Queens Gambit Accepted Winawer Defense
Queen's Gambit Accepted (QGA)
Definition
The Queen's Gambit Accepted is an opening that begins with the moves 1.d4 d5 2.c4 dxc4. Black “accepts” White’s c-pawn, temporarily giving up central control in order to gain a pawn and open lines for quick piece development. The ECO codes D20-D29 are devoted to this opening.
Typical Move-Order and Branches
- 1.d4 d5 2.c4 dxc4 (the acceptance)
- 3.Nf3 (or 3.e4, 3.Qa4+, 3.e3) … Nf6 4.e3 (or 4.Nc3, 4.e4) … e6 5.Bxc4 c5 – “Main Line”
- Alternative counter-gambit: 3.Nf3 e5?! – the Winawer Counter-Gambit (see note under Winawer Defense)
Strategic Themes
- White: Regain the c-pawn (usually with Bxc4), build a broad center with e4/e3 and d4, use rapid development to launch an initiative before Black completes piece coordination.
- Black: Accept the pawn only temporarily, strike back in the center with …c5 or …e5, exchange minor pieces to neutralize White’s space advantage, and aim for pawn symmetry once the c-pawn is returned.
Historical Significance
The QGA is one of the oldest recorded defenses to 1.d4, appearing in the 19th-century games of Paul Morphy and Wilhelm Steinitz. For decades it had a reputation for being slightly risky for Black, but grandmasters such as Tigran Petrosian, Boris Spassky, and later Vladimir Kramnik demonstrated that accurate play yields full equality. The opening featured in several World Championship matches, including Anand–Carlsen (2013) and Carlsen–Karjakin (2016), cementing its modern respectability.

Interesting Facts
- Early 20th-century manuals considered 2…dxc4 “greedy and suspect.” Modern engines rate the line as fully sound.
- Because Black is ready to give the pawn back, masters sometimes joke that the “Queen’s Gambit Acquitted” would be a more descriptive name.
- The QGA was Garry Kasparov’s surprise choice against IBM’s Deep Blue in 1997; he equalized comfortably but ultimately lost the match.
Winawer Defense
Definition
The term “Winawer Defense” most commonly refers to the Winawer Variation of the French Defense: 1.e4 e6 2.d4 d5 3.Nc3 Bb4. Named after the 19th-century Polish master Szymon Winawer, the line sees Black pinning the knight on c3, thereby increasing pressure on d4 and preparing rapid counterplay on the queenside.
Core Ideas
- Black: Exert long-term pressure on d4, often surrendering the light-squared bishop in exchange for structural targets (isolated or doubled c-pawns). Counterplay revolves around …c5, …Ne7-f5/h6, and pawn storms with …f6 or …g5 in sharp lines.
- White: Seize space with e5 and c2-c4, build a kingside initiative (Qg4 and h2-h4 in the Poisoned Pawn), or adopt quieter positional plans with Nf3, Bd3, and c3.
Main Branches at a Glance
- 4.e5 c5 5.a3 Bxc3+ 6.bxc3 – “Classical Winawer”
- 4.e5 c5 5.a3 Bxc3+ 6.bxc3 Ne7 7.Qg4 – “Poisoned Pawn Variation”
- 4.exd5 exd5 5.Bd3 – the positional (Exchange-like) approach
Historical & Practical Significance
The Winawer boasts a rich pedigree: it was a favorite of Mikhail Botvinnik, Viktor Korchnoi, and Garry Kasparov when they needed double-edged play with Black. Bobby Fischer employed it to defeat Wolfgang Unzicker (Buenos Aires 1960) in a sparkling attacking game. Its theoretical status remains lively; elite players such as Alireza Firouzja and Ian Nepomniachtchi still unleash the Winawer to unbalance classical struggles.

Anecdotes & Trivia
- Szymon Winawer introduced 3…Bb4 at the Vienna tournament of 1887—well over a decade before the French Defense itself was formally named!
- In the “Poisoned Pawn,” both sides willingly enter labyrinthine computer-checked lines that can run 25+ moves of theory—magnets for opening theoreticians and engine aficionados alike.
- Confusingly, “Winawer Counter-Gambit” (3…e5) in the Queen’s Gambit Accepted also bears Winawer’s name. Always check the move order to know which Winawer a commentator is discussing.
