Scandinavian Defense
Initial Moves: 1.e4 d5
Strategic Summary & Main Idea
The Scandinavian Defence trades the central pawn on move one and solves, at a stroke, the problem of anyone facing 1.e4 who does not want to memorise ten systems: after 1...d5 there is one structure to learn. The price shows in the measurement: the position measures +0.64, and the most popular version, with 3...Qa5, reaches +0.78. The queen comes out early, is attacked with gain of time, and White develops for free. What the defence gives back is predictability — and one line the engine approves of: the Icelandic Gambit, with 3.c4 c6, measures −0.62 in Black's favour.
The pawn structure this opening produces
After 1.e4 d5 2.exd5 the structure is asymmetric in a way that shapes everything to come: White has pawns on d2 and f2, Black an extra queenside pawn and nothing in the centre until d5 is recovered. Recovering with the queen leaves a Caro-Kann without the c6 pawn — solid, slightly passive, and with the c8 bishop free for f5 or g4, which is the defence's only real positional asset. Recovering with the knight, in the Marshall Variation, invites c4 to kick the piece, costing more time than the queen would have. And recovering nothing at all, in the Icelandic Gambit, means Black plays ...c6 and gives the pawn back for development — the structure opens, White's queen stays at home, and the evaluation flips. What every version shares is the d4 square and the d-file: White builds a pawn on d4, and Black needs ...c6 and ...Bf5 before that centre grows. Anyone who plays the Scandinavian and forgets ...c6 ends up without a retreat square for the queen and without the good bishop at the same time.
Typical Plans for White
- Win the tempo back with Nc3 hitting the queen and finish developing before forming any plan
- Build d4 and Nf3 and play against Black's lack of space, the opening's permanent asset
- Against 2...Nf6, push c4 and kick the knight: the Marshall Variation measures +0.88, the second highest here
- Hold the d5 pawn with c4 only when Black does not have ...c6 ready
- Do not take everything in the Icelandic Gambit: give the pawn back on time, since the greedy line measures −0.62
Typical Plans for Black
- Recapture with the queen and retreat it to a square where it will not be hit again
- Play ...c6 and ...Bf5 before ...e6 — the only way the structure works
- Choose 3...Qd6, which sidesteps Bd2, and live with the +1.04 evaluation
- Try the Icelandic Gambit with 2...Nf6 3.c4 c6, the only line measured here in Black's favour
- Do not push ...e5 with the queen on a5 — the centre opens against your own king

Frequently asked questions
Is the Scandinavian a bad defence?
It measures +0.64 after 1...d5, and +0.78 in the most played line. That does not make it unplayable — half a pawn is perfectly defensible over the board — but it is the honest price of an early queen sortie. What it buys is one structure to learn, and for a light studier that trade can be worth it.
Where should the queen go after ...Qxd5?
The three squares measured here sit close together: a5 at +0.78, d8 at +0.73 and d6 at +1.04. The cheapest version in this entry is the passive one, ...Qd8 followed by ...e6 and ...Be7, at +0.56. In other words the square matters less than the setup that follows it — and the setup that concedes least is the least ambitious one.
Does the Icelandic Gambit work?
By the measurement, yes, and it is the only line in this entry in Black's favour: after 2...Nf6 3.c4 c6 4.dxc6 Nxc6 the position measures −0.62. The pawn buys two tempi of development and a white queen still sitting at home. The practical conclusion is direct: White should not take everything — giving the pawn back on time is what keeps the edge.

Common Mistakes & Where Most Amateurs Go Wrong
- 01 Pinning with ...Bg4 and retreating to h5 after h3. The g4 push wins the bishop's square with tempo and White attacks with the king still in the centre at no risk: the position rises from +0.78 to +1.33. The line:
1.e4 d5 2.exd5 Qxd5 3.Nc3 Qa5 4.d4 Nf6 5.Nf3 Bg4 6.h3 Bh5 7.g4 Bg6 8.Ne5 e6 9.h4+1.33 - 02 Breaking with ...e5 while the queen is still on a5. The e-file opens with Black's king on it, and after 7...Qe7 White castles with every piece pointing at the centre: +1.53. The line:
1.e4 d5 2.exd5 Qxd5 3.Nc3 Qa5 4.d4 e5 5.dxe5 Qxe5+ 6.Be2 Bb4 7.Nf3 Qe7 8.O-O+1.53
