This opening is not about grabbing space and sitting back. Your queen has already moved, so your compensation has to come from speed, piece activity, and good coordination. White will usually try to use the lead in development, so your job is to meet that pressure without wasting time.
The best practical habit here is to finish development with purpose. Keep your pieces active, look for easy squares for them, and do not let White’s lead in space turn into a direct attack. The position is playable, but it rewards accuracy.
What the engine prefers here
Stockfish rates this +0.63, a small edge for White. That means you are slightly worse here.
The engine’s best move is Nf3, continuing Nf3 Nf6 d4 Bf5. The message is clear: White’s most natural development is also the most testing. If you know how to answer that kind of setup, you will feel much more comfortable meeting the main line over the board.
Which replies White chooses most often
This exact position has been reached in 17,416,927 games, so you are not learning a side road. You are practising a very common tabiya.
The most-played continuations are:
- Nf3 — 6,592,520 games, White scores 47.2%
- d4 — 5,118,861 games, White scores 48.9%
- d3 — 1,823,545 games, White scores 47.2%

- b4 — 527,782 games, White scores 56.1%
- a3 — 351,517 games, White scores 46.9%
That spread tells you White has several normal developing ideas, but none of them is a free ride. Your task in the drill is to get comfortable meeting the ones that appear again and again.
The one mistake to watch for
One move stands out as a known mistake: b4. It is an inaccuracy and loses about 0.8 pawns; better was Nf3.
If White pushes the b-pawn too early, do not panic. Stay calm, keep developing, and remember that premature wing play can make White’s position easier to handle than it first looks. The lesson here is not to chase the pawn with your queen, but to punish the loss of time by completing your own development.

Frequently asked questions
Is the Scandinavian Defense: Main Line good for Black?
It is playable, but this exact position is slightly better for White. Stockfish gives +0.63, so you should not expect an easy equal game just by reaching it. The opening is still very practical if you know the main ideas and develop efficiently.
What is the main plan for Black here?
Develop quickly and keep your pieces active. Since your queen has already moved, you need smooth coordination rather than time-wasting pawn moves. The engine’s best continuation shows that White’s natural development is the move you must be ready for.
Which White move should I expect most often?
Nf3 is the most common continuation, with 6,592,520 games in the database. d4 is also very popular, and other normal developing moves like d3 and Bc4 appear often too. It is worth drilling the position until these replies feel familiar.
Is b4 a serious try for White?
It is the one listed mistake in this position. The database marks it as an inaccuracy, and it loses about 0.8 pawns; better was Nf3. If you see it, treat it as a chance to seize the initiative through sound development.
