History
Elias Stein (1748–1812), an Alsatian who settled in The Hague, recommended the defence as the best reply to 1.d4 in his 1789 book ''Nouvel essai sur le Jeu des échecs, avec des réflexions militaires relatives à ce jeu''. Siegbert Tarrasch rejected the opening as in his 1931 work '' The Game of Chess'', arguing that White should reply with the Staunton Gambit, with White being better after 2.e4 fxe4 3.Nc3 Nf6 4.Bg5 c6 5.f3 exf3.Practitioners
The Stonewall Dutch enjoyed a resurgence of interest in the 1980s and 1990s, when leading grandmasters (GMs) Artur Yusupov, Sergey Dolmatov, Nigel Short, and Simen Agdestein helped develop the system where Black plays an earlier ...d5 and places his dark-squared bishop on d6. This setup, termed the Modern Stonewall, has remained more popular than the traditional early ...Be7. Magnus Carlsen has used the Stonewall to score wins against Viswanathan Anand and Fabiano Caruana. Simon Williams is one of the leading practitioners of the classical Dutch and wrote more than one book on the opening.Theory
White most often fianchettoes the king's bishop with g3 and Bg2. Black also sometimes fianchettoes the king's bishop with ...g6 and ...Bg7 (the Leningrad Dutch), but may instead the bishop to e7, d6 (after ...d5), or b4 (the latter is most often seen if White plays c4 before castling). Play often runs 2.g3 Nf6 3.Bg2 e6 4.Nf3 (4.Nh3 is also possible, intending Nf4–d3 to control the e5-square) 4...Be7 5.0-0 0-0 6.c4 and now Black chooses between 6...d5 (the characteristic move of the Stonewall), 6...d6, the Ilyin–Zhenevsky Variation (less popular today), or Alekhine's move 6...Ne4!? retaining the option of moving the d-pawn either one or two squares. The opening's attacking potential is shown in the Polish Immortal, in which Miguel Najdorf, using the Stonewall Variation, sacrificed all of his to win by checkmate.Main variations
There are many variations and lines, but the following three are considered part of the main theory of the Dutch Defence.Leningrad Variation
In the Leningrad Variation of the Dutch Defence, Black fianchettos the dark-squared bishop. From g7, this bishop will not only be a good defender of the king, but also an active piece on the . The game may proceed 1.d4 f5 2.c4 Nf6 3.g3 g6 4.Bg2 Bg7 5.Nc3 0-0 6.Nf3 d6 7.0-0 Qe8. The g2-bishop helps protect White's king against Black's possible kingside aggression, and this bishop would possibly be blunted by the f5-pawn if it were instead to develop to d3. The opening code for the Leningrad Variation in the Dutch Defence is A87 to A89 in the ''Stonewall Variation
In the Stonewall Dutch, Black plays ...d5 in the opening and secures a tight grip of the e4-square. A possible example is 1.d4 f5 2.g3 Nf6 3.Bg2 e6 4.Nf3 d5 5.c4 c6. The ''ECO'' codes for the Stonewall Variation of the Dutch Defence are A90 to A92: * A90: Stonewall Variation * A91: Stonewall Variation with Nc3 * A92: Stonewall Variation with c4 and Nc3Staunton Gambit
An aggressive attempt by White to sacrifice a pawn with 2.e4 in exchange for rapid development and attacking chances against Black's Dutch setup. Named after Howard Staunton, who introduced it in his match against Bernhard Horwitz. The Staunton Gambit was once a feared attacking line, but it has been out of favour for over 80 years. GM Larry Christiansen and International Master Jeremy Silman have opined that it "offers White equality at best". The ''ECO'' code for the Staunton Gambit in the Dutch Defence is A83.White continuations
The traditional involves White playing 2.c4. More commonly, White will start with 2.g3. Some common variations are: c4 is played after g3 and Bg2; c4 is played after Nf3; and c4 is played after 0-0. Examples: * traditional: 2.c4 Nf6 3.g3 g6 4.Bg2 Bg7 5.Nf3 0-0 6.0-0 d6 * common: 2.g3 Nf6 3.Bg2 g6 4.Nf3 Bg7 5.0-0 0-0 6.c4 d6 ()Other second moves
White has various more aggressive alternatives to the standard moves, including: * 2.Nc3 Nf6 (or 2...d5) 3.Bg5, the Raphael Variation * 2.Bg5, the Hopton Attack; e.g. 2...Nf6 (2...g6 is the most popular move) 3.Bxf6 exf6 4.e3 or e4 * 2.Bf4 or 2.Nf3 and 3.Bf4, the London System * 2.g4, the Krejcik Gambit * 2.e4!?, the Staunton Gambit * 2.h3 followed by 3.g4, Carl Mayet introduced this completely different gambit approach to the Dutch in 1839 against von der Lasa. Von der Lasa later published analysis of this line in the first edition of the '' Handbuch des Schachspiels''. Viktor Korchnoi, one of the world's leading players, reintroduced the line into tournament practice in Korchnoi– Känel, Biel 1979. GM Christiansen later concluded, as von der Lasa and Staunton had done over 140 years earlier, that Black could get a good game by declining the gambit with 2...Nf6 3.g4 d5! * 2.Qd3, the Alapin Variation Black sometimes starts with the move order 1...e6 to avoid these lines, although Black must then be ready to play the''ECO''
