The Scandinavian Defense (the Center Counter) — its main lines, the plans for both sides, and how to tell whether it fits your style.

TL;DR The Scandinavian Defense (ECO B01) begins with 1.e4 d5. Played in tournament chess for more than 500 years, it is a defense for Black against 1.e4. This guide walks through its main variations, the typical plans and pawn structures for both sides, its famous practitioners, and who should add it to their repertoire — then shows how to check whether it actually works in your own games.

Starting position and moves

The Scandinavian Defense (also known as the Center Counter) is a defense for Black, classified under ECO codes B01. It begins with:

The idea behind the Scandinavian Defense

Black challenges the e4-pawn immediately with 1...d5. After 2.exd5 Qxd5, the queen comes out early — normally a beginner's mistake — but here it is sound because White cannot trap or profitably attack it. The Scandinavian is a low-theory, easy-to-learn defence that reaches solid, recognisable structures.

Main lines and key variations

VariationMoves
Main Line (3...Qa5)1.e4 d5 2.exd5 Qxd5 3.Nc3 Qa5
Modern (3...Qd6)1.e4 d5 2.exd5 Qxd5 3.Nc3 Qd6
Portuguese Gambit1.e4 d5 2.exd5 Nf6

Main Line (3...Qa5): The queen retreats to a5, out of the way of tempo-gaining moves, and Black builds with ...Nf6, ...c6, ...Bf5.

Modern (3...Qd6): A flexible, popular modern retreat that keeps the queen active and eyes the kingside.

Portuguese Gambit: 2...Nf6 offers a gambit to recapture actively with pieces rather than the queen — sharper and more ambitious.

Plans for both sides

White's plans

Black's plans

Typical pawn structure

Black gives up the fight for the extra centre pawn but reaches a very sound, easy-to-play structure similar to the Caro-Kann. The early queen sortie costs a little time but no material or structure.

Famous practitioners

The Scandinavian Defense has been championed by Bent Larsen, David Smerdon, Magnus Carlsen (occasionally). Carlsen's surprise Scandinavians: Magnus Carlsen has used the Scandinavian as a practical surprise weapon in classical and rapid play.

Strengths and weaknesses

Strengths. Very low theory — great time investment; Forces the game onto your own terms after 1.e4; Solid and hard to refute.
Weaknesses. The early queen move loses a little time; Slightly passive if Black plays inaccurately.

Who should play the Scandinavian Defense?

Frequently Asked Questions

Is it bad to bring the queen out early in the Scandinavian?

Normally moving the queen out early is a mistake, but the Scandinavian is the well-known exception. After 3.Nc3 the queen simply steps back to a5, d6, or d8, and White cannot gain a lasting attack against it — Black loses only a tempo or two, which the solid structure fully compensates.

Is the Scandinavian Defense good for beginners?

It is excellent for beginners and busy players because it has far less theory than most 1.e4 defences and reaches the same position no matter what White does. You learn one clean set-up (…Nf6, …c6, …Bf5, …e6) and can play it against almost anyone.

What is the Portuguese Gambit?

After 1.e4 d5 2.exd5 Nf6, Black declines to recapture immediately and instead develops with tempo, often sacrificing the pawn for fast piece play with ...Bg4. It is sharper and more ambitious than the classical 2...Qxd5 lines.
