Parent Queen's Pawn Game

The London System is an opening system in chess where White opens with 1.d4 and develops the dark-squared bishop to f4, then supports the d4-pawn with pawns on e3 and c3. The other bishop is developed to d3 (or occasionally e2) and the knights typically to f3 and d2. This set-up often results in a closed game . The London System can be used against virtually any Black defence and thus comprises a smaller body of opening theory than many other openings. Although it has a reputation as a solid opening, the London System has faced criticism for its tedious nature and lack of dynamic play . [1] [2] [3] [4] [5] [6]

The rapid development of the dark-squared bishop in the London System can be contrasted with the Colle System, in which the queen's bishop typically remains on c1 during the opening phase of the game. [7]

History

The British-American James Mason was the first master-level player to regularly employ the London System, including at the strong 1882 Vienna Tournament (in which he finished third) and later at tournaments at London (1883) and New York (1889). The opening did not catch on, and received limited outings in master play in subsequent decades. It did, however, appear with some regularity in the games of certain masters, including F.J. Lee, Joseph Henry Blackburne and Akiba Rubinstein.

The name London System derives from the reappearance of the opening on seven occasions in the very strong London tournament of 1922, including in games by José Raúl Capablanca, Alexander Alekhine and Akiba Rubinstein. After this tournament the opening remained rare in master practice, but the London set-up soon became the standard response for Black against the Réti Opening (this line being named the New York Variation, after its use in Réti–Capablanca during the New York 1924 tournament).

Although the London System remains rare in grandmaster tournaments, it has been played occasionally by players including Bent Larsen, Tony Miles, Teimour Radjabov, Vladimir Kramnik and Fabiano Caruana, and more frequently by players such as Gata Kamsky, Levon Aronian and Magnus Carlsen. During the 21st century the London System has become popular amongst club-level players due to its solid nature, clear plans and lack of aggressive responses by Black. One of the most famous games of the 21st century utilizing the London System was round 6 of the 2023 World Chess Championship between Ding Liren and Ian Nepomniachtchi, in which Ding used it to win with the white pieces.

White set-up

The London System consists of a set-up for White employing the following moves (which can be played in a variety of move orders ): d4, Nf3, Bf4, e3, Bd3, Nbd2, c3. The move h3 is often also played, enabling the bishop on f4 to drop back to h2 if attacked, thus remaining on the same diagonal and continuing to influence e5.

Following the publication of the influential 2005 work Win with the London System by Sverre Johnsen and Vlatko Kovačević, it has become common for White to prefer to develop the queen's bishop to f4 on move 2 (rather than opting for 2.Nf3 and then 3.Bf4, as had previously been common). Johnsen and Kovačević note that, in the case of 2.Nf3, if play proceeds 2...c5 3.Bf4?!, then 3...cxd4 4.Nxd4 Nd7 "may already be better for Black". [8] Meanwhile, Kiril Georgiev notes in Fighting the London System that "The idea of delaying the [Nf3] development is to avoid the famous line [1.d4 d5] 2.Nf3 Nf6 3.Bf4 c5 4.e3 Nc6 5.c3 Qb6 6.Qb3 c4 7.Qc2 Bf5, when White should retreat [the queen] ingloriously to c1." [9]

Black responses

White's future plans will depend upon Black's choice of set-up. Black has a particularly wide range of possibilities in the early stages as White's London structure exerts little influence on Black's side of the board. Black may therefore develop freely. Common options include:

A popular response to the London System at higher levels of play is an early ...c5, allowing ...Qb6 (aiming at White's weak b2-pawn, which is no longer defended by a bishop on c1). This seeks to disrupt White's comfortable development system. The line 1.d4 Nf6 2.Bf4 c5 3.e3 Qb6 was considered by Johnsen and Kovačević to be the most critical line. [10]

A sample line in the Rapport–Jobava London: 1.d4 Nf6 2.Bf4 d5 3.e3 c5 4.Nc3 cxd4 5.exd4 Nc6 6.Qd2 Bf5 7.0-0-0

A modern development named after grandmasters Richárd Rapport and Baadur Jobava, this system still has considerable surprise value. It combines Bf4 with Nc3 (this knight would usually be developed to d2 in the standard London System) creating potential threats against Black's c7.

The Pirc Defence is a chess opening characterised by the response of Black to 1.e4 with 1...d6 and 2...Nf6, followed by ...g6 and ...Bg7, while allowing White to establish a centre with pawns on d4 and e4. It is named after the Slovenian grandmaster Vasja Pirc.

The Nimzowitsch-Larsen Attack is a chess opening typically starting with the move: 1.b3 but sometimes introduced by the move order 1.Nf3 and then 2.b3. The flank opening move 1.b3 prepares to fianchetto the queen's bishop where it will help control the central squares in hypermodern fashion and put pressure on Black's kingside.

The King's Indian Attack is a chess opening system where White adopts the setup more commonly seen being played by Black in the King's Indian Defence. The King's Indian Attack is characterised by the following moves: the central pawns are developed to e4 and d3, the knights are developed to d2 and f3, the king's bishop is fianchettoed at g2 following the g-pawn's move to g3, and White castles kingside.

The Stonewall Attack is a chess opening characterized by White playing pawns to d4 and e3, bishop to d3, knight to d2, and then completing the Stonewall structure by playing pawns to c3 and f4. This set-up is usually achieved by a 1.d4 move order but transposition is also possible via Bird's Opening, 1.f4. The Stonewall Attack is a system; White heads for a very specific pawn formation, rather than trying to memorize long lines of different variations. Black can set up in various ways in response, but MCO-15 gives the following as a main line: 1.d4 d5 2.e3 Nf6 3.Bd3 c5 4.c3 Nc6 5.f4.
