White normally continues 2.exd5 when Black has two major continuations: 2...Qxd5 and 2...Nf6 (Marshall Gambit

). The rare move 2...c6 was played successfully by Joseph Blackburne on at least one occasion, but is thought to be unsound (after 3. dxc6), and is almost never seen in master-level play.

2... Qxd5

After 2...Qxd5, the most commonly played move is 3.Nc3 because it attacks the queen
Queen (chess)

–Kotrc Variation), one idea being that after the natural interposition 4.Be2, Black plays 4...Qg6 attacking the g2 pawn. This system is generally regarded as a terrible line because Black hasn't developed anything but his queen while White develops all his pieces. David Letterman

, in which Letterman was checkmated in 23 moves.

Returning to the main line after 3.Nc3 Qa5, White can choose from multiple set-ups. A common line is 4.d4 c6 (or 4...e5) 5.Nf3 Nf6 6.Bc4 Bf5 (6...Bg4 is a different option) 7.Bd2 e6. White has a few options, such as the aggressive 8.Qe2, or the quiet 8.0-0. Black's pawn structure (pawns on e6 and c6) resemble a Caro-Kann Defence

The Caro-Kann Defence is a chess opening —a common defense against the King's Pawn Opening characterised by the moves:The usual continuation isfollowed by 3.Nc3 , 3.Nd2 , 3.exd5 , or 3.e5 . The classical variation has gained much popularity...

 structure, therefore many Caro–Kann players wishing to expand their repertoire have adopted this form of the Scandinavian.

Another set-up after 3...Qa5 is to target the b7 pawn by fianchetto

ing the bishop on the h1–a8 diagonal, instead placing it on the a2–g8 diagonal, by 4.g3 Nf6 5.Bg2 c6 6.Nf3 followed by 0-0, Rb1, and then exploiting the b7 pawn by b4–b5.

A more speculative approach against 3...Qa5 is the gambit 4.b4?! If Black plays correctly, White should have no compensation for the sacrificed pawn, but it can be difficult to prove this over the board.

Alternatives to 3.Nc3 include 3.d4, which can transpose into a variation of the Nimzowitsch Defense after 3...Nc6 (1.e4 Nc6 2.d4 d5 3.exd5 Qxd5), or Black can play 3...e5, as well. After 3...Nc6 4.Nf3 Bg4 5.Be2 0-0-0 Black has better development to compensate for White's center after a future c4. Black may also respond to 3.d4 with 3...e5. After the usual 4.dxe5, Black most often plays the pawn sacrifice 4...Qxd1+ 5.Kxd1 Nc6. After White defends the pawn, Black follows up with ...Bg4+ and 0-0-0, e.g. 6.Bb5 Bg4+ 7.f3 0-0-0+ and Black has enough compensation for the pawn, because he is better developed and White's king is stuck in the center. Less popular is 4...Qxe5, since the queen has moved twice in the opening and is in the center of the board, where White can attack it with gain of time (Nf3). However, grandmasters such as Tiviakov have shown that it is not so easy to exploit the centralized queen.

Another common response after 2...Qxd5 is the noncommittal 3.Nf3. After 3...Bg4 4.Be2 Nc6, White can transpose to main lines with 5.d4, but has other options, such as 5.0-0.

The retreat with 3...Qd8 was depicted in Castellvi–Vinyoles, and may be the oldest of all Scandinavian lines. Prior to the 20th century, it was often considered the main line, and was characterized as "best" by Howard Staunton
Howard Staunton
Howard Staunton was an English chess master who is generally regarded as having been the world's strongest player from 1843 to 1851, largely as a result of his 1843 victory over Saint-Amant. He promoted a chess set of clearly distinguishable pieces of standardised shape—the Staunton pattern—that...

 in his Chess-Player's Handbook, but was gradually superseded by 3...Qa5. In the 1960s, 3...Qd8 experienced something of a revival after the move was played in a game by Bronstein against GM Andrija Fuderer

 in 1959, though Bronstein ultimately lost the game. Bronstein's game featured the older line 4. d4 Nf6, while other grandmasters explored fianchetto systems with 4. d4 g6 and a later Ng8–h6.

However, the line's reputation suffered after a string of defeats, including two well-known miniatures won by Bobby Fischer

) and William Addison in 1970. The variation with 4...g6 "has been under a cloud ever since [Fischer's] crushing win", but the 3...Qd8 variation as a whole remains playable, though it is now considered somewhat passive.

The move 3...Qd6 offers another way to play against 3.Nc3, and it has been growing in popularity in recent years. At first sight the move may look dubious, exposing the queen to a later Nb5 or Bf4, and for many years it was poorly regarded for this reason. However, numerous grandmaster games have since shown 3...Qd6 to be quite playable, and it has been played many times in high-level chess since the mid-1990s. White players against this line have found an effective setup with d4, Nf3, g3, Bg2, 0-0, and a future Ne5 with a strong, active position.

2... Nf6

The other main branch of the Scandinavian Defense is 2...Nf6, sometimes known as the Marshall Gambit after U.S. Chess Champion Frank Marshall, who played the line. The idea is to delay capturing the d5 pawn for another move, avoiding the loss of time that Black incurs in the ...Qxd5 lines after 3.Nc3. Now White has several possibilities:

The Modern Variation is 3.d4. Grandmaster John Emms calls this the main line of the 2...Nf6 variations, saying that "3.d4 is the common choice for White...and it is easy to see why it is so popular." The idea behind the Modern Variation is to give back the pawn in order to achieve quick development. 3...Nxd5 is the most obvious reply. Black wins back the pawn, but White can gain some time by attacking the Knight. White usually responds 4.c4, when the knight must move. The most common choices are 4...Nb6, named by Ron Harman and Shaun Taulbut as the most active option, and 4...Nf6, which Emms calls "slightly unusual, but certainly possible." A third alternative is the tricky Kiel Variation (4...Nb4?!), described by Harman and Taulbut as "a speculative try". Black is hoping for 5.Qa4+ N8c6 6.d5? b5! with a good game. However, White gets a large advantage after 5.a3 N4c6 6.d5 Ne5 7.Nf3 (or 7.f4 Ng6 8.Bd3 e5 9.Qe2) or 5.Qa4+ N8c6 6.a3!, so the Kiel Variation is seldom seen in practice. White may also play 4.Nf3 Bg4 5.c4. Now 5...Nb6 6.c5!? is a sharp line; Black should respond 6...N6d7!, rather than 6...Nd5? 7.Qb3, when Black resigned after 7...b6? 8.Ne5! in Timman
Jan Timman
Jan Timman is a Dutch chess Grandmaster who was one of the world's leading players from the late 1970s to the early 1990s. At the peak of his career he was considered to be the best non-Soviet player and was known as "The Best of the West"...

–Bakkali, Nice Olympiad 1974, and 7...Bxf3 8.Qxb7! Ne3 9.Qxf3 Nc2+ 10.Kd1 Nxa1 11.Qxa8 also wins for White.

An alternative to 3...Nxd5 is 3...Bg4!?, the sharp Portuguese Variation or Jadoul Variation. In this line, Black gives up the d-pawn in order to achieve rapid development and piece activity; the resulting play is often similar to the Icelandic Gambit. The normal continuation is 4.f3 Bf5 5.Bb5+ Nbd7 6.c4. Occasionally seen is 3...g6, the Richter Variation, which was played on occasion by Karl Richter
Karl Richter
Karl Richter was a German conductor, organist, and harpsichordist.

 in the 1930s.

Another common response is 3.c4, with which White attempts to retain the extra pawn, at the cost of the inactivity of the light-square bishop. Now Black can play 3...c6, the Scandinavian Gambit, which is the most common move. The line 4.dxc6? Nxc6, described by Emms as "a miserly pawn grab", gives Black too much central control and development. Most common after 3...c6 is 4. d4 cxd5, transposing to the Panov–Botvinnik Attack of the Caro-Kann Defence
Caro-Kann Defence
The Caro-Kann Defence is a chess opening —a common defense against the King's Pawn Opening characterised by the moves:The usual continuation isfollowed by 3.Nc3 , 3.Nd2 , 3.exd5 , or 3.e5 . The classical variation has gained much popularity...

. 3...e6!? is the sharp Icelandic Gambit or Palme Gambit, invented by Icelandic masters who looked for an alternative to the more common 3...c6. Black sacrifices a pawn to achieve rapid development. The most critical line in this double-edged variation is thought to be 4.dxe6 Bxe6 5.Nf3.

A third major alternative is 3.Bb5+. The most popular reply is 3...Bd7, though the rarer 3...Nbd7 is gaining more attention recently. After 3.Bb5+ Bd7, White has several options. The most obvious is 4.Bxd7+, after which White can play to keep the extra pawn with 4...Qxd7 5. c4. The historical main line is 4.Bc4, which can lead to very sharp play after 4...Bg4 5.f3 Bf5 6.Nc3, or 4...b5 5.Bb3 a5. Finally, 4.Be2 has recently become more popular, attempting to exploit the misplaced Bishop on d7 after 4...Nxd5.

White's 3.Nf3 is a flexible move that, depending on Black's reply, can transpose into lines with ...Nxd5 or ...Qxd5.

White's 3.Nc3 transposes into a line of Alekhine's Defence
Alekhine's Defence
Alekhine's Defence is a hypermodern chess opening that begins with the moves:Black tempts White's pawns forward to form a broad pawn centre, with plans to undermine and attack the White structure later in the spirit of hypermodern defence. White's imposing mass of pawns in the centre often includes...

, normally seen after 1.e4 Nf6 2.Nc3 d5 3.exd5, and generally thought to be equal. After 3...Nxd5 4.Bc4, the most common reply is 4...Nb6, although 4...Nxc3, 4...c6, and 4...e6 are also viable continuations.

Alternatives to 2. exd5

There are several ways for White to avoid the main lines of the Scandinavian Defense. One option is to defer or avoid the exchange of e-pawn for d-pawn. This is most often done by 2.Nc3, which transposes into the Dunst Opening
Dunst Opening
The Dunst Opening is a chess opening where White opens with the move:This fairly uncommon opening may have more names than any other: it is also called the Heinrichsen Opening, Baltic Opening, van Geet's Opening, Sleipnir Opening, Kotrč's Opening, Meštrović Opening, Romanian Opening, Queen's...

 after 2...d4 or 2...dxe4. If instead 2. e5?! is played, Black can get play 2...c5, develop the Queen's bishop, and play e6, reaching a favorable French Defense setup, since here unlike in the standard French Black's light-squared bishop is not shut in on c8. This line can also be compared to the Caro–Kann variation 1.e4 c6 2.d4 d5 3.e5 c5!?; since in the Scandinavian line Black has played c5 in one rather than two moves, he has a comfortable position.
White can also gambit the e-pawn, most frequently by 2. d4, transposing into the dubious Blackmar-Diemer Gambit
Blackmar-Diemer Gambit
The Blackmar–Diemer Gambit is a chess opening characterized by the moves:- History :The Blackmar–Diemer Gambit arose as a development of the earlier Blackmar Gambit, named after Armand Blackmar, a relatively little-known New Orleans player of the late 19th century who popularized its...

. Other lines are possible, but are seldom seen, and generally considered highly dubious; among these are 2. Nf3?! (Tennison's Gambit), 2. g4?! (the Zilbermints Gambit), and 2.d3 dxe4 3.Nc3. Other second moves for White are very rare.

In general, none of these sidelines are believed to offer White more than equality, and the overwhelming majority of masters opt for 2.exd5 when facing the Scandinavian. The Scandinavian is thus arguably Black's most "forcing" defense to 1.e4, restricting White to a relatively small number of options. This has helped to make the Scandinavian Defense fairly popular among club-level players, though it is rare at the Grandmaster level.
