Alekhine: Scandinavian, Exchange – Chess Openings
Alekhine’s Defense
Definition
The Alekhine (pronounced “Al-ye-khin”) is a hyper-modern reply to 1. e4 that begins 1…Nf6. Black immediately attacks the e-pawn and invites White to advance, planning to undermine the over-extended center later. It is named after the fourth World Champion, Alexander Alekhine, who introduced it in master play in 1921.
Main Line Moves
- 1. e4 Nf6 2. e5 Nd5 3. d4 d6 4. Nf3 g6 – Classical Variation
- 1. e4 Nf6 2. e5 Nd5 3. c4 – Four Pawns’ Attack
- 1. e4 Nf6 2. Nc3 – Two Pawns’ Attack (a quieter sideline)
Typical Plans & Strategy
- Black allows a broad white pawn center (e5, d4, c4) and then assaults it with …d6, …c5, and piece pressure.
- White chooses between maintaining the space advantage (Classical) or launching a direct pawn storm (Four Pawns’ Attack).
- Because Black’s knight is displaced to d5/b6, time is critical; a mis-timed strike can leave Black cramped or underdeveloped.
Historical & Practical Significance
Alekhine first played the line at Budapest 1921 against Endre Steiner and employed it successfully in the 1927 World Championship versus Capablanca. It remains a fighting weapon; grandmasters such as Lev Alburt, Vassily Ivanchuk, and Magnus Carlsen (rapid/blitz) have used it to unbalance quieter 1. e4 positions.
Illustrative Mini-Game
The diagram (after 8…e6) shows the typical tension: White owns space; Black readies …O-O and counterplay on c5 or f6.
Interesting Tidbits
- Alekhine reportedly conceived the opening while analyzing in a train compartment on the way to a tournament.
- The ECO codes are B02–B05. B02 starts with sidelines such as 2. Nc3; B05 covers the sharp Four Pawns’ Attack.
- Because the defense eschews immediate pawn symmetry, computer engines once disliked it; modern neural nets rate it more favorably.
Scandinavian Defense
Definition
The Scandinavian (or “Center Counter”) Defense arises after 1. e4 d5. Black instantly challenges the e-pawn, forcing an early open game and often leading to queen activity on the first few moves.
Main Branches
- 2. exd5 Qxd5 3. Nc3 Qa5 – Classical Main Line
- 2. exd5 Nf6 – Modern (Marshall) Variation, delaying the queen sortie
- 2. e5 – Advance Variation; White grabs space instead of capturing
Strategic Themes
- Black accepts a temporary lag in development (especially after …Qxd5) in exchange for a simple, solid structure.
- White tries to exploit the queen’s early exposure with Nc3, Bc4, and d4, but must beware of c-side pressure once the queen retreats to a5 or d6.
- The opening often transposes into Caro-Kann or French-type pawn structures, giving it crossover value in a player’s repertoire.
Historical Notes
The first recorded game dates back to 1475 (Lucena’s manuscript). It gained modern popularity after Bent Larsen revived it in the 1960s, famously defeating World Champion Anatoly Karpov with it in Montréal 1979.
Example Snapshot
After 5…c6, Black shores up the d5-square and readies …Bf5, obtaining a rock-solid setup.
Fun Facts
- Because it confronts 1. e4 head-on, some call it “the boxer’s reply” to the king-pawn.
- Magnus Carlsen employed the Modern Scandinavian (2…Nf6) against Anand in the 2014 World Championship rapid tie-break training games, sparking renewed interest.
- US GM Daniel Naroditsky once streamed 20 straight bullet wins with nothing but the Scandinavian, showcasing its practicality even at blistering speeds.
The Exchange
Definition
In chess jargon, the exchange refers to the relative trade of a rook for a minor piece (bishop or knight). A player who captures an opponent’s rook with a minor piece while losing that minor piece in return is said to “win the exchange” and usually gains material worth roughly 2 points.
Broader Meanings
- Piece Exchange: Any capture-and-recapture sequence that removes an equal type of piece from both sides (e.g., exchanging queens).
- Exchange Variation: An opening line in which one side deliberately trades central pawns early, simplifying the position—e.g., the Exchange French (3.exd5 exd5).
- Exchange Sacrifice (“RxN!”): Deliberately giving up a rook for a minor piece to obtain positional or tactical compensation, popularized by players like Tigran Petrosian and Garry Kasparov.
When It Is Used
“Winning the exchange” offers a tangible material edge, but the resulting position must still be favorable: doubled pawns, weak kings, or lack of open files can negate the advantage.
Strategic & Historical Significance
- Exchange sacrifices became a key motif in Soviet chess education; teachers emphasized dynamic factors over static material counts.
- Modern engines often uncover computer-like exchange sacs that humans later validate—e.g., AlphaZero’s immortal Rxg6!! games.
Classic Example
Petrosian – Spassky, World Championship 1966 (Game 10)

Quick Reference: Pros & Cons of Giving Up / Winning the Exchange
- Pros of Sacrificing
- Eliminate key defender (e.g., knight on f6)
- Open files for heavy pieces
- Create unstoppable passed pawns
- Pros of Winning
- Material edge for endgame
- Often easier technical conversion
- Psychological pressure on the opponent
- Cons (either side)
- Three minor pieces can sometimes outplay two rooks
- Closed positions lessen rook power
- Sacrificer must justify with concrete play
Did You Know?
- “The Exchange French” is so drawish at elite level that some tournaments banned its repeated use to encourage fighting chess.
- Garry Kasparov’s trademark exchange sac …Rxc3 in the Sicilian stunned Anand in their 1995 WCC match (Game 11).
- In problem-composition slang, a theme involving repeated exchange sacs is called a “Plachutta duel.”
