Sicilian Defense: Open Pelikan and Sveshnikov Variations

Sicilian Defense – Open Pelikan Variation

Definition

The Pelikan Variation is a sharp branch of the Open Sicilian that arises after the moves 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5. Black immediately challenges the d4–knight and gains spatial control in the centre at the cost of creating a backward d-pawn and weakening the d5-square. Until the late 1970s the position after 5…e5 was usually called the “Lasker–Pelikan Variation,” honouring Emanuel Lasker (who essayed the idea in 1910) and the Czech-Argentine master Jiří (Jorge) Pelikán, who analysed it deeply in the 1950s.

Typical Move Order

  1. 1. e4 c5
  2. 2. Nf3 Nc6
  3. 3. d4 cxd4
  4. 4. Nxd4 Nf6
  5. 5. Nc3 e5
  6. 6. Ndb5 d6
  7. 7. Bg5 Be7 (the tell-tale Pelikan move; 7…a6 would funnel play into the Sveshnikov)*

Strategic Ideas

  • Black’s ambitions: Grab central space with …e5 and prepare …d5 in one leap if allowed. The bishop pair often provides dynamic counterplay.
  • White’s ambitions: Exploit the weak d5-square, the backward d6-pawn, and the hole on f5. A typical manoeuvre is Nb5–d5 followed by c2-c3, Bf1-c4, or even a kingside pawn storm with g2-g4.
  • Imbalance: Black accepts structural weaknesses (holes on d5 and f5) for activity. This leads to highly unbalanced middlegames rich in tactical motifs.

Historical Context & Notable Games

  • Lasker – Tarrasch, Berlin 1910: Although the modern move order differed, Lasker’s early …e5 ideas foreshadowed the Pelikan.
  • Pelikán’s Argentine analyses (1950s) revived interest, but the line remained rare until the computer era.
  • Kasparov – Ivanchuk, Linares 1991: A textbook example of White exploiting the dark-square holes; still mandatory study for Pelikan aficionados.
  • Today the pure Pelikan (with 7…Be7) has been somewhat eclipsed by the more resilient Sveshnikov set-up with …a6.

Example Miniature


In this (shortened) practice game, Black’s pair of bishops and central pawns generate enough energy to overcome structural weaknesses, illustrating a core Pelikan theme.

Interesting Facts

  • The position after 5…e5 violates “classical” opening rules (moving the same pawn twice, weakening d6), which long made theoreticians sceptical.
  • Pelikán was also a celebrated chess composer; his endgame studies mirror the tactical richness of his favourite variation.
  • Modern engines evaluate the starting Pelikan position as roughly equal, but concrete knowledge still outweighs “general principles.”

Sicilian Defense – Open Sveshnikov Variation

Definition

The Sveshnikov Variation is the modern, refined incarnation of the …e5 Sicilian, named after the Russian grandmaster Evgeny Sveshnikov, who championed it from the early 1970s onward. It is reached via the same first six moves as the Pelikan, but Black inserts …a6 before developing the kingside bishop: 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 e5 6. Ndb5 d6 7. Bg5 a6. This single tempo avoids several troublesome white ideas and gives Black dynamic chances that have stood up to world-class scrutiny.

Typical Continuations

  1. 8. Na3 b5 (main line)
     9. Nd5 Be7 10. Bxf6 Bxf6 11. c3
  2. 8. Na3 h6 9. Bxf6 Qxf6 10. Nc4 Qd8: a solid alternative popularised by Kramnik.
  3. 8. Nd5 Qa5+ 9. Bd2 Qd8: The “Kalashnikov-inspired” line with the queen excursion.

Strategic Themes

  • Fixed structural imbalances: Black weakens d5 and f5, but maintains quick piece activity and the potential to dominate dark squares (e.g., …Bg7, …f5).
  • Central pawn lever: Black dreams of …d5, often prepared by …Ne7–g6 or …Be7–g5.
  • White’s outpost: The knight on d5 is a bone in Black’s throat but can sometimes be exchanged by …Be6 or …Nxd5 followed by …Bg7.
  • Kingside pawn storms: Both sides eye pawn breaks (g4 for White, …f5 for Black) leading to razor-sharp play.

Historical Significance & Famous Battles

  • Sveshnikov’s own praxis: 1976 USSR Championship marked the line’s first high-level tests.
  • Kramnik, Leko, and Carlsen have all adopted the Sveshnikov when they needed a fighting weapon with Black.
  • Carlsen – Caruana, World Championship 2018 (Games 1, 5, 9): The variation was the main battleground of the match; Caruana’s high-level novelties sparked global discussion.
  • Kasparov – Topalov, Wijk aan Zee 1999: The legendary “Kasparov Immortal,” though starting from a Najdorf, transposed into Sveshnikov-type structures with the immortal 24. Rxd4!! combination.

Illustrative Game Fragment


This fragment (based on Caruana’s preparation for the 2018 match) shows key Sveshnikov motifs: the thematic exchange on f6, Black’s queenside expansion, and the ever-present …d5 break.

Interesting Facts

  • Evgeny Sveshnikov estimated he played over 3,000 games (including blitz) with his pet line, constantly refining its theory.
  • The variation’s theoretical reputation swung wildly: considered dubious in the 1960s, fashionable in the late 1980s, “refuted” again in the 1990s, and vindicated by modern engines in the 2000s.
  • The “Sveshnikov” was Carlsen’s only Black defence against 1. e4 in the entire 2018 World Championship, underscoring its durability at the very top.
  • Because the core position is so forcing, correspondence games (where engines are allowed) still discover novelties deep into move 25-30.
