Sicilian Defense Open Najdorf Lipnitsky Attack
Sicilian Defense
Definition
The Sicilian Defense is the family of openings that begins with the moves 1. e4 c5. Black immediately contests the center from the flank rather than mirroring White’s e-pawn with …e5, creating an asymmetrical pawn structure that leads to rich strategic and tactical play.
How It Is Used in Chess
After 1…c5, Black aims for:
- Rapid queenside expansion (…b5, …a6) and pressure along the half-open c-file.
- Counter-attacking chances instead of passive defense.
- Positions where piece activity can compensate for a small spatial deficit.
White, in turn, chooses between “Open” systems (2. Nf3 followed by 3. d4) and various Anti-Sicilians such as the Alapin (2. c3) or Grand Prix (2. f4).
Strategic & Historical Significance
The Sicilian is the most popular defense to 1. e4 at every level—from scholastic tournaments to world-class events—because it unbalances the game early. World Champions from Bobby Fischer to Magnus Carlsen have employed it regularly.

Interesting Facts
- The earliest known game with 1…c5 dates back to Giulio Cesare Polerio (late 16th century).
- In modern databases, roughly a third of all master-level games beginning with 1. e4 continue with 1…c5—more than any other reply.
Open Sicilian
Definition
The term “Open Sicilian” refers to the main branch that arises after
1. e4 c5 2. Nf3 d6/…Nc6 3. d4 cxd4 4. Nxd4
White sacrifices the d-pawn temporarily to open central lines and accelerate development.
Usage and Typical Move Order
- 1. e4 c5
- 2. Nf3 (prepares d4)
- …d6 / …Nc6 / …e6 (Black’s setup)
- 3. d4 cxd4 4. Nxd4 – the pawn exchange “opens” the position.
From here the Open Sicilian branches into famous variations such as the Najdorf, Dragon, Scheveningen, and Sveshnikov.
Strategic Themes
- Imbalance: White enjoys a spatial plus and central majority; Black obtains a half-open c-file and long-term queenside pawn majority.
- Pace vs. Structure: White strives for rapid piece activity (often kingside attacks), while Black relies on structural counterplay and pawn breaks like …d5 or …b5.
Historical Note
The distinction “Open” vs. “Closed/Anti-Sicilian” emerged in the early 20th century as theory exploded. By the 1950s the Open Sicilian had become the proving ground for cutting-edge preparation—epitomised by the battles of Fischer, Tal, and later Kasparov.
Najdorf Variation
Definition & Baseline Moves
The Najdorf is a flagship Open Sicilian system beginning
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6
Named after Polish-Argentine grandmaster Miguel Najdorf, the move 5…a6 prevents White’s pieces from landing on b5 and prepares …e5 or …b5.
Strategic Ideas
- Flexibility: Black can choose setups with …e5 (Scheveningen-style), …e6 (Classical), or the sharp …g6 (Dragon-like).
- Queenside Counterplay: …b5–b4 drives away the c3-knight, weakening White’s e4-pawn.
- Central Breaks: Timely …d5 often equalises or seizes the initiative.
Historic Significance
The Najdorf became the critical test of 1. e4 during the 1960s–1990s. Bobby Fischer made it his main weapon as Black, while Garry Kasparov scored many brilliancies as White and Black.
Classic Game
Kasparov – Anand, WCC Candidates 1991 featured the legendary Poisoned Pawn line (6. Bg5 e6 7. f4 Qb6 8. Qd2 Qxb2). Kasparov’s deep preparation paved the way for victory and highlighted the Najdorf’s tactical richness.
Interesting Tidbits
- The ECO codes B90–B99 are devoted entirely to Najdorf sub-variations—more pages than some whole openings receive.
- Najdorf himself lived to see computers confirm the soundness of his creation; he quipped, “At last a partner that never forgets my move 5…a6!”
Lipnitsky Attack (in the Najdorf)
Definition & Move Order
The Lipnitsky Attack is a sharp anti-Najdorf weapon characterised by
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4
Named after Ukrainian master and theoretician Ilya Lipnitsky, the early pawn thrust 7. f4 bolsters the e5 square, supports a potential g-pawn storm, and keeps options open for long-side castling.
Strategic Aims
- Space & Initiative: The f-pawn claims central real estate and prepares 8. Qf3 or 8. Qd2 with rapid mobilisation.
- Flexible King Placement: White can castle queenside for a pawn-storm race, or remain in the centre if favourable.
- Pressure on d6 & e6: The Bg5-Nxd4 battery pins the f6-knight, making …d5 breaks harder for Black.
Typical Continuations
- 7…Qb6 – transposes to the Poisoned Pawn with extra wrinkles because the pawn on f4 discourages …h6-g5 ideas.
- 7…Be7 8. Qf3 Qc7 9. O-O-O – both sides prepare opposite-wing attacks.
- 7…Nbd7 attempting early …b5, when 8. Qf3 or 8. Qe2 keeps play razor-sharp.
Historical & Practical Notes
Lipnitsky popularised the setup in Soviet championships of the early 1950s, and it later resurfaced in the repertoires of attacking players such as Alexander Beliavsky and Judit Polgár. While less common than the English, Sozin, or Poisoned Pawn attacks, it remains a potent surprise weapon—especially rapid-time controls.

Interesting Facts
- Ilya Lipnitsky’s classic book “Questions of Modern Chess Theory” (1956) was revered by Fischer, who reportedly carried it to tournaments despite being unable to read Russian.
- Computer engines rate 7. f4 as fully sound, giving it a renewed lease of life in 21st-century blitz and bullet play.
