Sicilian Defense: Pelikan Open & Sveshnikov Exchange
Sicilian Defense – Open Pelikan Variation
Definition
The Pelikan Variation (also called the Lasker–Pelikan or, in its modern form, the Sveshnikov) is a razor-sharp branch of the Open Sicilian in which Black immediately challenges the centre with …e5. The tabiya arises after
1. e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6.
By pushing the e-pawn two squares, Black concedes a permanent hole on d5 and weakens the d6 pawn, but gains space, frees the light-squared bishop, and seizes the initiative.
Typical Move Order
- e4 c5
- Nf3 Nc6
- d4 cxd4
- Nxd4 Nf6
- Nc3 e5
- Ndb5 d6
- Bg5 a6
- Na3 b5
- Bxf6 gxf6 (or 9…Qxf6)
The position is dynamically balanced: White enjoys pressure on the d5 square and a lead in development, while Black owns the bishop pair and a pawn duo (e5–d6) ready to roll in the centre.
Strategic Themes
- d5 outpost: White often maneuvers a knight to d5 (via c3–d5 or e3–d5) where it can never be chased by a pawn.
- Bishop pair & pawn majority: Black seeks …f5 or …b4 to generate kingside/queenside play and open lines for the bishops.
- Structural imbalance: Black’s doubled f-pawns after Bxf6 gxf6 give open g- and f-files for counterplay but can also become endgame targets.
- Piece activity over structure: The entire opening embodies modern chess philosophy: accept structural weaknesses in return for active pieces and the initiative.
Historical Notes
Czech-Argentine GM Jiří Pelikán employed 5…e5 during the 1950s, but the line exploded in popularity when GM Evgeny Sveshnikov analyzed it deeply in the 1970s. His fearless advocacy at top level (often beginning in the USSR Championship, Minsk 1974) convinced the chess world that the variation was not only playable but dangerous. Modern engines still agree with his verdict—evidence of how far ahead of his time Sveshnikov was.

Interesting Facts & Anecdotes
- GM Sveshnikov claimed he had analysed the line “for ten thousand hours,” often testing novelties in simultaneous exhibitions before unveiling them in tournaments.
- During the 2018 World Championship, Magnus Carlsen adopted the Pelikan/Sveshnikov as his main defence, scoring an impressive +1 =9 –0 against Fabiano Caruana.
- The move 5…e5 was once thought “positionally suicidal.” Today it is a mainstay at every level—proof that engines and new ideas can overturn dogma.
Sveshnikov Exchange Variation
Definition
The Exchange Variation of the Sveshnikov occurs when White immediately swaps a knight on d5 for Black’s knight on f6, producing an open e- and d- file structure:
1. e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6 7.Nd5 Nxd5 8.exd5.
White eliminates the f6-knight, fixes a backward pawn on d6, and stakes a claim to the d5 square. Black, in turn, maintains the bishop pair and strives for counterplay with …f5, …g6, and piece pressure on the central pawns.
Key Ideas for Each Side
- White
- Plant a knight or even a bishop on d5, supported by c2–c4 or c2–c3.
- Target the d6 pawn with Rd1, Bd3, and sometimes Nb5–d6.
- Transition to a favourable endgame where the weak squares outweigh Black’s bishop pair.
- Black
- Break with …f5 (often preceded by …Ne7–g6) to free the position and attack White’s king.
- Use the bishops on long diagonals, occasionally sacrificing the d6 pawn for activity.
- Counterplay on the queenside with …b5, mirroring the main Pelikan.
Theoretical Status
The Exchange line is currently considered one of White’s most solid tries against the Sveshnikov. Engines evaluate the position as roughly equal, but practical winning chances exist on both sides thanks to the unbalanced pawn structure.

Historical & Practical Significance
Although Emanuel Lasker once essayed similar ideas in 1910, the variation gained prominence only after the Sveshnikov boom in the 1970s. Modern top players—including Kramnik, Giri, and Nepomniachtchi—often choose the Exchange line as a “low-risk, high-pressure” weapon when they need to play for two results.
Trivia & Nuggets
- GM Evgeny Sveshnikov himself preferred not to meet 7.Nd5 with 7…Nxd5; he believed the resulting structure dampened his beloved bishop pair!
- Because the line contains an early “exchange” (Nxd5/Nxd5), some databases label it “Exchange,” even though no queens or rooks leave the board.
- The d5 outpost is so valued that in several games White willingly gives up the exchange (R vs minor piece) to keep a monster knight anchored there.
