Alekhine Defense Scandinavian Variation

The Alekhine Defense Scandinavian Variation starts 1.e4 Nf6 2.Nc3 d5. Black avoids the usual 2.e5 main lines and asks White to choose between a clean 3.exd5 game and sharper 3.e5 systems.

Quick recommendation

Choose this line as Black if you want an independent answer to 2.Nc3 and are ready to study the 3.e5 branches. Choose it as White if you want to avoid normal Alekhine theory and steer Black into less familiar Scandinavian/French crossover positions.

  • Main starting point: 1.e4 Nf6 2.Nc3 d5.
  • Cleaner route: 3.exd5 Nxd5 4.Bc4.
  • Sharper route: 3.e5 with ...d4, ...Nfd7, or ...Ne4.
  • Replay focus: Hector-style pressure games show why 2...d5 needs preparation.

Key diagrams and practice positions

Each diagram uses a FEN calculated from the example sequence. Use the button under the sequence to play the exact position against the ChessWorld computer.

Scandinavian Variation starting point

White chooses between 3.exd5 and 3.e5. This is the independent Alekhine crossroads: Black challenges immediately with ...d5 instead of entering the normal 2.e5 chase.

Example sequence: 1.e4 Nf6 2.Nc3 d5

The 3.exd5 Nxd5 4.Bc4 test

White develops with tempo and asks Black where the knight belongs. ...Nb6 and ...Nxc3 are the clean equalising tries; ...e6 is solid but shuts in the light-squared bishop.

Example sequence: 1.e4 Nf6 2.Nc3 d5 3.exd5 Nxd5 4.Bc4

The calm ...Nb6 equaliser

Black keeps the knight pair and develops naturally. The position is roughly equal, but White can still aim for d4, Nf3 and fast castling.

Example sequence: 1.e4 Nf6 2.Nc3 d5 3.exd5 Nxd5 4.Bc4 Nb6 5.Bb3 Nc6

The Ove Ekebjaerg 4.g3 idea

White fianchettoes and accepts doubled c-pawns, but Black’s queen activity and ...Bd7-c6 plan are the reason this line is considered comfortable for Black.

Example sequence: 1.e4 Nf6 2.Nc3 d5 3.exd5 Nxd5 4.g3 Nxc3 5.bxc3 Qd5 6.Qf3 Qe6+ 7.Qe2 Qxe2+ 8.Nxe2 Bd7

The combative 3.e5 d4 branch

Black grabs space and challenges the knight before White has built the normal Alekhine centre. White must choose between retreating with Nce2 and the sharp exf6/dxc3 pawn race.

Example sequence: 1.e4 Nf6 2.Nc3 d5 3.e5 d4

The ...Nfd7 French-style transposition

This can transpose to a Steinitz French structure. White’s extra option is the sharper 4.e6 idea before Black settles the centre.

Example sequence: 1.e4 Nf6 2.Nc3 d5 3.e5 Nfd7 4.d4 e6

The provocative 3...Ne4 option

The knight jumps forward instead of retreating to d7 or allowing ...d4. White usually tests it with Nce2, Qf3 or Nxe4 ideas, so Black needs exact move-order knowledge.

Example sequence: 1.e4 Nf6 2.Nc3 d5 3.e5 Ne4

Hector-style pawn race after 3...d4

This is the sharpest structural idea from the 3.e5 d4 branch: both sides damage normal development, but White often gets quick castling and practical pressure.

Example sequence: 1.e4 Nf6 2.Nc3 d5 3.e5 d4 4.exf6 dxc3 5.fxg7 cxd2+ 6.Bxd2 Bxg7

Plans for White

  • Against 3...Nxd5: develop with Bc4, Nf3, d4 and castle quickly. Do not let Black’s knight retreats become free tempi.
  • Against the 4.g3 queen line: respect ...Qd5 and ...Qe6+. If queens come off, play for development and structural targets rather than a quick attack.
  • Against 3...d4: decide whether you want Nce2 solidity or the pawn-race with exf6 and fxg7.
  • Against 3...Nfd7: choose between French-style central play with d4 and the sharper e6 disruption.
  • Against 3...Ne4: challenge the knight with concrete moves. Do not drift into slow development while Black keeps the centre.

Plans for Black

  • After 3.exd5: recapture with ...Nxd5 and know your answer to 4.Bc4 before playing the line.
  • With ...Nb6: keep development natural: ...Nc6, ...Bf5 or ...Bg4, ...e6, and castling.
  • With ...Nxc3: use the damaged c-pawns and queen activity rather than drifting into passive defence.
  • After 3.e5: pick a system. ...d4 is combative, ...Nfd7 is French-like, and ...Ne4 is provocative.
  • Against Hector-style pressure: count tempi carefully. White’s early castling can turn a material-looking line into a development race.

Common mistakes

  • For Black: choosing 3...d4 without knowing the pawn-race structures.
  • For Black: playing 4...e6 automatically after Bc4 and accepting a cramped bishop without a clear plan.
  • For White: entering the 4.g3 line without respecting ...Qd5 and ...Qe6+.
  • For White: treating 3.e5 Nfd7 as a normal French without checking the early e6 possibility.
  • For both sides: memorising labels instead of the first real decision: 3.exd5 or 3.e5.

Study path

  1. Play the Scandinavian starting point against the computer twice, once choosing 3.exd5 and once choosing 3.e5.
  2. Study the Bc4 and ...Nb6 diagrams until you can explain why ...Nb6 is comfortable.
  3. Replay Lein vs Alburt for Black’s active handling of 3.exd5 structures.
  4. Study the 3.e5 d4 diagram and then replay Hector vs Kengis.
  5. Finish with the ...Nfd7 French-style diagram and replay one French-style model game.

Scandinavian Variation FAQs

Basics and move order

What is the Alekhine Defense Scandinavian Variation?

The Alekhine Defense Scandinavian Variation is the line 1.e4 Nf6 2.Nc3 d5, where Black immediately challenges White’s centre instead of allowing the usual 2.e5 knight chase. Use the Scandinavian starting point diagram to compare White’s two main choices, 3.exd5 and 3.e5.

Why is 2...d5 called the Scandinavian Variation?

It is called Scandinavian because Black’s second move mirrors the Scandinavian Defence idea of meeting e4 with an immediate ...d5. Review the Scandinavian starting point diagram to see how the move order differs from a normal 1.e4 d5 opening.

Is the Scandinavian Variation part of Alekhine Defense theory?

Yes, because it arises after 1.e4 Nf6 2.Nc3, so Black has started with Alekhine’s knight move before choosing the independent ...d5 setup. Use the replay group to see how strong players handled the crossover positions.

What is the main line after 1.e4 Nf6 2.Nc3 d5?

The main practical branch is 3.exd5 Nxd5 4.Bc4, when Black usually chooses ...Nb6 or ...Nxc3. Start with the Bc4 test diagram and then use its practice button to test the position against the computer.

Is 4...Nb6 equal after 3.exd5 Nxd5 4.Bc4?

4...Nb6 is considered one of Black’s cleanest equalising moves because the knight retreats with tempo against the bishop and Black can develop normally. Use the calm ...Nb6 equaliser diagram to practise White’s next plan.

Is 4...Nxc3 equal after 3.exd5 Nxd5 4.Bc4?

4...Nxc3 is also playable because Black removes a developed knight and can aim for straightforward development. Compare it with the 4.g3 Ekebjaerg diagram, where ...Nxc3 and early queen activity are central to Black’s comfort.

What is the downside of 4...e6 in the Scandinavian Variation?

4...e6 is solid, but it blocks Black’s light-squared bishop and may leave Black with a slightly less active version of the position. Use the branch map section to compare ...e6 with the more flexible ...Nb6 and ...Nxc3 choices.

What is the idea of 4.g3 in this line?

The 4.g3 idea prepares a kingside fianchetto and was associated with Ove Ekebjaerg in correspondence play. Study the Ove Ekebjaerg 4.g3 idea diagram to see why Black’s ...Qd5 and ...Qe6+ plan is important.

Why does Black answer 4.g3 with 4...Nxc3?

Black captures on c3 to damage White’s queenside structure and then uses queen activity to prevent White from getting an effortless fianchetto setup. Use the 4.g3 diagram and practice button to test whether White can coordinate quickly enough.

Why is 6.Nf3 awkward in the 4.g3 line?

After 4.g3 Nxc3 5.bxc3 Qd5, 6.Nf3 can allow ...Qe4+ ideas, making White’s development uncomfortable. Use the Ove Ekebjaerg 4.g3 idea diagram to practise the safer queen trade route.

What is the point of 6.Qf3 in the Ekebjaerg line?

6.Qf3 challenges Black’s queen and reduces the danger of an awkward check on e4. Replay the Scandinavian model games and compare how early queen exchanges change the character of the game.

What is Black’s plan after 8.Nxe2 Bd7 in the 4.g3 line?

Black often plans ...Bc6, ...Nc6, ...g6 and queenside castling, reaching a comfortable position with easy development. Use the Ove Ekebjaerg 4.g3 idea diagram as the starting practice position.

3.e5 branches and transpositions

What happens if White plays 3.e5 instead of 3.exd5?

After 3.e5, Black can choose among 3...d4, 3...Nfd7, 3...Ne4 and even rarer retreats. Use the combative 3.e5 d4 branch diagram to practise the sharpest version first.

What is the idea of 3...d4 against 3.e5?

3...d4 gains space and immediately asks White’s c3-knight where it is going. The 3.e5 d4 diagram shows the critical crossroads: Nce2, exf6, or slower development.

What is the sharp pawn race after 3...d4?

The sharp pawn race is 4.exf6 dxc3 5.fxg7 cxd2+ 6.Bxd2 Bxg7, where both sides accept structural oddities for speed. Use the Hector-style pawn race diagram to practise White’s development plan.

Why can White castle quickly in the 3...d4 pawn race?

After the pawn race, White often clears the d-file and can develop rapidly despite material imbalance. Use the Hector-style pawn race diagram and check how fast White can bring the rook to e1 or d1.

What is 3...Nfd7 trying to do?

3...Nfd7 keeps the centre flexible and can transpose into a French Defence Steinitz structure after 4.d4 e6. Use the ...Nfd7 French-style transposition diagram to decide whether White should play normally or try 4.e6.

Can the Scandinavian Variation transpose to the French Defence?

Yes, after 1.e4 Nf6 2.Nc3 d5 3.e5 Nfd7 4.d4 e6, the structure resembles a French Defence Steinitz. Use the ...Nfd7 French-style diagram to practise the pawn-chain plans.

What is the sharp alternative to 4.d4 after 3...Nfd7?

White can try 4.e6!?, aiming for immediate disruption before Black completes a French-style setup. Use the branch map section to compare this sharper try with the calmer 4.d4 e6 route.

What is the idea of 3...Ne4?

3...Ne4 is provocative: Black plants the knight in the centre and asks White to prove it is misplaced. Use the 3...Ne4 option diagram to practise Nce2, Qf3 and Nxe4 approaches.

Is 3...Ng8 playable after 3.e5?

3...Ng8 is rare and deliberately provocative, aiming to claim that White’s advanced e-pawn can still be attacked later. Use the replay lab rather than the main diagram set for rare sidelines.

Why do some Alekhine authors prefer 2...e5 over 2...d5?

Some authors prefer 2...e5 because the 2...d5 Scandinavian Variation gives White several practical tries, especially the 3.e5 systems associated with Jonny Hector. Use the Hector-style replay group to see why White can create pressure.

Why is Jonny Hector important in this variation?

Jonny Hector regularly used 2.Nc3 against the Alekhine and scored well in 2...d5 structures, especially with ambitious 3.e5 ideas. Load the Hector vs Kengis or Hector vs Baburin replay to study his handling.

Is the Scandinavian Variation good for club players as Black?

It can be useful if you want an independent answer to 2.Nc3 and are willing to study the 3.e5 branches. Start with the branch map and then practise the Scandinavian starting point against the computer.

Practical repertoire choices

Is the Scandinavian Variation safe for Black?

It is playable but not autopilot-safe, because passive play can let White keep a theoretical edge in several 3.e5 lines. Use the adviser to choose whether you should study the 3.exd5 or 3.e5 branch first.

What should White play against the Scandinavian Variation?

White can choose 3.exd5 for a cleaner development game or 3.e5 for sharper practical pressure. Use the Scandinavian starting point diagram and play both options against the computer.

What should Black study first in this variation?

Black should first learn 3.exd5 Nxd5 4.Bc4 and the replies ...Nb6 and ...Nxc3, then move to the sharper 3.e5 d4 and 3...Nfd7 branches. Use the study path section to follow that order.

What is the biggest tactical danger for Black?

The biggest danger is entering the 3.e5 lines without knowing whether the knight belongs on d7, e4, or whether ...d4 is justified. Use the 3.e5 d4 and 3...Ne4 diagrams as your tactical training pair.

What is the biggest strategic danger for White?

White can overextend or trade into a harmless position if the centre is not supported by quick development. Use the ...Nb6 equaliser and 4.g3 diagrams to practise keeping the initiative.

Does 2.Nc3 avoid normal Alekhine theory?

It avoids many mainline Alekhine positions, but Black can still choose independent systems with 2...d5 or transpose with 2...e5. Use the page map links to compare this page with the wider Alekhine Defence guide.

Should Black always recapture 3.exd5 with 3...Nxd5?

In this variation, 3...Nxd5 is the standard recapture because it keeps development natural and challenges White to justify Bc4 or g3. Use the Bc4 test diagram to practise Black’s next choice.

Why is the bishop on c4 annoying for Black?

The bishop develops with tempo, eyes f7, and can force Black’s knight to make another decision. Use the Bc4 test diagram and test ...Nb6 in the practice board.

Why does ...Qd5 appear in the 4.g3 line?

...Qd5 uses the weakened c-pawn structure and threatens awkward checks or queen exchanges before White’s setup is complete. Use the Ove Ekebjaerg diagram to understand the queen route.

Which supplied replay is best for the 3.exd5 branch?

Lein vs Alburt is a strong starting replay for 3.exd5 Nxd5 4.Bc4 Nb6 because it shows Black’s active piece play. Load the Classical 3.exd5 replay group in the replay lab.

Replay and training questions

Which supplied replay is best for the 3.e5 d4 branch?

Hector vs Kengis is a useful model because it shows the pawn-race structure after 3.e5 d4 4.exf6. Load the Hector-style pressure replay group in the replay lab.

Which supplied replay is best for the French-style branch?

Nunn vs Howell and Hector vs Baburin show the 3.e5 Nfd7 structures that can resemble French Defence play. Use the French-style replay group in the replay lab.

Can White use this line as a surprise weapon?

Yes, 2.Nc3 followed by either 3.exd5 or 3.e5 can be a practical surprise weapon against Alekhine players who only know 2.e5. Start with the adviser and choose the branch that matches your style.

Can Black use this line as a surprise weapon?

Yes, 2...d5 can surprise White players who expected 2...e5 or a direct transposition. Use the Scandinavian starting point diagram to rehearse the first decision before trying it in games.

How should I train this page quickly?

Train the starting position, then the Bc4 line, then one sharp 3.e5 branch, and finish by replaying one model game. Use the practice buttons under the diagrams and the replay lab as the four-step routine.

What is the simplest Black repertoire from this page?

A simple Black repertoire is 3.exd5 Nxd5 4.Bc4 Nb6, and against 3.e5 choose either 3...Nfd7 into French-style play or 3...d4 if you want sharper play. Use the adviser to choose between solid and combative branches.

What is the simplest White repertoire from this page?

A simple White repertoire is 3.exd5 Nxd5 4.Bc4, while a sharper repertoire uses 3.e5 and prepares for ...d4 and ...Nfd7. Use the branch map and replay lab to decide which route suits you.

Does the Scandinavian Variation lead to queenless middlegames?

Sometimes, especially in the 4.g3 line where Qf3 and Qe2 can force queen exchanges. Use the Ove Ekebjaerg diagram to practise the queenless structure.

Does the Scandinavian Variation lead to attacking games?

Yes, especially after 3.e5 d4 or 3...Ne4, where development and king safety become urgent. Use the Hector-style pawn race and 3...Ne4 diagrams to practise attacking decisions.

What should I remember most from this page?

Remember that 2...d5 is not just a sideline: it creates a choice between clean 3.exd5 development and sharp 3.e5 independent play. Use the Scandinavian starting point diagram and replay lab before adding it to your repertoire.

Train the Scandinavian Variation

Start from the first diagram, choose your branch, then test the same structure in the replay lab. This page works best as a decision trainer rather than a memorisation sheet.
