.Nb5 scores better for White (59.8%) and is the engine's preferred alternative if White wants to push for an edge. As Black, you should be prepared for both.
Should Black capture on c4 in this line?
Not immediately. In the QGD Orthodox Defense, Black usually waits before taking on c4. The main ideas involve castling first and then deciding on ...dxc4 (often after ...b6 and ...Bb7). The position after 5.Bf4 Nbd7 is still fluid, and premature captures can give White a free tempo with e4.
Why is h3 a mistake for White here?
The engine flags 6.h3 as an inaccuracy, losing about half a pawn. It is a non-developing move that does nothing to fight for the centre or prevent Black's plans. White should have played 6.Nb5 instead. Against h3, Black can develop comfortably with ...O-O and later challenge the centre with ...c5 or ...e5.
