Benko Gambit Declined: Bishop Attack

Before the first move

The Benko Gambit is a provocative opening where Black sacrifices a pawn to gain long-term pressure on the queenside. In this variation, White declines the immediate pawn grab and plays the Bishop Attack, aiming to disrupt Black's coordination and pin the critical f6-knight before the battle for the b5-pawn truly begins.

1. d4White

White starts with d4, a move that focuses on central control and long-term stability. While e4 often leads to tactical skirmishes, d4 usually invites a more positional struggle, allowing for a variety of responses from Black.

1... Nf6Black · your move

Develop your knight to f6. This is the most flexible response to White's d4, preventing White from immediately occupying the center with e4 and preparing to see how White intends to continue their development.

Other paths here: Na6 (Australian Defense) · g5 (Borg Defense: Borg Gambit) · b6 (English Defense) · e5 (Englund Gambit)

2. c4White

White plays c4, establishing the Queen's Gambit structure. While the London System or the Tartakower Attack with g3 are popular alternatives, this move is the most ambitious way to challenge Black's setup and dominate the center.

Other paths here: f4 (Canard Opening) · g4 (Indian Defense: Gibbins-Weidenhagen Gambit) · e4 (Indian Defense: Omega Gambit) · d5 (Indian Defense: Pawn Push Variation)

2... c5Black · your move

Strike at the center with c5. You are challenging White's d4 pawn immediately. This move signals your intent to play a Benoni-style structure, creating an asymmetrical position where you can fight for the initiative.

Other paths here: g5 (Indian Defense: Medusa Gambit) · b5 (Indian Defense: Pyrenees Gambit) · a6 (Indian: 2.c4 a6) · Nc6 (Mexican Defense)

3. d5White

White pushes to d5, the most principled response to the Benoni challenge. White could also choose to develop with Nf3 or trade with dxc5, but the pawn push is the most aggressive way to claim a space advantage.

Other paths here: Nf3 (English Opening: Symmetrical Variation, Anti-Benoni Variation) · e3 (Benoni: 2...c5 3.e3) · dxc5 (Benoni: 3.dxc5)

3... b5Black · your move

Offer the b5-pawn. This is the Benko Gambit. You are sacrificing a wing pawn to open the a and b files for your rooks, aiming for permanent pressure against White's queenside pawns and pieces.

Other paths here: e5 (Benoni Defense: Czech Benoni Defense) · d6 (Benoni Defense: Hromádka System) · a6 (Benoni: 3.d5 a6) · g6 (Benoni: 3.d5 g6)

4. Bg5White

White plays Bg5, declining the gambit in favor of development. This Bishop Attack avoids the main lines of the Benko. White could have played Nf3 or the Sosonko Variation with a4, but this pin creates immediate tactical problems for Black.

Other paths here: e4 (Benko Gambit Declined: Hjørring Countergambit) · Nf3 (Benko Gambit Declined: Main Line) · f3 (Benko Gambit Declined: Pseudo-Sämisch) · Nd2 (Benko Gambit Declined: Quiet Line)

Where you stand

The position is highly unbalanced. White has avoided the typical Benko pressure but must deal with the tension on the queenside while managing the pin on f6. Black will likely look to challenge the bishop with Ne4 or continue development with g6 and Bg7, leading to a complex middlegame where both sides have clear chances to seize the initiative.

• f6-e4 Jump the knight to e4 to harass the bishop
• g5-h4 Retreat the bishop to maintain the pin
• g7-g6 Prepare to fianchetto the bishop on g7
• b1-d2 Develop the knight to support the center
