QGA: 4.e3 c5

Before the first move

The Queen's Gambit Accepted is a bold challenge to White's central control. Instead of holding the center, Black captures the c4-pawn, inviting White to regain it while seeking quick counter-development. In this line, Black immediately strikes back with c5 to prevent White from establishing a permanent central clamp.

1. d4White · your move

Move your pawn to d4. This classic opening move claims space in the center, controls the e5-square, and opens lines for your queen and dark-squared bishop. It is the foundation of many strategic systems.

1... d5Black

Black replies d5, the most solid and principled response to d4. Other popular choices include the flexible Nf6, the sharp Englund Gambit with e5, or the solid Horwitz Defense with e6, each leading to very different pawn structures.

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

2. c4White · your move

Offer the Queen's Gambit by moving your pawn to c4. You are challenging Black's d5-pawn and offering a temporary sacrifice to lure Black's pawn away from the center, which will help you dominate the middle later.

2... dxc4Black

Black plays dxc4, accepting the challenge. While the Slav Defense with c6 or the Orthodox Defense with e6 are more common at the highest levels, this capture forces White to spend time recovering the pawn.

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 crucial prophylactic move that prevents Black from immediately striking at the center with e5. It also prepares for your kingside development and eventual castling.

3... Nf6Black

Black replies Nf6, continuing development and eyeing the e4-square. Black could also try the sharp Slav Gambit with b5 or the Janowski-style Bg4 to pin the knight, but Nf6 remains the most reliable standard move.

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

Push your pawn to e3. This solid move opens the diagonal for your light-squared bishop to recapture the pawn on c4. It also strengthens your d4-pawn and prepares for kingside safety.

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... c5Black

Black plays c5, a thematic counter-strike. By attacking d4, Black avoids being squeezed. Other choices like a6 or e6 are more passive, but c5 forces a direct confrontation in the heart of the board.

Other paths here: a6 (QGA: 4.e3 a6) · 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 dynamically balanced. White will likely capture on c4 and castle quickly. Black aims to develop the queenside and use the c-file for pressure. Both sides must navigate the tension between the d4 and c5 pawns, which often leads to an isolated queen's pawn structure for White or a wide-open tactical struggle.
