The Old Benoni Defence: A Comprehensive Analysis

Introduction

The Old Benoni Defence is an aggressive and flexible chess opening that arises after the moves:

1. d4 c5

Unlike its more famous counterpart, the Modern Benoni (which typically arises after 1. d4 Nf6 2. c4 c5 3. d5 e6), the Old Benoni Defense is characterized by Black’s immediate advance with 1…c5, challenging White’s center right from the start. This move signals Black’s intent to create imbalances in the position, often leading to dynamic and counterattacking play.

Although the Old Benoni has never been a mainstream choice at the highest levels of chess, it has been employed by various players who favor unconventional and aggressive approaches.

Origins and History

The Benoni Defense, in general, dates back to the 18th and 19th centuries. The term “Benoni” means “son of sorrow” in Hebrew and was first documented in a chess manuscript from 1825 by Aaron Reinganum. The name likely originates from the struggles Black faces in maintaining dynamic equality.

The Old Benoni, specifically, was seen in various historical games but never gained significant traction among elite players. This is largely because White can seize an early initiative with precise play. However, due to its surprise value and potential to create unbalanced positions, it has remained a weapon in the arsenal of club players and enterprising grandmasters.

Notable Historical Games

One of the earliest recorded instances of the Old Benoni can be found in casual games from the 19th century, but its effectiveness became more prominent when players like Alexander Alekhine and Bent Larsen experimented with similar ideas in their games.

Key Strategic Concepts

The Old Benoni is an unorthodox response to 1. d4, as Black immediately stakes a claim on the center with 1…c5 rather than opting for traditional responses like 1…d5 or 1…Nf6.

Key Ideas for Black:

• Immediate counterplay: The early …c5 looks to disrupt White’s central control.
• Pawn breaks: Black often seeks …e6 and …d5 or aims for …b5 and queenside expansion.
• Piece activity: The fianchetto of the kingside bishop with …g6 and …Bg7 is a common setup.
• Psychological advantage: Since White is more accustomed to standard defenses (like the Queen’s Gambit or King’s Indian), an early …c5 can be unsettling.

Key Ideas for White:

• Strong central control: White can opt for c3 followed by d5 to create a dominant pawn center.
• Development with tempo: Moves like Nc3 and e4 can force Black into a passive setup.
• Space advantage: White’s early moves often grant them superior control of the board.

Variations and Subsystems

The Old Benoni has several key branches, each with its own unique ideas and plans.

1. The Traditional Main Line

1. d4 c5
2. d5

Here, White immediately closes the center, leading to a structure similar to the Benoni proper. Black has several continuations:

• 2…e5 (Czech Benoni Approach): Black grabs central space and aims for a solid, locked pawn structure.
• 2…d6: Aiming for a flexible setup, often preparing …g6 and …Bg7.
• 2…Nf6: Preparing …g6 and kingside fianchetto development.

2. The Semi-Benoni Approach

1. d4 c5
2. dxc5

By capturing on c5, White accepts a temporary pawn sacrifice. Black can respond with:

• 2…e6, looking to regain the pawn and establish a strong central hold.
• 2…Qa5+, immediately attacking c5 and gaining tempo.

3. The Snake Variation (1. d4 c5 2. d5 f5)

A hyper-aggressive response where Black launches an immediate counterstrike against White’s center. This leads to double-edged positions, often similar to the Dutch Defense but with an early …c5 thrust.

4. The Hjørring Countergambit (1. d4 c5 2. d5 Na6)

A rare and speculative attempt by Black to develop in an unorthodox fashion. The knight on a6 may later reposition to c7 or b4 to pressure White’s center.

Famous Grandmasters Who Have Used the Old Benoni

While the Old Benoni is not frequently seen at the elite level, it has occasionally been employed by creative and aggressive players:

1. Bent Larsen

Larsen was known for his offbeat and aggressive opening choices. He experimented with many unorthodox openings, including the Old Benoni, to throw opponents out of their preparation.

2. Alexander Alekhine

Alekhine, one of the greatest attacking players in history, occasionally employed the Benoni structure, favoring dynamic and complex positions.

3. Mikhail Tal

The eighth world champion, Tal, was known for his tactical brilliance. He occasionally played Benoni setups in order to generate rich attacking chances.

Grandmaster Opinions on the Old Benoni

The Old Benoni is not a mainstream opening, and many elite players consider it slightly dubious due to White’s strong response with 2. d5. However, it still has its supporters who appreciate its dynamic potential.

• Garry Kasparov: “The Benoni is not for the faint-hearted. If Black is willing to take on the burden of an early pawn push, he must also be prepared to fight for every square.”
• Nigel Short: “I wouldn’t recommend the Old Benoni against well-prepared opponents, but in blitz and rapid games, it has practical value.”
• John Watson: “The Old Benoni is not theoretically sound, but in practical play, it can lead to interesting, double-edged positions that favor aggressive players.”
