QGA: 4.e3 a6

Before the first move

The Queen's Gambit Accepted is a sharp fight for central control. White offers a pawn to lure Black away from the d5-square, while Black aims to use that extra time to expand on the queenside. In this variation, White prepares to recapture the pawn while Black prepares a quick counter-attack with pawn thrusts.

1. d4White · your move

Push your pawn to d4 to claim immediate control of the center. This move opens lines for your queen and dark-squared bishop, establishing a solid foothold in the middle of the board for your opening strategy.

1... d5Black

Black replies with d5, the most solid response to d4. While alternatives like the English Defense with b6 or the sharp Englund Gambit with e5 exist, this move leads to the most reliable structures for Black.

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

2. c4White · your move

Slide your pawn to c4 to offer the Queen's Gambit. You are attacking Black's central d5-pawn, hoping to trade your wing pawn for their center pawn or force them to give up the center entirely.

2... dxc4Black

Black plays dxc4, accepting the gambit. While the Austrian Defense with c5 or the Baltic with Bf5 are popular ways to decline the pawn, this capture leads to open positions where both sides have clear targets.

Other paths here: c5 (Queen's Gambit Declined: Austrian Defense) · Bf5 (Queen's Gambit Declined: Baltic Defense) · Nf6 (Queen's Gambit Declined: Marshall Defense) · b5 (Queen's Gambit Declined: Zilbermints Gambit)

3. Nf3White · your move

Develop your knight to f3. This is a flexible move that prevents Black from playing e5 and prepares to recapture the c4-pawn. It also keeps your options open for how to develop your kingside.

Other paths here: Nc3 (QGA: 3.Nc3) · Qa4+ (Queen's Gambit Accepted: Accelerated Mannheim Variation) · e3 (Queen's Gambit Accepted: Old Variation) · e4 (Queen's Gambit Accepted: Saduleto Variation)

3... Nf6Black

Black replies with Nf6, reinforcing the center. This is more standard than the Janowski-style Bg4 or the Slav Gambit with b5, as it maintains a flexible defense while preparing for kingside development.

Other paths here: Bg4 (QGA: 3.Nf3 Bg4) · Nd7 (Queen's Gambit Accepted: Godes Variation) · c5 (Queen's Gambit Accepted: Gunsberg Defense) · e6 (Queen's Gambit Accepted: Rosenthal Variation)

4. e3White · your move

Move your pawn to e3. This solidifies your center and opens the diagonal for your light-squared bishop to finally recapture the pawn on c4, completing your primary goal in the opening phase.

Other paths here: g3 (QGA: 3.Nf3 Nf6 4.g3) · Qa4+ (Queen's Gambit Accepted: Mannheim Variation) · Nc3 (Queen's Gambit Accepted: Showalter Variation)

4... a6Black

Black plays a6, preparing the b5 expansion. This is a key alternative to the traditional e6 or the Smyslov Variation with g6, signaling that Black intends to fight for the queenside initiative immediately.

Other paths here: c5 (QGA: 4.e3 c5) · Bg4 (Queen's Gambit Accepted: Janowski-Larsen Variation) · g6 (Queen's Gambit Accepted: Smyslov Variation) · Be6 (Queen's Gambit Accepted: Winawer Defense)

Where you stand

The position is balanced but full of tension. White will likely recapture on c4 and seek a central breakthrough, while Black will use the a6 move to launch a b5 expansion. Both sides must balance their development with the looming battle for the c4 and d4 squares.

• f1-c4 Recapture the pawn on c4
• b7-b5 Expand on the queenside with b5
• e1-g1 Castle kingside for king safety
• c8-b7 Fianchetto the bishop to b7
